Two Avalanches – Rope Cut, Anchor Unclipped

We know that many people don’t read every single report in Accidents—particularly ones that are far from home and more than three pages long. But we want to call your attention to the story highlighted here, both for the lessons it imparts and for the drama of the events—fortunately they ended without a fatality or very serious injuries. A condensed outline follows. We highly recommend reading the full report, starting on page 20 of this year’s book or at this page on our publications website.

On April 15, Fallon Connolly, 26, and Simon Frez-Albrecht, age 28 (both experienced climbers), started up the nearly 6,000-foot north face of Pioneer Peak, northeast of Anchorage, at 5:45 a.m. It had been 37°F at the car. Near the second ice band on the long snow and ice route, about 4,000 feet above the start, Fallon observed signs of what appeared to be fairly recent avalanches on the gully walls. Simon was about 50 feet ahead of Fallon and had nearly reached a position to anchor for the next pitch when he noticed a very small wet loose avalanche come tumbling over the ice above. He yelled down to warn Fallon. Simon was standing to one side of the gully, and it didn’t hit him, but it all washed directly over Fallon; she planted both tools firmly and put her head down to let the snow pass. They estimated the flow lasted 60 seconds.

After the flow stopped, Fallon continued up to where Simon was waiting and they moved together perhaps 50 feet up and to the opposite side of the gully, where there were some obvious cracks in the rock. Here they built an anchor and, given what they had observed, prepared to descend from this point. Simon bounce-tested their bail anchor and then set up their brand-new 7.8mm ropes (pink and green) and threaded them through his device for a rappel. Fallon also pre-rigged her device on the rappel ropes. A number 2 Camalot they had placed temporarily was clipped to the ropes as backup, with a non-locker on a 60cm sling. Fallon remained clipped to the cord masterpoint in the anchor with a locking carabiner as Simon began to rappel. When Simon was about halfway down, Fallon yelled to warn him about another avalanche coming over the ice pitch above.

What followed was an extraordinary “series of unfortunate events”:

Brand-new rope cut during this incident.

• Fallon was knocked off her feet by the slide and left hanging from her tether clipped to the anchor. Her gloves and glasses disappeared.

• Their pink rappel rope broke (likely cut against a sharp edge of rock), but the knot joining the ropes jammed in Fallon’s pre-rigged rappel device, keeping the other rope attached to her and thus to the anchor.

• Simon was pummeled by avalanche debris for one to three minutes. Only a tangle in the green rope kept him from being pulled to the end of the rope by the debris.

• As the slide ended, Fallon stood up at the anchor. Before she could reinforce her tether or anchor the green rope, a second avalanche rumbled over the ice above. This time, Fallon was pulled from the anchor and tumbled down the slope.

Damage to Fallon’s harness when she was hit by avalanches at the rappel stance on Pioneer Peak. The harness likely would have sustained many kilonewtons of force to be damaged this way, yet both it and the anchor held.

• Simon heard and saw the second slide coming and was able to shelter behind a rock outcrop, yet the debris plucked him from this stance and he fell another 100 feet down the snow gully. Fallon slid and tumbled a total of 300 to 400 feet.

Very fortunately, neither climber was buried, swept all the way down the mountain, or seriously injured, and they were able to self-rescue to the road.

In his analysis of the incident, Simon outlined numerous important but subtle clues they missed when they decided to climb this route on a relatively warm day. “We felt we had pieced together enough information to make an informed decision,” he wrote. “I suspected the shed cycle had already happened in the previous warm, sunny days, so there wouldn’t be a significant amount of loose/available snow left on the mountain to slide onto us. I didn’t consider that the freezing at night had been enough to keep the snow locked in place, poised above us.

“Probably the single most obvious clue we missed,” he continued, “was that it had stayed cloudy the night before our climb, preventing the radiant cooling that had dropped night time temps in the previous days. This kept the snowpack wet and near the tipping point when the weak sun struck the face for a couple of hours through the clouds.”

Ten days after the accident, in colder conditions, Simon climbed back to their anchor to try to determine what had happened. He found a sharp edge where the pink rope, oscillating under load during the slide, likely had cut. However, most of the anchor was intact. Fallon’s tether and locking carabiner, which had fallen with her during the second avalanche, also were undamaged. “Why had she come unclipped from the anchor?” Simon wondered. “The only conclusion we can draw is that the screw-gate locker with which Fallon clipped her tether to the master point must have jiggled to the unlocked position during the first avalanche. Then, when she unweighted the tether, the locker must have shifted into a position where it could unclip itself when the second avalanche pushed her back onto her tether.”

