Signs of Unstable Snow

Observations

At lower elevations and in sheltered terrain we found areas with 2-4 inches of loose, faceted snow over a thick ski supportable crust. Near the ridge line, we found that the wind had stripped the snow back down to the crust, particularly on NW aspects. SE slopes held more snow, but the surface was stiff and wind affected.

Variable surface conditions made travel difficult, and we avoided firm icy slopes.

Crowns and debris from the 12/21 rain event are still visible, and were an added travel hazard.

Snow began around 12:00 and precipitation intensity and wind increased significantly.
