Problems

Loose Dry

Recent storm snow is settling yet the potential for sluffing to catch a skier off guard remains our main concern. Caution skiing over terrain traps like cliffs and gullies in steep terrain where the consequences of a small stuff are magnified.

Be cautious of sluffing in steep terrain.If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.