Simon might have slid all the way down the mountain during the first avalanche, when the pink rope broke, except for one extra step the two took while preparing to rappel. “Over the last year or two, I have been making a conscious effort to increase my safety margin while climbing,” Simon wrote. “This includes tying knots in the ends of ropes during rappels, using a rappel backup, and using autolocking carabiners and assisted braking belay devices more often. I had recently been toying with pre-rigging rappel devices as well, but was not doing this consistently. For whatever reason, this was one of those times we pre-rigged Fallon’s belay device on the rope, and by snagging the knot joining the ropes after our pink rope cut, it happened to keep me alive.”

Again, we encourage you to read the full report in ANAC 2021 or find it here. We’re grateful to climbers like Simon and Fallon who choose to share such stories, which can be painful or even embarrassing to recount. They teach us that the little things sometimes can make all the difference.

ROCKFALL AND RESCUE IN ZION NATIONAL PARK

Aaron, 42, and Ian, 16 are a father-son team of adventurous climbers from Tucson, Arizona. In June 2021, with lots of exploratory climbing experience under their belts, they headed to Zion National Park to attempt a relatively obscure route on a cliff informally known as Mt. Greer. On the 12th pitch, gunning for the top of the formation, Aaron was leading a gully and chimney system when the rock under his feet crumbled, sending sandstone blocks tumbling down the gully toward his son. Listen to the new Sharp End podcast to hear all about how they got into this predicament—and how they got out.

KNOW THE ROPES: SUMMER AVALANCHES

Spring and Summer Hazards for Mountaineers

It’s springtime and that means snow slopes have stabilized and avalanche danger is a thing of the past, right? Not so fast. For mountaineers and skiers, avalanche season continues well into summer. And in the warmer months, mountaineers account for the large majority of fatal avalanche incidents.

For the 2020 edition of Accidents in North American Climbing, Seattle-based ski mountaineering guide and avalanche forecaster Matt Schonwald wrote an in-depth “Know the Ropes” article about mountaineering avalanches. At the top of his article, Matt described the problems with these avalanches and the reasons many climbers are less than fully prepared:

“Although a large majority of avalanche fatalities occur in the winter months, avalanches are not uncommon in the long days of late spring and early summer. According to the national database compiled by the Colorado Avalanche Information Center (CAIC), since 1951 in the United States, 39 out of 44 avalanche fatalities in June and 31 out of 43 in May have involved climbers.

“Most backcountry skiers and winter mountaineers in avalanche-prone areas have some knowledge of the hazards and carry basic avalanche safety equipment, such as transceivers, probes, and shovels…. But preparation for avalanche hazards in the spring and summer mountaineering season is not as widespread or systematic. Most avalanche training is skewed toward winter travelers, and many avalanches that affect mountaineers occur in terrain not covered by avalanche forecasts or after avalanche centers have shut down for the season.

“At the same time, the consequences of an avalanche are at least as great for mountaineers in spring and summer as they are during the winter months. As the winter snowpack melts back, additional hazards are exposed. Cliffs, narrow couloirs, exposed crevasses or boulder fields, and other terrain traps make an encounter with even a small avalanche potentially fatal.

“Mountains big and small possess the potential to bury or injure you with the right combination of unstable snow, terrain, and a trigger—often someone in your party. It’s not only important to recognize these hazards but also to have the discipline to respect the problem and choose another route or wait till the risk decreases. In preparing to enter avalanche terrain, the mountaineer must be focused more on avoiding avalanches than on surviving one, and that is the focus of this article.”

Matt’s story goes on to describe how to recognize avalanche hazards in mountaineering settings and how to plan climbs to minimize the hazards. If you’re contemplating a climbing or skiing trip in snowy mountains this season, this article is essential reading.

FROM THE ARCHIVE: A Real-World Example From Mt. Hood

In the 1999 edition of ANAC, we described a tragic incident on Mt. Hood on May 31, 1998. An avalanche struck a team attempting the West Crater Rim route at 10:05 a.m. and swept down about 1,250 feet. One climber was killed in the slide and two others seriously injured; the leader of the group, on a separate rope team, also was injured. The party had headed up the mountain despite one to two feet of new snow in the past week, a “high avalanche hazard” warning posted by the U.S. Forest Service, and signs of recent avalanche activity along their route.

