Avalanche Summary

No new avalanches have been reported in the past few days. Observations are limited this time of year, please consider filling out a MIN report.

Snowpack Summary

Expect early season conditions with a shallower than average snowpack, at treeline depths are between 30-80 cm. Below treeline snowpack depths taper off quickly.

Surface conditions are variable. A sun crust can be found on steep south and west facing slopes, and wind effect exists on exposed terrain at treeline and above.

A crust with facets or depth hoar exists at or near the ground.
