Avalanche Summary
No new avalanche observations since Thursday when a small (size 1) wind slab was triggered by a sledder in the alpine.
Snowpack Summary
Small amounts of new snow falls over faceted and wind-affected surfaces. At upper elevations, west winds are redistributing the new snow into fresh wind slabs in leeward terrain features. Older, hard wind slabs sit over weak faceted crystals and a crust, 20 to 30 cm below the surface.
The mid and lower snowpack is generally well-bonded and strong.