According to the Mt. Hood climbing ranger, most of the people on the mountain that day in late May did not carry avalanche transceivers. “Some of these climbers later remarked that they hadn’t considered avalanches to be a problem, as it was late in the season and it was such a beautiful day,” the report says. “But in fact, a secondary maximum in monthly Northwest avalanche fatalities occurs in May, similar to the mid-winter Northwest maximums.”

IT’S SPRINGTIME! HEADS UP!

Avalanches aren’t the only hazards that trend upward in springtime: Rockfall and loose holds become more frequent at many cliffs in the spring, as the freeze-thaw cycle and heavy precipitation prepares missiles for launching.

Last May, a climber experienced this the hard way during the fifth-class approach to Break on Through at Moore’s Wall, North Carolina. Two weeks of heavy rain had loosened some big holds, and this climber found one of them. His report will be published in ANAC 2021, but you can read it now at the AAC’s publications website.

If you choose not to wear a helmet for shorter climbs, such as sport routes, consider changing this habit for spring and early summer climbs. In addition to the hazards mentioned above, thunderstorms frequently send volleys of rock over cliffs, threatening climbers and belayers alike. Rockfall also may impact fixed gear and anchors: Check before you trust.

Ice Climbers & Avalanches

It’s Time to Take this risk more seriously

By Grant Statham

Every winter, ice climbers are caught—and sometimes killed—by avalanches. Even small avalanches can be deadly when they get funneled into the narrow gullies where ice climbs form. So understanding the avalanche conditions and carrying rescue gear when climbing is essential for many climbs.

Yet despite this reality, climbers have been slow to embrace basic avalanche safety practices, even when they always use avalanche gear when backcountry skiing. This contradiction makes no sense, and it’s high time for a paradigm shift.

Once you’ve determined if your ice route is formed, your next move should be to figure out whether it’s threatened by avalanches. Any steep snow slopes on the approach, the route, above the route, or on the descent have the potential to release an avalanche.

If your route is threatened by avalanches, then you need to know more. Is the climb located in a gully with avalanche start zones overhead? Will you be climbing through snow slopes above cliffs? How about the approach—will you be walking under avalanche paths or kicking steps up a 40° slope to reach the base? How hard is the route—can you climb fast or will you be exposed to avalanches for hours? What does the local avalanche forecast say? You need to answer all of these questions before going climbing.

AVALANCHE RISK

Avalanche risk in ice climbing has three main ingredients: 1) enough snow to produce an avalanche, 2) avalanche-prone terrain, and 3) climbers exposed to this hazard. Remove any one of these elements and you’ve eliminated the avalanche risk.

But while eliminating avalanche risk ensures safety, it won’t get you up the routes on your hit list that are subject to avalanche hazard. For this, you’ll need to manage the risk by assessing its individual elements and understanding how they affect you and your partner.

SNOW

The best indicator of unstable snow is avalanche activity. Both slab avalanches and sluffs are threats to ice climbers, because it doesn’t take much to knock you off your front points. If avalanches are occurring near your route, then it’s safe to assume the snow on your route is also unstable. Here are the big three factors:

(1) Precipitation: new snow and especially rain can overload the snowpack

(2) Wind can move snow at 10 times the snowfall rate and create locally deep slabs

(3) Temperature: warming trends, inversions, and temps over 0°C (32°F) produce avalanches

TERRAIN

Minimize your exposure by positioning belays out of avalanche terrain or in protected locations, moving together when you can, moving one at a time when necessary, belaying across exposed slopes, and spending no unnecessary time exposed to avalanches. These are the strategies that keep experienced climbers alive. Here are the terrain basics to keep front of mind:

(1) Slope angle: the prime angle for slab avalanches is 30° to 45°

(2) Aspect: there are big differences between routes in the shade and in the sun

(3) Elevation: snow depth increases with elevation, so be aware of conditions overhead

(4) Terrain traps: ice climbs are often in or above terrain features that increase consequences (cliffs, gullies, creeks, etc.)

PEOPLE

Debris from several slides that trapped two climbers on a route in Santaquin Canyon, Utah, in February 2019. The avalanche hazard was rated low at the elevation of the climb but more dangerous high up the mountain, where these slides originated. Read the report here.

