Assisted Braking Devices

Assisted Braking Devices have been a part of American climbing for a long time. By 1992, American climbers and belayers were alternately condemning and commending the new tools, and most of those perceptions persist today.  In many cases, the GriGri is unfairly given credit for securing belays in an unprecedented way.  In other cases, the GriGri is maligned as symbolic of complacency, poor belaying, and laziness.  Over the years, American belayers have over-heard epithets like:

“The GriGri promotes lazy belaying.”

“The GriGri has an automatic brake.  You can’t mess it up.”

“GriGris might be great for toproping or sport climbing, but it’s unsafe to use them for trad.”

“GriGris are the industry standard for belaying a toprope.”

These statements and the reductive thinking behind them have inhibited Assisted Braking Devices from taking their logical place in American climbing. This article will seek to unpack and explain some of the historical and cultural underpinnings of assisted braking devices like the GriGri in order to explore how these devices have gotten to the point that they are neither appreciated for their contributions to climbing nor adequately respected for their complexity and intricacy.  

To get there, we will need to clarify the current and historic role of backups in any technical system related to climbing. We will need to explain how these tactics long preceded the invention of the GriGri, because they are still just as important in the era of assisted braking devices as they were before GriGris hit the scene in the early ’90s.  Then, every climber will be better equipped to discover what Assisted Braking Devices offer to the overall security of a belay or rappelling system.

This article will qualify the use of Assistant Braking Devices according to the following principles:

• Assisted Braking Devices, when used correctly, provide a reliable backup to any belayer.  

• Assisted Braking Devices, when used correctly, offer the greatest movement economy when delivering slack to a lead climber.

• Unlike Manual Braking Devices (like any tube style device), ABDs have widely variable performance characteristics from one model to the next.

Backups

In climbing, we use backups all the time.  We use them as an integral part of our systems and we often use words like redundancy and security when we’re talking about backups.  In every case, the basic concept is the same: a climber relies on one system to stay safe, and there is another system that acts as a back-up in case the primary system fails or malfunctions.  

Let’s look at some of the most common examples:

Climbing

Rappelling

Anchoring

Backups are a great idea, and they help us have a lot more confidence that we’re going to survive an error, a slip, an oversight, or a freak occurrence.  When we choose not to use a backup, we’re often flirting with unnecessary risks.

Let’s look at some examples:

Free Soloing

Lowering with an MBD without a backup

It is not common to think of backups in this way. However, when a climber analyzes the role of backups and looks at all climbing practices through that lens, it is difficult to escape the conclusion that holding a climber’s weight with a manual braking device and lowering a climber with that same device is tantamount to free-soloing. Unlike free-soloing, though, belaying usually involves two people; they are both complicit in this arrangement.

Before Assisted Braking Devices were an option, conservative belay teams relied on backups that are still options today. 

Since climbers are often standing around in groups of three or four, it's easy to offer a backup belay.

If a backup belayer is not standing behind the belay device, in the braking plane of the device, the value of the backup might be nominal.

These backup knots, tied every 10 to 15 feet, provide a backup to the belayer when she does not have someone available to provide a backup belay.

While a friction hitch can provide an adequate backup for lowering, it takes practice to tie this hitch while holding a climber,  and it won't work on every harness' leg loop design.

A careful observer of these traditional forms of backup will notice that an incompetent belayer (or pair of belayers) still has the capacity to injure a climber. So, an unstated but obvious addendum to the application of any backup to any system is that incompetence is presumed to be negated. It’s an important distinction to make. Gross incompetence can override all reasonable backup systems, and safeguarding against incompetence quickly becomes impracticable.  

Belaying systems presume functional cooperative competence as a starting point, and backups safeguard unforeseen forces and circumstances that can unexpectedly incapacitate a belayer. So, it’s important to combine fundamental belay principles to any belay device, regardless of the braking apparatus. All devices require a belayer to keep a brake hand on at all times, slide or alternate the brake hand only when the rope is in the braking plane of the device, and use the hand wrist and arms according to their natural strength.

Assisted Braking Device = Backups

An assisted braking device, operated within the fundamental principles of belaying, is an especially valuable tool if climbing teams prioritize backups. If a belayer takes an honest self-assessment of all the things that might thwart the best intentions of a diligent and competent belay, then it is difficult to justify not prioritizing backups. It is perfectly reasonable, and perfectly human, to accept that any number of sights, sounds, and distractions compete for a belayer’s attention. Other climbers, friends and acquaintances, passersby, flora and fauna, changes in weather, they all distract even the most committed belayers. In these perfectly predictable and likely circumstances, the assisted braking mechanism of an ABD can provide the ready-to-go attentiveness that the belayer momentarily lacks.

More persuasively, there are occurrences in the climbing environment that can easily incapacitate a belayer, regardless of their position relative to the climber (above or below). If a belayer is willing to indulge the imagination, these hazards quickly accumulate:

• Rockfall generated by climbers above in a separate party

• Rockfall generated by a climber in one’s own party

• Natural rockfall

• Icefall (for all the same reasons)

• Avalanche (for all the same reasons)

• Electricity of all kinds

• Aggressive Fauna (stinging insects and arachnids, snakes, large predators)

• Aggressive Flora (treefall, deadfall, prickling plants, poisonous plants)

• A leader climber falling and impacting the belayer

• Medical problems (allergies, asthma, diabetes, seizures, other chronic conditions)

Accident archives and anecdotal evidence demonstrate, again and again, that the selection of an ABD provides belayers and climbers with a backup should any of the aforementioned hazards incapacitate the belayer.

On one notable example, a pair of proficient climbers had a spectacularly close call in Eldorado Canyon in 2008. In much the same manner catalogued above, the leader climber dislodged a large rock during a lead fall.  That rock fell and hit the belayer.  The belayer, having selected an ABD, managed to arrest the leader’s fall despite the severe injuries he sustained.  Had the belayer selected a manual breaking device instead, like an ATC, without any sort of backup, the leader would have likely been severely injured as well. As it turned out, the leader was able to run for help and assist rescuers to evacuate his partner.

An ABD is not a panacea for mishap or incident, but it does provide all belay teams, like this team from Eldorado Canyon, with a margin of error. Surely, that’s an adequate incentive for any climbing team to learn more about ABDs, and it’s a sound reason to learn to use them correctly. 

Movement Economy while Lead Belaying

Many assisted braking devices offer the greatest economy of movement when delivering slack to the lead climber. Even though many belayers assert that ABDs have cumbersome mechanics resulting in a jammed rope and an inability to provide adequate slack, most of these assertions are based on a lack familiarity with the techniques needed to use an ABD to belay a lead climber.

The key to this movement economy involves a stationary brake hand. It might be helpful to see fundamental belaying with an MBD contrasted with an ABD to demonstrate this concept explicitly.

Many ABDs, by contrast, keep the brake hand stationary, eliminating an entire step in the belay cycle. As result, there can be a 50% increase in overall efficiency when the belayer delivers slack to the leader.

