Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

For the most part the snow surface is some sort of hard crust or wind-sculpted snow, which probably has surface hoar growing on it and facets forming beneath it. The mid and lower snowpack are generally quite strong. If snowfall and wind materialize for friday night, a new wind/storm slab will exist in the alpine and perhaps down to treeline.
