Avalanche Summary
Recent avalanche activity is primarily limited to natural and explosive-triggered cornice falls and small loose wet sluffs from steep sunny terrain. There was a report of a size 1.5 accidentally triggered cornice on Thursday. Some cornice falls have been large (size 3), but have recently only entrained loose snow.
Snowpack Summary
The snow surface consists of a sun crust or moist snow on sun-exposed slopes (depending on the time of day), dry settled powder on shady slopes (cool temperatures have maintained good snow quality), and pockets of fresh wind slab in lee and cross-loaded terrain features near ridge crests. In general, the snowpack is strong and well-settled throughout with no notable persistent weaknesses. Cornices are reported to be large and fragile.