This movement economy is especially useful on easy or moderate terrain, when the leader is unlikely to fall. One of the greatest hazards to the leader in that terrain might be getting tripped or snagged by an inadequate supply of slack from the belayer.  An imperative to provide adequate slack is also common on low-angled terrain when the leader tends to move in long strides. That kind of movement necessitates adequate slack because the leader’s balance is often precarious and unstable. In any case, it may be valuable for a belayer to opt for a belay tool and technique that provides slack to the leader as efficiently as possible while also adhering to the fundamental principles of belaying.

Variations among ABDs

While the Petzl GriGri tends to represent the entire genre of ABDs due to its popularity and history, it is not the only ABD available. A careful analysis of the various functions, applications, and performance characteristics of each ABD should help belayers make an informed choice when they select a device. 

Applications

ABDs are typically deployed in the following contexts, although many of these applications are not necessarily recommended by the manufacturer. Manufacturers tend to create recommended use guidelines that pertain to the most common usage, and any application outside of that usage is implicitly discouraged. Nevertheless, many climbers rely on these kinds of applications, so it will be important to disclose the nature of each application, even though the manufacturers may not. These applications will be listed from most to least common. An ABD’s ability to perform these applications and functions help climbers decide when and how to use one tool or another.

1.     Belaying a counterweighted toprope. In a toproping scenario, ABDs are commonly deployed by institutional programs, climbing gyms, and professional climbing instructors. The values of an ABD as a backup are especially conspicuous to these users.

2.     Belaying a leader in a counterweight arrangement. The belayer’s body weight anchors a leader’s ascent in protection increments. Sometimes this arrangement is distorted by the use of a ground anchor or a connection that protects the belayer from an upward pull. An ABD can predictably increase the impact forces generated by lead falls. Impact forces are measurably increased on the belayer’s body, the climber’s body, and the protection/anchor. In most scenarios lead climbing scenarios, however, the differences in impact force would not have catastrophic consequences.  

3.     Rappelling. If a rope is somehow fixed or counterweighted, an ABD can be used as rappel tool on a single strand of rope.

When a single strand of rope is fixed, blocked, or counterweighted, an ABD can be used for rappelling.

"Rappelling with GRIGRI takes training, and it is important to system check ensuring proper rigging and connection."-Petzl

4.     Rope Ascension. If a rope is somehow fixed or counterweighted, an ABD can be used as a progress capture in an ascension system.

Many climbing instructors, like this one, learn to use an ABD for rope ascension.  As an improvised progress capture, these tools can be effective.

5.     Direct Belay. ABDs are often used by belayers to top-belay a second climber directly off the anchor. When top-belaying, direct belays are particularly advantageous. ABDs create unique challenges when belaying a leader in direct belay configurations.

Direct belay applications must allow an ABD a full and uninterrupted range of motion.  If the device is laying on a slab or crammed against a protruding feature, the assisted braking function can be compromised.

Performance Characteristics.  

ABD manufacturers will each try to convince consumers that their products represent the most secure, reliable, easy-to-use device on the market. The truth is that climbing has diverse contexts with diverse environments, climates, and risks. That diversity is further compounded by the number people who climb: big people, small people, big hands, small hands, right-handed people, and left-handed. Some people are missing digits or limbs, and that might make one product more advantageous than the next.

When combined with function and the need for multi-functionality, each device will also have an array of performance characteristics that depend on each individual user’s style, body type, and unique challenges. Asking the following questions of every ABD will guide a user to the right model.  

Stationary Brake Hand: Does the manufacturer recommend a belay technique that allows the brake hand to remain stationary? Many devices do allow for this movement economy, and it is one of the most persuasive reasons to select an ABD in the first place.

Mechanical Braking or Passive Braking:  Is the assisted braking function mechanical or passive?  Mechanical Assisted Braking Devices, like the GriGri 2 or Vergo, have moving cams, clamps or swivels that pin the brake strand of the rope.  They are typically bigger and heavier than their passive counterparts. Their performance can be challenged in wet, snowy, or icy conditions. They can provide smooth lowers, multi-functionality, and reliable braking, though.

Passive Assisted Braking Devices exaggerate the “grabbing” quality of any aperture or tube style belay device. The “grabbing” effect is so severe, it effectively brakes the rope, providing the belayer with a backup.

Ergonomics:  Does the recommended use of the tool force the belayer to sustain unnatural, painful, or uncomfortable body positions?  Test the ergonomics of a device in all the application contexts. For example, the body mechanics involved in using a GriGri 2 are quite natural and comfortable for rappelling and counterweight belaying. But, lowering with a GriGri in a direct belay configuration requires an awkward manipulation of the GriGri 2 handle.  

Reliability of Assisted Braking Function:  Does the Assisted Braking Function perform reliably in the widest range of conditions and circumstances?  What are the known malfunction conditions? No ABD is automatic and 100% reliable.  They all have quirky and unique failure mechanisms that range from interference in the braking function’s range of motion, interference caused by precipitation (frozen or otherwise), inappropriate carabiner selection, or rope entrapment. Manufacturers don’t always advertise these failure mechanisms. 

Multi-functionality:  Does the device perform more than one function in climbing?  Do all the functions of the tool fall under the device's recommended use?  Are some functions discouraged, or are they simple NOT encouraged?

Smooth lowering and rappelling:  When lowering and rappelling, is the belayer able to control the rate of descent and keep that rate constant, without sudden halts or acceleration?  The ability to adjust the rate and the consistency of the rate varies from one tool to the next, and it can be especially inconsistent when using ropes at the extreme ends of the recommended range, ropes that are wet, or with smaller statured people.

Ambidextrous Usage:  Is the device effectively unusable by a right or left-handed belayer?  Does it function equally well with either handedness?  Many devices do not offer a compelling left-handed technique. Left-handed belayers often learn to use their right hands to belay because there is not a recommended technique, or the recommended technique is not as effective as simply learning the right-handed technique.

Size and Weight:  How big and how heavy is the tool?  Are there lighter options that accomplish the same functions and have the same performance characteristics otherwise?  In climbing, the size and weight of equipment can often make a big difference to the overall enjoyment and success of the team. All other things being equal, why not have a lighter, more compact tool?

Rope twisting: Does the device alter the plane of the rope’s travel?  When ropes move continuously in the same plane of travel, the rope is less likely to twist.  When that plane alters, say from a horizontal to vertical plane, twisting the rope is the unavoidable consequence.

Easy to learn, easy to teach:  How long will it take me to learn to use the tool?  Devices that are not ergonomic, have intricate parts and setups, and operate differently than other tools can often be more difficult for a belayer to learn to use correctly.  It shouldn’t take months and months of practice to learn to use a piece of belay hardware.

Rappelling

Rappelling was once considered a prerequisite skill for any climber navigating 5th class terrain. It was a mainstay of introductory texts, climbing classes, and novice climbers were often taught to rappel before they ever climbed their first pitch. 

