What to Do If Caught in an Avalanche? 2026

If you're caught in an avalanche, the next 15 minutes decide whether you live or die. Our team has spent years studying backcountry avalanche safety reports, AIARE training materials, and survivor accounts from the Utah Avalanche Center and Avalanche Canada, and the pattern is brutally consistent: roughly 93% of buried victims recovered alive are dug out within 15 minutes, but survival drops to 20-30% by 45 minutes and approaches zero after two hours.

This guide covers what to do if caught in an avalanche, from the first split-second you hear the fracture to the moment help arrives. We've combined quick-action steps (the kind you can rehearse on a chairlift), scenario-specific advice for skiers, snowboarders, snowmobilers, and climbers, the companion rescue protocol, and the aftermath steps almost no other article covers. If you spend time in snowy mountains, read this once, then read it again.

What to Do If Caught in an Avalanche: 7 Steps That Save Lives

These seven steps are the action sequence taught by AIARE and used by Avalanche Canada. Memorize them in order. In a real slide, you will not think clearly, you will act on rehearsal.

1. Yell "avalanche" to warn your group and anchor everyone's eyes on your location.
2. Try to escape to the side off the slab at a 45-degree angle toward the edge or the toe of the debris.
3. Shed heavy gear - skis, poles, snowboard, and backpack - anything that drags you under or acts as an anchor.
4. Deploy your avalanche airbag if you carry one, the inflation can keep you near the surface.
5. Swim and fight with vigorous backstroke-style motions to stay on top of the moving snow.
6. Grab a tree, rock, or sturdy object and shelter on its downhill side if you can reach one in time.
7. Create an air pocket in front of your mouth as the flow slows, then push one arm up toward the surface as a marker.

That list is the spine of this article. Everything below it explains why each step matters, what to do if it fails, and what to do next.

Survival Odds by Time Buried

These numbers come from burial studies compiled by the Utah Avalanche Center and remain the most-cited survival statistics in avalanche education. They are the single most important fact to internalize, because they explain why the rescue clock starts the instant the snow stops moving.

Time Buried	Approximate Survival Rate
Within 15 minutes	~93%
15-45 minutes	20-30%
45 minutes to 2 hours	Drops sharply
Beyond 2 hours	Near zero without major trauma as cause of death

The drop-off is mostly about suffocation, not weight. Avalanche debris is 60-70% air, far too light to crush a human chest, but dense enough that you cannot expand your lungs to breathe fresh air. Carbon dioxide from your own exhalations builds up around your face and displaces oxygen. This is why every step below focuses on either staying on top or buying time for your partners to dig you out.

What Actually Kills Avalanche Victims

Most people assume trauma kills avalanche victims, the weight of the snow, impact with trees, suffocation under a heavy load. The reality is more specific and more actionable.

Carbon dioxide poisoning is the leading cause of death in full burials. As you breathe into a small air pocket, exhaled CO2 pools in front of your mouth and nose. After roughly 15-20 minutes in a sealed space, oxygen drops to dangerous levels and you lose consciousness.

Trauma from collisions with trees, rocks, cliffs, and the bed surface kills roughly a quarter of victims instantly or shortly after the slide. A helmet is one of the simplest survival upgrades you can buy.

Hypothermia rarely kills in the first hour, but becomes a major risk if rescue is delayed or if you are wet and exposed after partial burial.

Knowing the actual killers reframes the survival checklist. Air pocket before snow fully sets, helmet on every ride, and partner rescue under 15 minutes are the three levers that move the odds the most.

How Avalanches Work: Why Escape Is So Hard

Understanding the physics is the difference between hoping you'll be fine and actually rehearsing what to do.

Slab avalanches are the killers in roughly 90% of fatalities. A cohesive slab of snow fractures along a weak layer and slides as a single plate. Dry slab avalanches accelerate to 60-80 mph within about five seconds of fracture. From the moment you see the cracks shoot out from your skis, you have seconds, not minutes.

Loose snow avalanches (sluffs) start at a single point and fan out. They are slower, smaller, and most dangerous in steep, confined terrain where they can knock you off your feet and drag you into terrain traps like gullies, cliffs, or trees.

The burial problem. Once the snow stops moving, debris sets like concrete within minutes. Anyone who has tried to dig with their hands in avalanche debris will tell you it is closer to digging into a frozen sandcastle than into powder. This is why you cannot dig yourself out, and why companion rescue matters more than self-rescue.

