Snowpack Summary
The snowpack is currently quite stable in most places, however a buried weak layer still exists down 20-60 cm. This layer consists of a sun crust on steep south facing slopes, and/or surface hoar (feathery crystals). The surface hoar is most prominent at treeline. The most likely place to trigger this layer is where the surface hoar is sitting on the crust. This combination is most likely found on steep south facing terrain at treeline.At the base of the snowpack is a crust that formed in late October. The probability of triggering this layer is low, but the most likely areas would be large, steep, rocky alpine features with a shallow snowpack. It would likely take a large trigger such as a cornice fall to produce an avalanche on this layer.Snowpack depths decrease dramatically with elevation.