Much of that has changed, and large numbers of climbers enjoy all kinds of outings where rappelling is both unnecessary and perhaps unwise. Many toprope venues do not require rappelling during setup, many sport climbing venues are equipped to quickly clean anchors by lowering, bouldering usually does not require any form of technical ropework (much less rappelling), and most modern climbing gyms flatly disallow rappelling. As a result, rappelling is something that many climbers understand conceptually (having lowered each other) but fewer have actually experienced. As a result, when rappelling accidents happen to beginners we often discover that the contexts of rappelling were not perfectly understood, the fundamental physics of rappelling were confused, and the variability of the rigging was understated or oversimplified by mentors and instructional materials. 

A generation ago, every climber learned to rappel. Early rappel techniques, like the Dulfersitz, helped climbers learn the relationship between the body and rope friction. These techniques still work, but they don't provide many options for backups or added security.

By comparison, experienced climbers have often rappelled hundreds or thousands of times, but an unfortunate number of us also seem to be randomly involved in rappelling accidents. In these cases, preventative practices like knotted rope ends, using backups, and a system of careful double-checks were often overlooked or ignored, even though the value of these techniques is undisputed. 

In this article, we hope to create a resource for novice climbers to understand what rappelling is, the contexts in which it happens most commonly, and a set of principles that should govern the rigging. We also hope to address any reader that may be well into their rappelling career. Perhaps some will find reasons to adopt practices that they have historically ignored, or revise the practices they are currently committed to using regularly. In some cases, this article may simply validate what a reader is already doing, but in that case we hope it might also give them a vernacular for communicating with their friends, students, and mentees. 

What is rappelling?

To put it most simply, rappelling is just lowering your own mass down a climbing rope. In belaying, the belayer remains stationary and the rope moves. In rappelling, the rope remains stationary, there is no belayer, and the rappeller is the thing that is moving.

Once a climber has rappelled a few times, these distinctions seem painfully obvious. But, as thousands of climbing instructors will attest, until a person has experienced the fundamental difference between being lowered and rappelling, it’s not obvious at all. A rappeller has independence, agency, and control in a way that a person being lowered does not. That can be advantageous, but it also means that rappellers sometimes lose the advantages and redundancy of team work.

There are two main variations to rappelling mechanics: fixed-line rappelling and counterweight  rappelling. In fixed line rappelling, a climbing rope is connected to an anchor, the rope remains stationary, and the rappeller can rappel all the way down to the other end of the rope. In counterweight rappelling, a climbing rope is not fixed.  Instead the rope runs freely through a rappel station, set of carabiners, or around an object. In this arrangement, a rappeller must capture both strands of rope within the rappel in order to counterweight around the rappel anchor point, and the rope can be retrieved from below.

In counterweight rappelling, a rope runs freely through a rappel fixture.  As a result, a rappel device must capture both strands of the rappel rope. The rappeller effectively counterweights themselves. 

In fixed line rappelling, the rappel rope is affixed to an anchor, so the rappeller does not need to effect a counterweight. The rappeller can rappel a single strand of rope.

When do climbers rappel?

Climbers rappel for two main reasons, in two primary contexts: single pitch rappelling and multistage rappelling. Both options are slightly different, and a climber learns to adapt the rigging, the device selection, and the anchoring accordingly.

Multistage rappelling happens when climbers ascend a multipitch climb and descend the feature through a sequence of rappels. They climb a big wall, up up up, in sections, and then they rappel, down down down, in sections. 

Single pitch rappelling. Climbers also occasionally rappel when they clean anchors in a single pitch setting. Sometimes, local custom or policy require climbers to rappel when they clean. Sometimes, lowering is not an option. Sometimes, rappelling is needed in emergencies.

“The first step in avoiding any climbing incidents is good prior planning.  Get all the information you can from the guidebooks.  It is also a good idea to take a copy of a route topo—even if you have done the route before.  And consider looking at blogs and talking with friends or acquaintances for information.

Equipment inspection before each season—and before each climb—is always important. Is it time to retire your ropes, slings, or harness? Look closely at all the gear to see if there are any obvious wear and tear issues and consult the manufacturers for recommendations.

Double-check any critical system carefully before committing to it.  Look through and inspect all critical links, carabiners, the rope’s integrity, the harness’ key points (buckles, belay loops, and connection points).  It’s always helpful to have a partner nearby so that climbers can double check each other.

Decide how the climbing team will communicate before the need for communication arises, minimize the amount of words needed to relay information unambiguously, and focus on communications that initiate action.”

Fundamental Principles of Rappelling

1. You should be secure during the setup because rappels are often rigged in proximity to cliff’s edges and precipices, and even careful and experienced climbers are endangered by that kind of exposure. 

2. You should use appropriate backups because a variety of factors make it likely that a rappeller will lose control of the rappel.  

3. You should manage the ends of the rope because we often rappel in the dark, when tired, with unfamiliar ropes and in unfamiliar terrain, and since we often rappel rapidly, the ends of the rope can present a unique hazard. 

4. Avoid Entanglements. Rappelling involves a lot of rope that must be carefully managed and rappel devices that notoriously entrap hair, hoody-strings, straps, and clothing, the last principle asks us to manage the rope and manage ourselves to avoid entanglements.

Security During Setups

There are lots of ways to be secure during setup. Generally, the options fork into two initial categories: technical and non-technical. Non-technical security does not involve anchors or tethers or carabiners. It’s simply staying away from a cliff’s edge or staying seated when setups are awkwardly close to a cliff’s edge.

Technical security uses some sort of tether, sling, PAS, or the climbing rope to connect the climber to an anchor during setup. The context of the rappelling usually inspires a wide range of variations among the tethering methods. 

With their back turned towards a precipitous cliff's edge and their attention focused on setup tasks, these climbers are using technical security (a tether and locking carabiner) to stay secured during setup. 

“Notes on appropriate set up:
Be sure that the rope actually passes through the rappel device properly, that a bight includes the carabiner and that the carabiner / extension is properly attached to harness. If pre-rigging – all partners get eyes on each other’s systems.”

— Rob Hess, UIAGM/IFMGA. Accidents in North American Mountaineering 2012.

Appropriate Backups

A rappel backup effectively provides a backup for the rappeller’s brake hand. If the rappeller were to release their grip of the brake strand for any reason (losing control, rockfall, medical emergency) the backup would effectively hold the rope instead of the rappeller’s brake hand. There are three common variations: a friction hitch backup, a firefighter’s belay, or the use of an Assisted Braking Device.

Friction Hitch Backup

A Friction Hitch Backup can be quickly paired with any tube style rappel device, but the setup has to be precisely configured. If a backup doesn't work when you need it to, it constitutes little more than wasted time, material, and effort. Common examples include friction hitch backups that are poorly dressed, iced or frozen, or they don’t assert enough friction to grip the brake strands with adequate braking power. Also, if a friction hitch backup is too long, it will push up against a rappel device, pushing the hitch along instead of allowing it to grip the brake strands.  It’s important to get the lengths just right so that the backup engages. On steeper rappels, an inverted rappeller can easily bring the friction hitch into dangerous proximity to the rappel device. 