Step-by-Step: How to Survive an Avalanche Heading Toward You

Each of the seven quick-action steps above deserves more detail. Read these slowly. Rehearse them mentally before every backcountry day.

Yell and Try to Escape to the Side

The instant you see cracks shoot out, hear a "whumpf," or feel the slope collapse, shout "avalanche!" Your partners need to see where you are so they can track your body as the slide carries you downslope.

Your second action is the only real escape route: try to ride or ski to the side at a 45-degree angle off the moving slab. The slab is typically a few feet to a few yards deep; escaping off its edge or toward the toe is sometimes possible in the first second or two. Anyone who has been caught describes this window as shockingly brief, more like one breath than a deliberate plan.

Shed Heavy Gear Immediately

Once you are in the flow, every piece of gear becomes either a lifesaver or a tomb. Skis attached by brakes act as anchors that drag you to the bottom of the debris. Poles pin you in place. A heavy backpack buries you deeper.

Drop your poles first, then release your ski bindings or step out of your snowboard straps. If you have a backpack with an avalanche airbag, keep it on, your airbag is your lifeline. Otherwise, shed the pack only if it is dragging you down.

Deploy Your Avalanche Airbag If You Carry One

An avalanche airbag pack is a backpack with one or two balloons that inflate in two to three seconds. By increasing your volume, it uses the principle of inverse segregation to keep you higher in the debris flow, closer to the surface.

Pull the trigger handle as soon as you are certain you are caught, not when you think you might be. Inflation takes seconds, and a deployed airbag statistically more than doubles survival odds. If your airbag fails to deploy, keep swimming and fighting.

Swim and Fight to Stay on Top

Use swimming motions, backstroke-style arm pulls and kick-style leg thrusts, to stay near the surface of the moving snow. Avalanche debris behaves more like wet concrete than powder, so the fight is exhausting. Keep your mouth closed and try to keep your head upslope.

This is the most physically demanding step and the one survivors describe as the difference between being buried a foot deep versus six feet deep. A foot-deep burial is survivable without a beacon; six feet is almost always fatal without rapid partner rescue.

Grab a Tree or Sturdy Anchor

If a tree, large rock, or cliff face is within reach, grab it and shelter on its downhill side. Trees can snap under the force of a large slide, but many survivors credit grabbing a tree with stopping them before the debris buried them fully.

Snowmobilers sometimes have enough momentum to ride out of the upper part of the slide by throttling uphill at a sharp angle. Climbers can attempt a self-arrest with an ice axe buried into the bed surface, though success is rare in deep debris.

Create an Air Pocket Before the Snow Stops

This is the single most important action in the final seconds of the slide. As the debris slows, thrust one arm and your head upward, then sweep snow away from your face with your free hand. You have only a second or two before the snow sets.

A small pocket the size of a water bottle in front of your nose and mouth is the difference between surviving 15 minutes and surviving 3 minutes. Every survivor story emphasizes this step.

Push One Arm Up Toward the Surface

Once the snow sets, push one arm straight up toward the surface. If your hand breaks the surface, your partner can see it and dig directly to you. If you cannot move, you have bought your rescuers critical seconds by giving them a target.

If your hand does not break the surface, do not waste oxygen trying to dig. Stay calm, slow your breathing, and wait for your partners to find you with a beacon and probe.

If You Get Fully Buried: How to Stay Alive Until Help Arrives

Full burial is terrifying but not hopeless if your partners have beacons, probes, and shovels. Your job is to buy them time.

Stay calm. Panic accelerates your breathing, which accelerates CO2 buildup. Slow your breathing to once every two to three seconds if you can.

Conserve oxygen. Do not yell. Do not thrash. Every wasted breath shortens the clock.

Spit to test which way is up. This is one of the few "avalanche myths" that actually has some basis. If the spit drips downward, you are roughly upright and your feet are below you. If it falls onto your face, you are upside down and your face is at the bottom of the debris. (This works only if you have enough air space to spit.)

What it feels like. Survivors describe complete darkness, total silence except for their own breathing, and the surreal sensation of being held in place by what feels like concrete. The cold is less dramatic than people expect because the snow insulates you.

Scenario-Specific Survival Tips

The seven steps apply to everyone, but the mechanics differ by activity. Use the checklist that matches your day.

If You're a Skier Caught in an Avalanche

Release your bindings as soon as you are in the flow. Ski brakes act as anchors once the snow stops, dragging you deeper. If your skis do not release, they will pin you near the toe of the debris.

