Avalanche Summary

Warm temperatures and sun-exposure has resulted in small wet loose avalanches in steep south aspects.

Snowpack Summary

New surface hoar is growing, surface snow is faceting, and wet surface snow on south facing slopes is freezing into a crust overnight. In wind-exposed areas, expect to find a variable mix of hard wind slab, scoured areas, and sastrugi. The prominent feature in the upper snowpack is a thick rain crust from last weekend, which extends well into treeline elevations. The mid and lower snowpack is generally well settled and strong. Basal depth hoar probably lurks in thin snowpack areas.