Precise rigging is vital to an effective rappel backup. It's not enough to apply a friction hitch; the distances and positions of all the pieces have to be just right.

When we don't pay attention to the details, when the rigging is imprecise, our backups are ineffective. This climber has wasted a lot of time and energy rigging a backup that won't work.

Since the rigging of friction hitch backups has to be so precise, many rappellers prefer to extend their rappel devices away from their harnesses. In this configuration, the friction hitch backup can be connected directly to the belay loop. In general, extensions allow for a greater margin of error in the rigging of rappels and their backups, which is advantageous.

An extension built with a double length nylon sling positions a rappel device far enough from a belay loop that almost any friction hitch backup will be effective.

An autoblock friction hitch is a great option when tying a rappel backup.  A small loop of 5mm nylon can be quickly deployed for the task.

The auto block is tied by enwrapping the brake strand(s) of the rappel, as many times as the material length allows...

...and the autoblock is completed by rejoining the nylon loop with the locking carabiner.

There are eternal debates about the type and style of extension used to separate a rappel device from the harness. Suffice it to say, there are many adequate options. As long as the option is adequately strong and secure, without compromising overall efficiency, it's probably a good one. Some of the most common alternatives include a Personal Anchoring System (PAS) or quickdraw with locking carabiners. For multipitch rappelling, an extension that has a modular leg can be used to both extend the rappel and clip into anchors during rappel transitions.

A locker draw extension.

A PAS extension.

An offset extension is great for multistage descents.

Firefighter’s Belay

Firefighter’s Belays are effective backups too, but they have to be executed correctly.  To provide a firefighter’s belay, the belayer should be attentive, with eyes on the rappeller and hands on the brake strand(s) of the rope. If the rappeller were to lose control of the rappel, the attentive belayer would pull down assertively on the brake strand(s) in order to effect enough braking force to halt the rappeller’s descent. Much like a poorly rigged friction hitch backup, a firefighter’s belay that is inattentive, loose, or off the fall line will likely be ineffective.

When this climber offers a firefighter's belay, she means it.  She's attentive and ready to halt the rappeller at any moment.

When rappellers lose control it happens quickly and unexpectedly, but a quick and firm tug on the brake strands will bring the rappeller to a halt.

Managing The Ends of the Rope

Managing the ends of the climbing rope is often a vital technique to keep rappellers from rapping off the end of the rope. Commonly, the ends of the rope are either conjoined or bulky stopper knots are tied, such that the knot that would ram into a friction hitch or rappel device, reliably arresting the rappel.

A pair of bulky stopper knots are among the easiest ways to manage the ends of the rope.

Conjoining the rope ends and carrying them to the ground has the added advantage of managing the ends of the rope while also avoiding tossing ropes down the cliff.

Avoid Entanglements

It’s important to keep anything from getting snagged in a rappel tool, and it’s also important to keep one’s ropes organized and moving fluidly. Entanglements of hair, clothing, or the rope can create serious problems while rappelling, especially in adverse conditions.

Tossing Ropes

It is rarely necessary or expedient to throw ropes down a cliff. Often, the tails of rope can be gently lowered to the ground, or a bight of rope can be lowered and the tails carried to the ground by the rappeller. It’s also likely that tossed ropes will land on other climbers, in places that are difficult to retrieve (trees or cracks), or places that are awkwardly gross (mud, poop, carrion, etc). A rappeller can avoid entanglements by avoiding tossing ropes.

Conclusion

It is a worthwhile thought experiment to imagine how climbers create margins of error, how we use backups, and how/when we selectively (and hopefully carefully) disregard those techniques. Typically, a climber navigating 5th class terrain uses a rope system to mitigate the risk of ground or ledge impact, but sometimes we intentionally neglect to place enough protection to effectuate the rope system we’re tied to. Those are enormously risky behaviors, but we tend to engage in them quite readily when we perceive there to be a low probability of incident, like when the climbing is easy or unremarkable. Similarly, a small portion of climbers free-solo in 5th class terrain, and their calculation is identical: they perceive there to be a low probability of incident, and they therefore eschew a rope system altogether.

The indisputable reality is that good climbers fall off of easy terrain every year.  Experienced rappellers lose control, rap off the ends of rope, or incorrectly rig their rappels. As a species, humans don’t always reconcile their rational/analytical response to risk with their intuitive/emotional response. As a result, best practices like using backups, managing the ropes ends, staying secure during setups, and careful double checks are often characterized as overly conservative, burdensome, and slow. Similarly, eschewing these practices altogether, which is actually tantamount to free-soloing in a demonstrable ways, can be characterized as a matter of preference, style, or status.

Instead, take the time to appreciate that each rappel is merely similar to all previous rappels. In quantifiable ways, every rappel is also dissimilar to all previous rappels.  If that is true, the way we rappel is also merely similar to the way we rappelled on every previous occasion. The solutions we use to descend our next rappel will be unique in appreciable ways. So, the fundamental principles of rappelling can be used as a unique questionnaire for every rappel.  A rappeller should have compelling and accurate responses to each of these questions before rappelling:

Am I secure while I setup the rappel?

Am I using appropriate backups?

Am I managing the ends of the rope?

Am I avoiding entanglements?

Climber Communication

 

In the United States, many incidents and inefficiencies are caused by miscommunication within a climbing team. Often, highly consequential information needs to be relayed between climbers and belayers, and miscommunicating that information has unfortunately resulted in grave consequences. At the American Alpine Club, we have been gathering these unfortunate stories for over a century, and many incidents could have been entirely avoided had the team communicated more clearly. However, any skill that involves the use of language tends to resist standardization; it’s a challenge that has frustrated American climbers in all disciplines.

One of the first climbers to try to address these challenges was Paul Petzoldt. In The Wilderness Handbook he writes, “Unindoctrinated by the standard European techniques and philosophies of [the world war-era], I developed some new skills and ideas. I invented the first voice-signal system (now universally used in America).” American climbers have largely adopted and gravitated to some version of Petzoldt’s verbal commands for the last 100 years, because his assertions are as true today as they ever have been. Petzoldt wrote:

The human voice is difficult to hear and understand on a mountain. The belayer might be out of his companion’s sight, words do not carry well around rock projections, wind and rain sometimes make conversations impossible, even at short distances. Because of such interferences, I have developed voice signals that are brief and intelligible even when faintly heard.

Petzoldt’s innovation was insightful, and it informs the concepts espoused in this article. But, the Petzoldt voice signals that sound so familiar to so many climbers, can easily be obfuscated by a busy crag, dialect or nuances in pronunciation, and by the use of names within the voice signals—names distort the syllabic distinction that Petzoldt originally devised.

Communication, as a concept, has to be grounded in something less complex than language or speech or any group of practices that is so easily undermined by the nuances of dozens of individual cultures. It’s important to remember that communication is not always about language. Climbers who do not have the ability to hear, to speak, or to see have always managed to communicate with others, and those individuals climb in the United States as well. There is a need to address climber communication in a way to focuses on the essential goal climbers are trying to achieve, and language is only one of many ways climbers communicate.

