The most dangerous areas are where you find wind-drifted snow on the leeward sides of ridgelines near and above treeline. Here, you can trigger a slab avalanche that gouges into older, weaker snow and can grow large enough to bury you. You can move to wind-sheltered slopes to reduce your chances of triggering a slab avalanche.
However, if you move to wind-sheltered terrain facing northwest through north to east you can easily trigger a small loose avalanche on very steep slopes. Even a small avalanche can knock you over and take you for a dangerous ride. You can decrease your chances of triggering a loose avalanche by avoiding travel on slopes steeper than about 35 degrees if your feet, skis, or machine sink deep into the snowpack.