Skiers have one advantage: weight distribution. A strong, athletic skier who keeps swimming has a real chance of staying on or near the surface.

If You're a Snowboarder Caught in an Avalanche

Unstrap your bindings immediately. A snowboard with one foot still attached is a heavy drag. Your stance, sideways, makes swimming motions harder than for a skier, but vigorous arm pulling and twisting can keep you oriented upslope.

Snowboarders statistically are caught less often than skiers but buried slightly deeper on average, often because they ride more aggressive terrain and have not released their board.

If You're a Snowmobiler Caught in an Avalanche

Snowmobilers are caught at a higher rate than any other user group, and many die from machine trauma. Your first action, if you have any warning, is to angle the sled upslope and gun the throttle to ride out the top of the slide. If caught, get off the machine if you can, but only if you can do so without being run over by it.

Sleds are heavy enough that they often end up at the bottom of the debris. Stay uphill of the machine if possible. Most snowmobile avalanche fatalities involve the rider being found under or beside the machine.

If You're a Climber, Hiker, or Snowshoer

Climbers can attempt an ice-axe self-arrest if caught near the top of a small slide on a firm bed surface. Plunge the axe deep and brace your body against the force. Success is rare in deep debris.

Hikers and snowshoers should ditch their poles, keep their backpacks on if they have an airbag, and shed the pack otherwise. Stay on your feet as long as possible and try to grab a tree.

Companion Rescue: How to Dig Someone Out of an Avalanche

Companion rescue is what makes the 15-minute clock survivable. If your partner is buried and you have a beacon, probe, and shovel, you can find and dig them out in time. Without those three tools, the odds collapse.

The 15-Minute Survival Rule

Industry-wide data shows roughly 93% of buried victims recovered alive are dug out within 15 minutes. This is the single most important number in avalanche safety. Everything in the rescue sequence is designed to compress the search-and-dig time to under 15 minutes.

Beacon, Probe, Shovel: The Rescue Trio

Every person in avalanche terrain carries three pieces of non-negotiable gear:

• Beacon (transceiver) - worn on your body, turned on before you leave the trailhead, in receive mode for everyone except the person searching.
• Probe - a 240-300 cm collapsible pole you assemble and push into the snow to pinpoint the buried victim.
• Shovel - a metal-bladed avalanche shovel with a collapsible handle.

For a deeper breakdown of the gear itself, see our picks for the best avalanche probes and the best avalanche shovels. Both pieces of gear are useless without practice, so get familiar with yours at home.

Performing a Beacon Search Step by Step

Switch your beacon to search mode the moment the slide stops and you confirm someone is missing. Do not take your beacon off your body.

1. Coarse search - walk in the direction of the fastest signal, watching the distance number drop.
2. Fine search - when the number is below 3.0, slow down and bracket the signal by moving in perpendicular arcs.
3. Pinpoint search - when the number is below 0.5, mark the spot with a glove or piece of gear.

If multiple people are searching, switch only one beacon to search at a time. All other beacons stay in receive mode so the searcher hears a clean signal.

Probing and Strategic Excavation

Probe in a spiral pattern from your pinpoint mark, working outward in 25 cm increments. When you get a strike, leave the probe in place; that is your digging target.

Dig downhill of the probe at an angle, not straight down. Strategic excavation removes snow from the downhill side and creates a working pit. Most rescuers underestimate how long digging takes; budget 10-15 minutes of hard labor from probe strike to uncovering the victim's face.

What If You Don't Have a Beacon or Probe

If you witness a burial and have no beacon or probe, your only realistic tool is a coarse search of the debris using visual cues: a hand sticking up, a piece of clothing, equipment on the surface. Statistically, your odds drop to single-digit percentages without electronics.

This is the strongest argument for never entering avalanche terrain without the gear trio. Even on a "low-danger" day, the gear goes with you. If you're curious about the broader category of safety equipment on the water, our low-head dam safety guide is a useful parallel read on why gear redundancy matters in moving water.

Avalanche Myths Debunked

The Utah Avalanche Center popularized myth-busting as a teaching tool. Some of these circulate for decades because they sound plausible. All are wrong.