In this article, we will explore why communication is so vital to climbers. We will explore the principles that should govern communication in all contexts, and from those principles we will make recommendations that are mostly likely to work in most contexts.

Why is Communication so vital to climbers?

Communication often results in establishing or relinquishing safety systems, like a belay, and establishing or relinquishing a safety system inappropriately can be dangerous.

AND

Climbing environments make communication difficult. Climbers find themselves in cacophonous surroundings (windy and rainy conditions, busy crags and climbing gyms with lots of competing voices, loud environments like roadsides, roaring rivers and streams, chirping and singing wildlife). Climbers are often out of sight of one another, making traditional nonverbal communication difficult.

Climbing environments often make communication difficult.  The sound of the ocean, in this case, makes it important address the fundamental principles of effective climber communication before the climbing starts.

Fundamental Communication Principles

Fundamentally, all formal climbing communication serves to mitigate the inherent hazards of climbing. Many of the climbing commands typically employed concern management of the rope system, which in turn affects the belay and the security of the person being belayed. The simple command “On belay” may be the best example of a rope system command. An additional set of commands exists to address the hazard of falling objects, “Rope!” and “Rock!” being the most prominent examples.

Effective formal communication in a climbing system relies on commands that follow three foundational principles:

Communication Agreement. Communication between climbers and belayers should be anchored to a script that is agreed upon prior to the need for the communication.

Communication Precision. Communication should strive to minimize the amount of oral traffic needed to relay information between parties.

Communication Action. Communication should imply an impending action, and therefore should unambiguously initiate that action. Communication also may be used to affirm the completion of an action.

Communication Agreement

Climbing commands are only effective if all members of the climbing party agree on what commands will be used and the explicit actions they imply. For example, there are a number of commands associated with eliminating slack from a belay system, including, “Take,” “Tension,” “Up rope,” and “That’s me.” Each of these commands carries a nuanced meaning that must be known by the belayer in advance in order for her to respond appropriately when her climber issues such a command.

Every climber can appreciate what it's like to call for tension in the rope system.  Paul Petzold originally specified "TENSION" as the preferred voice signal, because it has two syllables, just like all the other commands that involve tightening the belay.  Today, "TAKE" is a common command, but the single syllable can easily be confused with "SLACK," which is the opposite of what this climber wants right now.

Establishing different formal climbing commands prior to every climbing outing with a new partner can inconvenience the climbing experience in little ways, but it's almost always worth the a little inconvenience at the beginning of the day in order to avoid an accident. Once the communication agreement has been established, a climbing team can default to that agreement until the conditions or the context necessitates an adjustment.  

There are common tropes and patterns that speakers of American English will recognize, regardless of region or background. Still, slight variations persist from one group of climbers to the next, and climbers should engrain the ritual of affirming their communication strategy before the climbing outing begins. The most common theme in miscommunication-related incidents involve climbers who neglected to have a vital “agreement” conversation prior to their climb. A simple conversation would have alleviated the confusion.

Communication Precision

Another common theme in miscommunication is over-communication. The climbing team might attempt to rely on informal communication and conversation when precise and unambiguous commands are needed. The communication might be redundant and therefore unnecessary. In both cases, the climbing team fails to appreciate that precision (communicating a precise action, no more and no less) is a fundamental concept.

When conditions are challenging, informal communication should be entirely eliminated to prevent miscommunication of important formal commands. For example, if the leader has climbed around a corner and into the wind, she would be wise to only use formal climbing commands with her partner to prevent being taken off belay prematurely.

Similarly, redundant commands over-communicate and create ambiguity. Some novice lead climbers use the commands “Clipping” and “Clipped” to inform their belayer that they will be clipping the rope into a quickdraw. “Clipping” implies that the leader will need additional slack to clip the carabiner; the formal command “Slack” is already used to alert the belayer to introduce slack into the belay system. “Clipping” is therefore a redundant communication.

“Clipped” suffers from problems with both redundancy and ambiguity; two meanings may be implied. First, the leader may be asking the belayer to remove unnecessary slack from the belay system (in which case a number of commands may do the job). Second, the leader may also be asking the belayer to check the clip: is the leader back-clipped? Z- clipped? Often, this task is impractical or impossible for the belayer to accomplish. Finally, both, “Clipping,” and, “Clipped” are unnecessary assuming the belayer is attentive. No system of communication, even if it is fundamentally thoughtful, can compensate for inadequate belaying.

"CLIPPING" and "CLIPPED" are rarely vital communications if the belayer is attentive.  A climbing team that prioritizes precision will eliminate unnecessary communication in order to minimize ambiguity and miscommunication.

When communication become challenging, eliminating unnecessary command or conversation allows the climbing team to anticipate essential climbing commands based upon their previous communication agreement.

Communication Action

Communication should have a clear and unambiguous relationship with an impending action. For example, “Off belay,” is often used to initiate the deconstruction of a belay system. As any climber can appreciate, the action that corresponds to the communication is often highly consequential, and in many cases an affirmative response to the action helps signify the severity of the action that has occurred. Climbing teams will often use affirmative responses like “Belay off” to signify the completion of an important action. However, any command which does not include or affirm a call to action can easily be interpreted for something it is not intended to be, and such inactive communication should be avoided.

For example, some climbers use the command, “Safe,” or, “In direct,” to imply that they are secured to an anchor in some way. However, these commands are superfluous--there is no action for the partner to take in response to this command, nor is there a corresponding affirmation. Instead, the climber could simply say “Off belay” if intending to secure herself and belay from above as in a multipitch climb. Alternately, the climber could say nothing at all and simply request “Slack,” if cleaning an anchor on a single pitch climb, for example.

Fundamentals of Communication in Practice

The following examples explore the use of fundamental communication principles in real-world scenarios and demonstrate an application of those principles to scenarios that are familiar to many climbers.

Scenario 1: Casual cragging with lots of other parties.

Perhaps the most frequent scenario in modern climbing has the climber and belayer starting together at the base of a pitch. Whether leading or top roping, the commands used are the same. Drawing on the most common climbing commands in the United States, our climber, Maria, queries her belayer: “Jorge, are you on belay?”

As the formal climbing command is a call to action, Jorge physically checks the entire belay system, ensuring his belay device is loaded correctly, the carabiner is locked, his harness is fitted properly, the rope is running properly through an adequate anchor if appropriate, his climber’s harness is fitted properly, and his climber has tied into her harness correctly. When appropriate, Jorge also ensures both he and his climber are wearing helmets. Only after completing all of these checks and confirming them with his partner can Jorge say, “Maria, your belay is on.”

In their communication agreement, Jorge and Maria decided to use each other’s names in their verbal commands. This strategy is particularly important when communicating in a crowded location or noisy environment, such as a climbing gym or a busy sport climbing crag. In the multipitch setting, preceding the command with a name is equally important as it alerts the recipient that a command follows and ensures that adjacent parties do not misinterpret the other party’s communication for their own.

With climbing teams all climbing side by side, the use of names in voice signals is an advisable part of any communication agreement.

