Snowpack Summary
A light dusting of new snow now covers the variable old surface consisting of; wind-scoured northwesterly slopes, areas of hard and soft wind slab on alpine lee slopes and exposed treeline areas, as well as a thin sun crust on steep solar aspects. Approximately 2-5 cm of new snow overlies 15-30 cm of old storm snow on top of the most recent December 18th melt-freeze crust, which has been unreactive in recent snowpack tests. Below this crusts lies 20 cm of well settled snow above the December 16th crust. Below this crust, a third crust, the 20 cm thick late-November crust, is now buried 40-50 cm. The lower snowpack well settled and moist to ground. Snowpack depths are about 135 cm at 1100 m elevation, with many early season hazards present at lower elevations.
