Avalanche Summary

You can trigger a large and dangerous avalanche on most slopes steeper than 30 degrees. Avalanches triggered from lower-angled terrain below steeper slopes or large avalanche paths could propagate uphill, creating a broader, more destructive slide. Wind-loaded, easterly-facing slopes have the deepest snowpack, and the largest avalanches observed on these aspects.

Stick to low-angled slopes. Smaller avalanches can become bigger problems if you get swept over a cliff, pushed through dense trees, or into a terrain trap. Know what terrain is around you and give steep slopes a wide buffer.
