  Steep cross or lee winded slopes with steep convex roles are likely slab trigger zones. In the alpine the snowpack depth is highly variable. At treeline travel is good and the snowpack supportive.

  Avoid steep cross winded terrain such as old moraines or shallow gullies. Additional loading can trigger large avalanches where the snow has been stiffened by the wind. No new avalanches seen from this layer in the Bald Hills today.