Jorge and Maria will use each other’s names to precede all of their verbal commands today, because that is part of their communication agreement, it is a precise way to specify which commands are directed to whom, and the teams needs a way to differentiate between vital commands that initiate action and the informal banter that will surely characterize their time at the crag.

Scenario 2: Multipitch Climbing

Jorge and Maria are now on a multipitch climb. They begin a pitch sharing a stance at an anchor together, so communication is straightforward prior to the lead. However, once Maria tops out the pitch, there’s a need for terse, precise, and unambiguous action-oriented communication. Belays will be deconstructed and the climbing team will be transitioning from one safety system to the next.

In their communication agreement, Jorge had two main concerns. Jorge wanted to know when exactly to start removing his belay device. He had an experience in the past when he thought the leader said “Off Belay.” On that day, the leader was actually shouting to a rappelling party, “I’m out of the way.” Jorge took the leader off belay prematurely that day, and he never wants to make that mistake again. On a completely separate outing, Jorge was taking his GriGri off the rope when the leader started pulling up the rope. The unexpected tug of the rope yanked Jorge’s GriGri out of his hands and it fell all the way down the cliff. Jorge doesn’t want to deal with either of these miscommunication problems again.

Maria and Jorge agreed that names will be less important today on this isolated climb; no other climbers are around. They’ve also agreed that when the leader shouts “Off Belay,” the belayer will immediately shout “Belay Off.” The leader will have one last chance to object, if Jorge has misheard the verbal command. Jorge agrees to wait a short second before deconstructing the belay.

Also, the leader agrees not to start pulling up rope until she hears the belayer shout “Maria, Up Rope.” It’s important for every climbing team to appreciate that Maria and Jorge could’ve agreed on a completely separate sequence here, and a completely separate set of commands to communicate that sequence. The vital point here is the relationship between prior agreement and precision; Maria and Jorge are being conscientious about both fundamental principles.

When the rope is tensioned against Jorge or his attachment to the anchor, he’ll inform his partner by saying, “That’s me.” This signals to Maria that the tension she feels in the rope is due to Jorge’s weight and not some other potential predicament, such as the rope being wedged in a crack or ensnared around a horn of rock. Maria’s call to action with this command is to put Jorge on belay immediately. “On Belay”

Jorge can now prepare to climb, secure in the knowledge that he is belayed from above. When he is ready to climb, he can inform his belayer with a simple, “Climbing!” A reply of, “Climb on!” will see Jorge to the top of the pitch to rejoin his partner.

Note that in the above exchange, Jorge does not query Maria as to whether he is on belay. There is no need as Maria will put Jorge on belay in response to the command of, “That’s me.” Further, Jorge may not be able to see Maria as she concludes her lead. Consequently, he will likely not know for sure when Maria has established an anchor and is ready to belay. In the best case, voicing, “On belay?!” will not elicit a call to action from Maria other than to say “No, not yet,” unless Jorge happens to pick just the right moment to ask. Asking if he is on belay simply introduces unnecessary, informal communication. In the worst case, shouting, “On belay?!” may be misunderstood as “Off belay!” Maria is likely to find this rather alarming if she has yet to complete her lead.

Scenario 3: Communicating without Commands

It is possible for a climbing party to communicate unambiguously without the use of verbal commands, thereby eliminating the potential for poor verbal communication or miscommunication. Provided the party can agree up on a system in advance, this is readily achieved. Let’s revisit the example in scenario 2 to see this in action.

Maria reaches the top of the pitch and secures herself to the anchor. Because they suspected the possibility of poor communication, Jorge and Maria agreed in advance to use only the necessary formal verbal commands. As Maria is secured to the anchor, she shouts, “Off belay!”

Unfortunately, Jorge is unable to hear this command. However, he knows that there are only two reasons that he might need to feed rope to the leader. Either Maria is still leading, or she has arrived at the belay stance and is pulling up excess rope. Since Jorge is unsure which is the case, he simply continues belaying until he reaches his end of the rope. As he did not hear Maria issue the “off belay” command, he has no reason to affirm this command. Instead, he skips this and simply proceeds to the next command, “Maria, that’s me!” He then removes his belay device from the rope.

Maria has pulled the rope until it is tensioned and thinks she hears Jorge shout a command to her, but she’s not positive. Regardless, her next step is clear: put Jorge on belay. She does so promptly and shouts, “On Belay!”

Meanwhile, down below, Jorge is diligently waiting to climb. Prior to starting the climb, Maria and Jorge agreed to a 30- second waiting period. After shouting, “Maria, that’s me!” Jorge waits 30 seconds and then removes himself from the anchor to begin climbing. He does this knowing that Maria will promptly put him on belay after the rope is tensioned, a task that should take no more than 30 seconds. Jorge and Maria could have agreed to any amount of time they felt appropriate; again the prior agreement is the important thing.

After the agreed upon amount of time, Jorge bellows, “Climbing!” and makes a couple moves. He has one last chance to make sure that he is on some form of belay. He’s making sure the rope is travelling up, in the characteristic progression of a belay cycle. In this sequence, Jorge and Maria have accepted that it might also be possible that Maria is not actually belaying. It is possible that she is still leading, and the team is now accidentally simul-climbing. Even though it’s scary and hopefully avoidable, Jorge and Maria appreciate that Jorge will have to climb in that scenario, even if he’s not on belay. What choice does he have?

Meanwhile, back at the top of the pitch, Maria cannot hear Jorge, but she can feel the slack in the rope he generates by climbing. She pulls the rope through the belay system and after a few feet of movement is sure Jorge must be climbing. As a confirmation, she yells, “Climb on!”

Troubleshooting Communication Challenges

Select belay stances and pitch lengths that enable communication, when feasible.

Occasionally, verbal communication is challenging or impossible. This happens most often on multipitch routes and can result from many factors, including a pitch that traverses around a corner or crosses a ridgeline, high winds, or stretching or linking pitches. The best strategy for these situations is simply prevention. Whenever possible, select stances that enable good verbal communication, or even visual communication if possible. Research the route thoroughly to know when your partner might be out of touch. Consider belaying at an appropriate stance even if the guidebook does not indicate the stance as a typical belay point.

This climbing team could have chosen to belay an any number of places.  The huge river gorge, the imposing rough, and the presence of other climbing parties nearby compelled the party to shorten the pitch-length and optimize communication.

The conventional wisdom is that stretching the rope and linking pitches results in a faster ascent as there are fewer belay transitions to be made. However, 15 minutes wasted shouting to a partner 200 or more feet distant certainly bears a greater time cost than two or even three efficient belay transitions.

Visual communication is helpful when verbal commands are inaudible.

Unfortunately, sometimes poor verbal communication simply cannot be prevented. This leaves a few options for alternative communication systems. A visual command system is one such solution. Such a system needs to be established in advance, but can be effective provided that appropriate belay stances are selected. Most often, a negative and affirmative command are all that is needed. For example, when the leader reaches the top of the pitch, she secures herself, then leans out to look down at her belayer and makes a slashing motion across her throat, indicating, “Off belay.” When the belayer has removed the belay device from the rope, he returns the signal. When the leader has put the follower on belay, she leans out and gives a thumbs-up signal straight overhead, indicating, “On belay.”

