A sun crust has formed on sun-exposed slopes at all elevations. In the alpine and exposed treeline, strong winds throughout the week have created a variety of wind-affected surfaces. Expect to find old and new wind slabs on a variety of aspects, with the most recent and reactive slabs formed in terrain features lee to the northwest.

Humans are unlikely to trigger it, with perhaps the exception in thin, shallow snowpack areas.
