Snowpack Summary

A variable snow surface generally includes a supportive crust with surface hoar or surface facets, all breaking down to corn snow with daytime warming and sun-exposure. In general, the snowpack is strong, but may weaken during peak warming periods. Cornices may fail with warm temperatures. Wind slabs may be found in the alpine, or lower in glaciated drainages from katabatic winds.

Problems

Wind Slabs

Wind slabs may be lurking on lee and cross-loaded terrain at and above treeline, and in glacial drainages from downslope winds. Cornices are fragile and may collapse.

Be cautious as you transition into wind affected terrain.>
