Snowpack Summary

A sun crust is developing on solar aspects. In lee areas, multiple layers of windslab sit over the Feb 1st melt freeze crust which exists up to approx 2100m. Reactivity of this windslab is extremely variable. Expect windslabs to become more sensitive as temperature rises. The midpack is strong, though weaker basal facets can be found in thin areas.

Avalanche Summary

One size 2 natural windslab avalanche occurred on a E aspect at cameron lake between Monday afternoon and Thursday AM.

Continued cornice growth in the alpine.
