THE AVALANCHE TRIANGLE

The outside of the avalanche triangle presents us with three, critical considerations—Snowpack, Weather and Terrain. All three of these considerations must be in play to produce an avalanche. Additionally, these focus areas are objective and observable. When we find instabilities and weaknesses in the snowpack, we note them. When it’s snowing, we see it. We measure slope angles and recognize avalanche terrain via steep slopes, convexities, vegetative clues and likely trigger points. This is all very objective information.

So if we can see all these problems and objectively call them out, why are riders still getting into trouble in the backcountry?

THE CENTER OF THIS TRIANGLE IS US, THE HUMAN.

Humans are emotional, ego driven creatures. We see what we want to see. We often do what we want to do. But in terrain of consequence, that’s a dangerous approach to staying alive in avalanche terrain.

“The Ego is not your Amigo.”

Use the avalanche triangle to organize and reflect upon key considerations related to Snowpack, Weather, Terrain and Humans. The more information we have, the more informed actions, decisions and options we’ll have available to us.
