Avalanche Summary
No new avalanches have been reported.
Snowpack Summary
The snowpack is currently quite stable in most places, however there is a weak layer of surface hoar (feathery crystals) and sun crust on steeper south facing slopes. This layer is down 20-60 cm. The surface hoar is most prominent at treeline. There have been no recent reports of reactivity on this layer. However, on large south facing features at treeline, the surface hoar may be sitting on top of the sun crust and should be treated with caution.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.
