How to Survive an Avalanche? | Backcountry Survival Basics

Surviving an avalanche starts before the snow moves: avoid steep slopes, carry a beacon, shovel, and probe, and know how to use them.

For the full breakdown, see our best Avalanche Rescue Equipment guide.

The honest truth about how to survive an avalanche is that most of it happens before the slide starts. Backcountry deaths are rarely the result of bad luck—they come from being in the wrong place, carrying rescue gear nobody has practiced with, or freezing when the slope releases. The sequence below follows official guidance: read the terrain, carry the right tools, and act deliberately if the snow cuts loose.

Read The Danger Before You Go

Avalanches release on slopes steeper than about 30 degrees, and Ready.gov is direct about the first rule of survival: avoid slopes steeper than 30 degrees and the terrain below them. That includes runout zones at the bottom of a slope, where debris can pile up even if you never triggered the slide yourself.

Before committing to a line, look for warning signs that the snowpack is unstable. Recent avalanches in the area are the most obvious clue. Shooting cracks that race out from under your skis or snowmobile mean the snow is under stress. A deep, hollow “whumpf” sound as the snow settles under you means a weak layer has just collapsed—a slide may be next. Any one of these is a reason to change the plan.

Surviving An Avalanche Starts With The Gear You Carry

The National Weather Service lists three essentials for anyone entering avalanche terrain: a transceiver (beacon), a shovel, and a probe. Ready.gov adds an avalanche airbag, a helmet, and a collapsible probe to that list. None of this gear prevents an avalanche—it changes what happens after one. A buried victim needs to be located, pinpointed, and dug out fast, and each tool does one of those jobs.

Gear only works if you have practiced with it. Ready.gov’s avalanche preparedness guide stresses knowing how to use rescue equipment, and official guidance also recommends first-aid training for suffocation, hypothermia, traumatic injury, and shock. Bury a beacon and practice the search pattern; time how long a full probe and dig takes. If you’re building a kit from scratch, our tested picks for avalanche rescue equipment break down what’s worth paying for.

If The Snow Releases, What Should You Do?

If you are caught in the slide, every second is a chance to change the outcome. The goal is to stay near the surface, protect your airway, and make it as easy as possible for companions to find you.

Move sideways toward the edge of the avalanche if you can. Grab a tree or rock within reach. Ditch skis, poles, and a heavy pack—they drag you under and pin you when the snow stops. Swim hard with a breaststroke motion to stay on top. When the slide starts to slow, punch one hand straight toward the surface; that hand becomes both a marker for rescuers and an air pocket shielding your face. Once the snow stops moving, stay calm and conserve air. If you cannot move, wait. Trained companions are already searching.

Companion rescue is the buried victim’s best hope. If you witness a burial, call 911, then begin searching immediately if conditions are safe and you have your gear. Mark the last-seen point—that is where the search starts. Switch your transceiver to search, follow the signal, probe to confirm the victim’s depth, and dig from downhill so the snow moves away from their face. This is time-critical; trained partners searching on the spot almost always beat waiting for outside help.