Beware of Rope Tugs.

A more common approach is a system of rope tugs used by the leader to communicate with the follower when she is off belay. Unfortunately, any system relying on rope tugs introduces significant ambiguity and the potential for miscommunication. For example, the climbing party may agree that three rope tugs from the leader means, “Off belay.” However, the leader might also issue three similar feeling rope tugs as a result of a potentially stuck rope or simple rope drag. If the belayer interprets this as a call to action, though, the leader may find herself unintentionally off belay for the remainder of the pitch.

Many climbing parties enjoy success with the rope tug technique, and their success usually hinges on a smoothly executed rope line, and a discipline avoidance of any rope movement that could be interrupted as a tug.

A second rope can be a communication tool too.

When climbing with two ropes, whether half ropes, a lead line and tag line, or as a party of three, the leader can unambiguously communicate the “off belay” command. Upon securing herself to the anchor, the leader’s next step is to pull up the ropes. By pulling up the trailing line first (or only one of the half ropes), the leader can clearly indicate that she is stopped at the belay stance as the lead rope is not moving.  

Just like the rope tugs, there can be opportunities for ambiguity here.  It helps for the climbing teams to consciously avoid these signals.  If the isolated movement of one of two ropes is agreed to be an "Off Belay" signal, a leader should not move that rope independently unless she is off belay.

Radios, Cell Phones, and Technology

FRS radios are another option and can ease communication considerably over long distances or in poor conditions. However, radios have a number of drawbacks, including weight and costs. Further, radio communication quality varies, both in transmission clarity and range. Additionally, radios rely on battery power, yielding an additional battery to manage. Should batteries die, over- reliance on radios may also leave a party ill-prepared to use an alternative form of communication. Despite these costs, radios can be effective and beneficial in appropriate contexts, such as multi-party climbing, expeditionary climbing, and complex ski descents. Similarly cell phones and text messages have a comparable potential and drawbacks. These technologies all present the same conclusion to a climbing team: do not rely too heavily on technology. Climbers have been communicating quite effectively without these technologies, and those traditional communications skills have value.

The Prescription — April 2022

Ground Fall | Rappel Failure

The Apron, Squamish, British Columbia

On the afternoon of September 3, 2021, Dany Dalpe (29) suffered a 200-foot ground fall from several pitches up on The Apron in Squamish. At the time, Dalpe was a climber with five years of experience. Though he consistently climbed 5.13 sport routes, his multi-pitch experience was limited to two years, mainly on bolted routes around Squamish. His partner (female, 29) was a beginner climber using borrowed gear. This was her first multi-pitch outing.

Around 12:30 p.m. the pair started up Born Again, a link-up combining sections of established routes with new pitches to create “the best protected 5.10 on the Apron.” Its copious protection, bolted belays, and generally forgiving angle made it a fine choice given the team’s limited experience.

To avoid a party climbing above, Dalpe decided to traverse left near the end of the second pitch. After joining Dream On, he found the climbing changed character. The next pitch was less forgiving and had only one protection bolt. At the top of his third lead, Dalpe recalls thinking, “This was not the day I had in mind.” The climbing above appeared even more demanding. “I looked up the next pitch and decided it was not worth it.”

At 1:30 p.m., his climbing partner arrived at the belay, and Dalpe told her they would be descending from there. The partner carried a traditional belay/rappel device, though she was not experienced enough to rappel. Dalpe planned to use his Grigri to lower her and then make a single-line rappel, using her weight at the opposite end of the rope as a counterweight anchor. He untied his partner, threaded the rope end through the rappel rings, retied her, and then used his Grigri to lower her to a prominent ledge. Once there, she traversed to a tree anchor and connected to it with a personal anchor system (PAS). Before lowering her, Dalpe said to his partner, “Go to the tree anchor, clip in, and do nothing.”

Dalpe set his Grigri up to rappel and started down the single strand. Halfway to the tree anchor, the rope became suddenly unweighted and Dalpe fell. He recalls, “I was tumbling and everything went black. Then I hit something…and went black. I hit something again…black. I hit another thing…black. I was probably screaming for five seconds.”

While falling, the rope through Dalpe’s Grigri went slack and, “I saw the rope swirling orange and I kept asking, ‘When am I gonna stop?’ ”

Dalpe hit the ground, rolled a distance, and came to rest at a tree. Climbers approaching the cliff rushed up to help. One called for an ambulance at 1:45 p.m. Another team that was on Born Again rappelled to Dalpe’s partner and lowered her to the ground. At 3:45 p.m., Dalpe was transported by ambulance to the hospital.

He escaped with relatively minor injuries considering his 200-foot tumble (He was not wearing a helmet.) He suffered a broken sternum, two broken bones in the right foot, plus multiple abrasions to his scapula and back of his head.  He spent one month on a couch, and four months later he was climbing 5.13 again. (Sources: Interview with Dany Dalpe and report from British Columbia Emergency Health Services.)

Analysis

It appears the rappel failed when Dalpe’s partner somehow managed to untie her knot as he rappelled the single strand. Later, her half-tied figure-8 was discovered to be cinched tight; her end of the rope with the half-tied knot had pulled through the rappel rings—no doubt slowing Dalpe as he tumbled toward the ground. It seems likely she began to untie as soon as she clipped into the anchor, and that some element of the system temporarily held Dalpe’s weight until he had already committed to the rappel.

Dany Dalpe, on the road to recovery.

Counterweight systems—simul-rappelling, counter-ascending, or the descent method chosen by Dalpe in this incident—are for experts only. (In fact, accidents involving such systems have claimed even very experienced climbers.) The entire team needs to understand the necessity and process of maintaining a closed system until both parties are on the ground or securely anchored. Given his partner’s limited experience, Dalpe could have made better choices involving the route, equipment, and rappel method.

The transition from single-pitch sport to multi-pitch—even on a mostly bolted climb with solid chain anchors—presents many challenges. First was equipment. This pair was equipped with a single rope and only one belay/rappel device, which necessitated a complex counterweighted rappel when they decided to bail. Another issue was experience. Dalpe’s partner, through no fault of her own, was clearly in over her head.

Dalpe’s physical climbing ability might have contributed indirectly to the accident. Climbing 5.13 after only a few years is an empowering—and often misleading—experience. In a multi-pitch or trad environment, a metric like a sport climbing grade is an inadequate substitute for proper tools, training, and experience. To his credit, Dalpe chose to descend when he recognized they were over their head on this long route. It takes years of practice to develop the skills and judgment to safely lead an inexperienced partner up a multi-pitch climb. (Source: The Editors.)

