Avalanche Summary

On Tuesday, a size 1 storm slab avalanche was triggered by skiers on Feather Peak, just west of the forecast region. Details can be found in this report.

Early season observations are limited. Please post any pictures or information to the MIN.

Snowpack Summary

The snowpack remains shallow at lower elevations with open creeks, exposed rocks, and other early-season hazards.

However, reports suggest that much more snow has accumulated in alpine terrain during the recent warm stormy weather. A crust is buried anywhere from 0 - 50 cm depending on your location's wind exposure and elevation. A thick crust has been reported near the base of the snowpack.
