Northern San Juan

Steeper slopes with wind-drifted slabs resting above weak, collapsible snow layers are more problematic. Small, shallow avalanches may break deeper where older, weak layers are closer to the surface – slab margins, near exposed rocks and trees, and on steep rollovers. Avalanches on slopes with less than 3 feet of snow could take the entire season’s snowpack with it. Move to a different slope or lower angled terrain if you see cracking in the snow.