For risk to exist, something must be “at risk,” and in climbing this is people, deliberately exposing themselves to avalanche hazard. All people are fallible, and human factors are well-recognized as a major contributor to avalanche accidents. Here are some considerations:

(1) Partners: climb with people you trust and who share your values around risk

(2) Decision-making: trust your instincts and bail if it doesn’t feel right

(3) Trophy hunting: don’t obsess over one climb; have options and let the conditions determine your route

(4) Group size and speed: keep your team small and move efficiently

PUBLIC AVALANCHE FORECASTS

An excellent source of information on local conditions is the public avalanche forecast, found at avalanche.ca in Canada and avalanche.org in the USA. Locals watch the forecast regularly to stay abreast of conditions; start checking it early to get a sense of the snowpack.

Don’t climb in avalanche terrain unless the danger rating is Low or Moderate. When it’s Considerable, avalanches are likely, so now you need to know specific details about the route and what might trigger an avalanche there. If you don’t understand this, then don’t climb there. High and Extreme are obvious—stay out of avalanche terrain.

NATURAL RELEASES AND CLIMBER TRIGGERED AVALANCHES

Many ice climbs form directly beneath large avalanche slopes. To climb these routes, you need to determine whether a natural avalanche will release while you’re there. This is difficult, but the avalanche forecast, weather forecast, and ridge-top weather stations (accessible online) will provide some of the information you need. Always remember that snow depth, wind effect, and air temperature will be much different high above your climb, so don’t be lulled into complacency by snow conditions near your route.

Climbing steep snow is usually part of ice climbing, and this can lead to triggering a slope yourself. Whenever possible, go around snow slopes or cross them as high as you can to reduce the amount of snow above you. If you have to climb directly up the middle of a big slope, the best tactic is to evaluate smaller, safer slopes of similar character to get sense of conditions. Then consider spacing out, going one at a time, or belaying, even if the slope is small but the consequences are catastrophic.

CARRY AVALANCHE RESCUE GEAR

If you’re climbing and exposed to avalanche risk, then you should use avalanche rescue gear. If someone gets buried, you have about ten minutes to find them, dig them out, and clear their airway before they asphyxiate. Each member of the team should carry an avalanche transceiver, probe, and shovel. Nobody likes extra weight, so be thoughtful about when and where you carry the gear—plan it out like you plan your rack. Do you only need it for the approach or for the whole route? Maybe take one shovel up the route instead of two. What about the descent?

Even if you’re climbing a route where you think an avalanche would be unsurvivable, somebody will still want you back, which means SAR teams will be searching for you. Wearing a transceiver and using clothing equipped with the Recco system does everyone a favor by making you searchable.

RISK AND REWARD

Good avalanche skills are part of being a solid alpinist and waterfall ice climber. While climbing a great route feels awesome, climbing it in good style and doing everything you can to reduce your risk feels even better. Adding risk without additional benefit is pointless, so learn about avalanches, carry the gear, and respond to the ever-changing conditions.

THE SHARP END: A CREVASSE FALL IN THE TETONS!

View fullsize

Tyler Willis and a friend were descending from a successful ascent of Mt. Owen in Grand Teton National Park. It was late in the day when they reached the Teton Glacier, which they had crossed without a problem early that morning. Just a few steps later, Tyler plunged into a hidden crevasse, an extremely rare accident for the Tetons. By the time climbers pulled him to the surface, he was hypothermic, and it wasn't until the next day that rangers could helicopter him to safety. Hear all about it in Episode 58 of the Sharp End (link below).

An accident like this illustrates the importance of recognizing and treating the symptoms of hypothermia, which may develop even on a sunny day in August. A useful reference for climbers and clinicians alike is the Wilderness Medical Society’s updated guidelines assessment and treatment of hypothermia patients. The article and several downloadable field guides (like the one shown above) are available at this link.

AVOID INJURIES DURING WINTER TRAINING

Photo: Alton Richardson

Dr. Volker Schöffl is one of the world’s foremost authorities on climbing injuries. The German professor and physician is co-author of One Move Too Many: How to Understand the Injuries and Overuse Syndromes of Rock Climbing (Sharp End Publishing, 2016). This year, he and co-authors Dicki Korb and Patrick Matros released a new work describing complementary training to avoid injuries. The 94-page book is packed with tips and specific exercises, and it’s available as a free download! We decided to ask Schöffl for some training advice for Prescription readers.

We’re headed into winter and lots more indoor climbing. What are the most important things climbers can do to prevent injuries during the months of indoor training?

