Avalanche Triangle – Sorting Information

The avalanche triangle is one way to sort information in the world of snow and avalanches. We can sort information using TERRAIN, SNOWPACK, WEATHER, and the HUMAN FACTOR.

When thinking of terrain, we ask “Is the Terrain Steep Enough to Avalanche?” The majority of slab avalanches occur in terrain that is 30° – 45°.

When thinking of snowpack, we ask “Is There a Recipe for an Avalanche? Is there a SLAB, WEAK LAYER, BED SURFACE and are we in TERRAIN steep enough to avalanche?”

When thinking of weather, we ask “Is the Weather Contributing to the Instability?”

And when thinking of the human factor, we ask “Is my Group Working as a Team?”

What to wear for a backcountry tour

Watch the video regarding how to dress for backcountry travel.  Layering is important when traveling in the backcountry, as you often warm up as you’re climbing and cool down as you are descending. Layers allow for simple, efficient temperature regulation.