Myth	Reality
"Loud noises can trigger an avalanche."	False. Avalanches are triggered by adding weight (a skier) or stress (a cornice fall) to a weak layer. Yelling does nothing.
"You can outrun an avalanche."	False for skiers and snowboarders. Dry slab avalanches reach 60-80 mph within five seconds. Snowmobilers can sometimes power out the top.
"Digging yourself out is realistic."	Almost never. Debris sets like concrete. Even strong, equipped survivors cannot dig themselves out.
"The weight of the snow crushes you."	Misleading. Debris is 60-70% air. The killer is CO2 buildup, not chest compression.
"If you're buried, you should fight to dig upward."	Wastes oxygen. If you cannot break the surface with one arm, stay calm and conserve breath.
"A small slope is always safe."	False. Any slope between 30 and 50 degrees with a weak layer can avalanche, regardless of size.

The Aftermath: What to Do Once the Snow Stops

This section is missing from almost every other avalanche guide online, and it's where bad outcomes get locked in. Once your group is safe and the dust settles, here is what to do next.

Treat for Hypothermia and Trauma First

Anyone fully or partially buried, or who has been in the snow for any extended period, is at risk of hypothermia even on a mild day. Get them out of wet clothing, into insulating layers, and out of the wind. Treat any obvious injuries (broken bones from collisions with trees) without moving them more than necessary.

If the victim is not breathing, clear the airway and start CPR. Hypothermia can protect a cold body for a short window, so do not give up on resuscitation too early.

Watch for Secondary Avalanches

The same weak layer that produced the first slide can release again. Many avalanche professionals are killed in secondary slides while performing the original rescue. Before you commit to a long dig, scan the slope above and look for fresh cracks, collapsing snow, or recent releases. If the slope is still loaded and primed, the safest decision is sometimes to wait for organized rescue.

Call for Help: PLB, Satellite Messenger, or Phone

If you have a personal locator beacon (PLB) or a satellite messenger (Garmin inReach, ZOLEO, etc.), activate it the moment you confirm a serious burial or injury. Cell phones rarely work in the backcountry; do not rely on them.

When calling, give the dispatcher your GPS coordinates, the nature of the incident, the number of victims, and the conditions on the slope.

Helmet and Head Injury Check

Anyone who was tumbled in the slide, even briefly, should be checked for head injury. Concussions and neck injuries are common in violent slides. If the person was wearing a helmet, the helmet likely absorbed the impact. If not, treat any loss of consciousness or persistent confusion as a serious sign.

How to Not Get Caught in the First Place

The best avalanche rescue is the one you never have to do. These four habits separate survivors from statistics.

Check the Avalanche Forecast Every Time

Every avalanche region in North America publishes a daily forecast at avalanche.org or avalanche.ca. Read it the morning of your trip. Look at the danger rating, the avalanche problems, and the locations and elevations flagged as dangerous. If the forecast is considerable or higher, your terrain choices must shrink accordingly.

Take an AIARE Level 1 Course

The American Institute for Avalanche Research and Education (AIARE) Level 1 is the standard entry-level course for backcountry travelers. It is two days of classroom and field work covering terrain assessment, snowpack analysis, rescue, and decision-making. If you ski, ride, or climb in avalanche terrain without this course, you are guessing.

Carry the Non-Negotiable Gear Trio

Every person in your group carries their own beacon, probe, and shovel. No exceptions, even on "easy" days. If you fly by helicopter, double-check the gear before the next run. If you snowshoe mellow forest trails, you still need the trio if your route crosses avalanche paths.

Travel One at a Time Across Slopes

The single most important group safety rule: only one person at a time crosses a suspect slope. Everyone else watches from a safe spot, ready to perform a rescue. The rule looks slow; it is the rule that keeps your partner from being buried alongside you.

Frequently Asked Questions

Final Thoughts

If you only remember three things from this guide, make them these: escape off the slab at 45 degrees if you can, create an air pocket in front of your mouth as the flow stops, and treat your partners with a beacon, probe, and shovel as the only way to beat the 15-minute clock.

If you're a backcountry skier or snowboarder who spends most days in avalanche terrain, take an AIARE Level 1 course this season and rehearse companion rescue with your partners until the sequence is automatic. If you're a snowmobiler, angle your throttle uphill the moment a slope collapses and shed the machine if it is dragging you under. If you're a climber or snowshoer, treat every slope between 30 and 50 degrees as suspect and travel one at a time.

The best way to survive an avalanche is to not get caught in one. Read the avalanche forecast every morning in 2026, wear your beacon even on "easy" days, and never let a bluebird day override your terrain choices.
