Snowpack Summary
A light dusting of new snow now covers the melt-freeze crust that formed at all aspects and elevations. On north aspects this surface crust is thin with dry, sugary snow crystals (facets) below. Beneath the surface, the upper snowpack is well settled and overlies a thin layer of facets on the late-November rain crust. Recent snowpack tests from earlier this week have found hard, sudden compression test results on the facets just above the crust, which is now buried between approximately 60 cm at treeline elevations. Beneath this crust the lower snowpack is well settled and consists of several crusts that formed in the early season.
