Snowpack Summary
10 cm of snow fell on Friday resulting in a total of 20-30 cm of recent soft snow on the surface. In places it is heavily wind affected and sits above a variety of old snow surfaces including wind-scoured snow and faceted snow. At treeline and below, the recent snow sits on a widespread crust and pockets of surface hoar.
The snowpack is shallow and faceted with multiple crusts. Pockets of deeper snow may be found near ridges, gully features, and established avalanche paths. Average snowpack depths at treeline are between 60 and 100 cm.
