Avalanche Summary

No new avalanches have been reported since last weekend.

Early season observations are very limited. Please consider sharing your observations with forecasters and the backcountry community through the Mountain Information Network.

Snowpack Summary

The alpine and exposed areas at treeline generally have hard wind affected surfaces. Winds are forecast to change direction Saturday afternoon. Small pockets of triggerable wind slab may form in isolated terrain.

In lower elevation sheltered trees, surface hoar and facets are developing. These sit on top of 10-15 centimeters of soft snow overlying older firmer snow.

The snowpack is generally strong, with some crusts near the base.

Snow depths vary significantly across the region, with about 50 cm at treeline and up to 100 cm in alpine areas.
