Avalanche Summary

You can easily trigger an avalanche on northerly and east-facing slopes where wind-drifted snow rests on old, weak snow. You trigger avalanches from below or from a distance so be aware of steep slopes overhead. Watch for and avoid wind-drifted snow on steep slopes below ridgelines, in gullies, and on steep rollovers. Safer terrain exists on slopes less than about 30 degrees steep with no steep slopes above you. Southerly-facing terrain lacks the old weak layer below, so look here for safer options.
