Snowpack Summary

A sun crust exists on solar aspects. Recent southeasterly winds formed wind slabs on a variety of aspects at treeline and above. The above mentioned winds have formed large cornices.

These slabs are sitting on a crust that may have small facets associated with it in isolated locations.

The mid and lower snowpack is well-settled and strong.
