Avalanche Summary

A few small (size 1) loose avalanches were reported on Tuesday, and some skier-triggered wind slabs were reported in alpine terrain on Monday (up to size 1.5).

Snowpack Summary

Variable wind has redistributed low-density snow at higher elevations.

A layer of surface hoar may exist 10 to 20 cm below the surface and a widespread, supportive crust exists 30 cm below the surface.

Snowpack depths decrease rapidly as you lose elevation below treeline.
