Snowpack Summary

A trace amount of new snow fell overnight but not enough to really bury the surface hoar that has been growing on all aspects up to 2400m. The Dec 13th interface is down 30-40cm and continues to produce moderate sheers on a layer of facets over this crust. This crust, the Dec 13, is only being found up to 2250m-ish. Below this the mid pack is generally well settled with the 1106cr down 1m. Most alpine terrain is wind hammerred and even some areas down into treeline saw some wind affect on Friday.