Ancient Art, Fisher Towers, Utah

Mo Leuthauser, a climber from Colorado, was starting the last pitch of the Stolen Chimney route on Ancient Art, the spiraling sandstone formation in the Fisher Towers of Utah, when she noticed a soft spot on one of her harness gear loops. She mentioned it to her partner but kept climbing. As she was being lowered from the top of the tower, “I heard a pop and saw my cams and nuts fly off the left side of my harness and hurl hundreds of feet down the tower, toward hikers below. I screamed ‘rock’ as loud as I possibly could, and luckily the hikers were able to get out of the way in time.  No one was hit or injured.”

Leuthauser was using an all-around harness that was about four years old. Although harnesses generally are safe to use for considerably longer (depending on the amount and style of climbing you do), this is a good reminder to inspect all the components of critical gear regularly for wear or damage. Dropping cams this way not only creates a hazard for anyone below, it also could be very expensive!

The Prescription - February 2021

STRANDED – STUCK RAPPEL ROPES

CASTLETON TOWER, UTAH

Just after sunset on December 4, two male climbers (ages 32 and 36) called 911 to report they were stranded halfway down 400-foot Castleton Tower because their rappel ropes had become stuck. Starting near sunrise, the pair had climbed the classic Kor-Ingalls Route (5.9) on the tower’s south side. They topped out later than expected, with about an hour and a half of daylight left.

Armed with guidebook photos and online beta, they planned to descend via the standard North Face rappels. The two saw a beefy new anchor on top of the northwest corner of the tower and decided this must be the first rappel anchor. Tying two 70-meter ropes together, the first rappeller descended about 200 feet and spotted a bolted anchor 25 feet to his right, with no other suitable anchor before the ends of the ropes. No longer in voice contact with his partner, he ascended a short distance and moved right to reach the bolted anchor. It appeared that one more double-rope rappel would get them to the ground. Once both climbers reached the mid-face anchor, they attempted to pull the ropes. Despite applying full body weight to the pull line, they could not get the ropes to budge.

Contemplating ascending the stuck rope, the climbers realized the other strand had swung out of reach across a blank face. The climbers agreed that recovering the other strand was not safe or practical, nor was climbing the unknown chimney above them in the dark. The climbers were aware the temperature was expected to drop to 15°F overnight, so they made the call for a rescue. They were prepared with a headlamp, warm jackets, hand warmers, and an emergency bivy sack.

A team of three rescuers from Grand County Search and Rescue was transported to the summit via helicopter. One rescuer rappelled to the subjects around 9 p.m. and assisted them in rappelling to the base of the tower. 

ANALYSIS

The rescuers discovered the climbers had mistakenly rappelled from an anchor used to rig a 500-meter highline (slackline) over to the neighboring Rectory formation. Instead of rappelling the North Face, as planned, the climbers had ended up on the less-traveled West Face Route (5.11). Because the highline anchors were not intended for rappelling, friction made it impossible for the climbers to pull their ropes.

Upon reflection, the climbing party identified a number of decisions that could have prevented this misadventure. Had they abandoned the climb and rappelled the Kor-Ingalls Route earlier, they probably would have been down before sunset. Even after finishing the route, heading back down the Kor-Ingalls would have had the advantage of familiarity with the anchor stations rather than rappelling into unknown territory. Lastly, while the highline anchor is quite visible atop the tower, its configuration, set back from the cliff edge with very short chain links, indicates it is not appropriate for a rappel. The climbers may have felt rushed with the setting sun and dropping temperatures, but if they had looked more thoroughly, they likely would have found the North Face rappel station, about 15 feet away . This anchor’s bolts have three or four feet of chain that extend over the edge and attach to large rappel rings, making for an easy pull. (Sources: The climbers, Grand County Search and Rescue, and the Editors.) 

The Hazards of Highline Anchors

As highlines, BASE jumps, and space nets grow in popularity, the number of nonclimbing bolted anchors is on the rise at certain climbing areas, and rescues like this are becoming more prevalent. In fact, this is the second stranding in five years resulting from an attempted rappel using the same highline anchor on Castleton Tower. Two very similar incidents were reported in ANAC 2019: one at Smith Rock, Oregon, and one in Clear Creek Canyon, Colorado.

To avoid mistakenly using an anchor that’s not intended for rappelling, study published descriptions of anchor locations carefully. If an anchor does not appear to be set up properly for rappelling—especially when it’s on a very popular formation like Castleton Tower—look around and consider the options before committing to the rappel. 

After word got out about these stranded climbers on Castleton Tower, a local guide removed the chain links from the highline anchor to discourage future incidents. (The links can easily be reinstalled to rig the highline to the Rectory.) Plans are in the works to attach plaques identifying the bolts as a highline anchor.

THE SHARP END: A SKIER’S SCARY SLIDE ON MT. HOOD

Last June, a 25-year-old skier had just begun his descent from Mt. Hood’s summit when he missed a turn and started sliding. Waiting at the bottom was a fumarole: an opening in the volcano’s icy surface that emits steam and noxious gases. In episode 61 of the Sharp End, this skier tells host Ashley Saupe about his accident and ensuing rescue. The Sharp End podcast is sponsored by the American Alpine Club.

Climbers and Fumaroles

Fumarole incidents on Oregon’s Mt. Hood are not uncommon. These dangerous volcanic vents form in the run-out zone below several of Hood’s most popular summit routes. In December 2020, another skier fell through a thin bridge over a fumarole on Mt. Hood. Like the skier in this month’s Sharp End, she was traveling alone, and she was fortunate that bystanders quickly came to her aid. Although traditional crevasse hazard is seldom an issue on Hood’s normal routes, solo climbers and skiers should be acutely aware of fumarole dangers, how to identify them, and their likely locations. For more on Mt. Hood’s common accident types, see “Danger Zones” in ANAC 2018.

OMG! THIS BOLT IS LOOSE!

According to the New River Alliance of Climbers (NRAC) in West Virginia, 75 percent of the “bad bolt” reports it receives are simple cases of loose nuts that could be tightened easily. This fun, one-minute video from the NRAC offers a quick breakdown of what to do when you encounter a loose bolt—which can be tightened and which should be reported to your local climbing organization or BadBolts.com.

Favorite type of climbing?

I love single-pitch sport—there's just something about the mental and physical challenge of finding my way up the rock, and that's where I push my ability the furthest. But the overall experience of alpine climbing—the isolation, the mountain views, the promise of adventure—is hard to beat.

How did you first become interested in Accidents?

When I was first learning how to climb, I had no real sense of what could go wrong. As a way to educate and caution me, a friend pointed me to the Accidents publication, and it became a wonderful learning tool. Reading about climbing mishaps and poring over the analysis of why these things happened drove home the seriousness of the sport and instilled a deep appreciation for safety. Editing Accidents and diving into the details of each incident constantly reminds me of these things and has deepened my understanding of techniques.

Personal scariest incident?

I was warming up on a sport route in the Tieton River area, west of Yakima, on a sweltering summer day, and the climb had an extremely high first bolt. As I went to move my left hand, a rock fell from the cliff above and startled me. I lost my grip and fell 22 feet, landing upright and shattering the tibia and fibula in my left leg. I was only falling for seconds, but it felt like the world slowed down as my mind frantically tried to process what was happening and how I could protect myself. So terrifying!