Do not overdo it early on, and build up strength gradually through the winter. Motivation is high, as everyone wants to be better next season. Don’t forget, you have to endure a couple months of training, and you should pace yourself. Increase the load gradually and this will help you to avoid overuse injuries in November.

What are the most common areas of injury for climbers heading indoors? 

This really depends on the type of training you are doing. In pure strength training, simple overload leads to finger stress and tenosynovitis (inflammation of the tendon sheath). In indoor bouldering, especially with dynamic problems, injuries from falls onto the lower extremity are most common. Overuse and over training in indoor climbing also affects the shoulders and elbows.

Any recommendations for avoiding these common injuries?

A proper warm-up will help to reduce both injury incidence and severity. Stretching itself is not ideal as a warm-up, as it reduces muscle tension (stretching is more appropriate for cool-down after a session). Warm-up should consist of some general exercise and include finger specific exercises (e.g., therapy putty, softball squeezes, or plain finger movements). You can find some examples in One Move Too Many. Climbers should also focus on adjunct compensatory training (ACT)—exercises that counteract the specific stressors of climbing. We just released our ACT program, which is a free pdf booklet, accessible through www.act.clinic. After this general warm-up phase continue into some easy climbing and gradually increase stress/difficulty to a peak approximately 30 minutes into the climbing session.

Can you tell us more about ACT and its importance for overall climbing performance?

Climbing, as with many other sports, stresses the body in uniform patterns, leading to strength in certain muscle groups and to neglect in others. These imbalances lead to posture deficiencies and poor movement patterns. ACT focuses on training the neglected muscle slings (muscle, fascia, and ligaments) and innervation patterns within their specific range of motion, building up posture and core strength as well as balancing the athletic build of the body. In order to withstand climbing specific training over time and to prevent associated injuries, the antagonists and neglected muscle groups must be addressed. This is where ACT comes into play.

MEET THE RESCUERS

Doug McCall, President of Mountain Rescue Association (MRA) and member of Seattle Mountain Rescue

Years volunteering with your team: 12

Home Crag:  Exit 38, Deception Crags/Far Side Wall

Favorite type of climbing: Single-pitch sport. The crags near me offer a wide range of grades that allow me to climb with a wide variety of people. I love bringing new people to the crag and letting them try outdoor climbing for the first time. I also love challenging myself with friends who climb above my abilities.

How did you first become interested in search and rescue?

I was a volunteer firefighter at our local department when one of the other volunteers began talking about climbing and then later about Seattle Mountain Rescue (SMR). He had been a member of SMR for about 15 to 20 years and recommended that I apply. I was excited about the opportunity to combine my passion for the outdoors with the medical skills I had learned through the fire department. I was accepted into SMR in February 2008.

Why do you think accident reporting is important?

Learning from others’ mistakes is a powerful way that humans learn from one another. While it is easy to “armchair quarterback” some scenarios, you never really know what you might do when presented with a sudden experience. Knowing what others did or didn’t do helps to frame a thought process that may help you or your climbing partner down the road.

Personal scariest “close call”?

Early in my alpine career, my climbing partner, mentor, and cousin, Doug Walker, and I were caught in a slab avalanche that swept me down a 600-foot slope and then off a 30-foot cliff. I somehow survived. The worst injury was a severe fracture around my left eye that I likely sustained from a glancing blow to a rock. While we were able to self-rescue, I have since felt compelled to try to help others during their bad day in the mountains.

Personal safety tip?

I wear a helmet when climbing. While my doctors say that I have a very thick skull, I’d rather never have to test that again. Helmets are easy and offer good protection from an unexpected slip or rock fall. Also, I always tie knots at the ends of my rope when on rappel. I’ve been on numerous recoveries where a knot would have been the difference between life and death.

What would you say to people interested in learning more about search and rescue?

I’d encourage people to find a local MRA team or a SAR team and learn more about how to become a member. MRA teams train constantly and test each other to ensure that every team can safely effect rescues in all sorts of terrain and conditions. We also operate with a safety mindset that carries over into our personal climbing.

What is your favorite thing to do when you are not climbing?

Spend time with my family. My family has been very supportive and patient with all my time spent climbing and responding to rescues. While we tend to do a lot of outdoor activities together, they have also taught me to enjoy a number of other activities. Being with family and sharing experiences with them have been the greatest joys of my life.
