Snowpack
The snowpack really only consists of two to three layers currently. The slopes with no snow before 11/17 only feature two layers from the two storms this week. On sunny slopes, a crust formed on top of the 11/17 layer, making it easy to distinguish between the two storms. In the shade, the two storm layers will soon blend into one. The areas where you'll find a 3-layer snowpack are where old snow persisted from October, which is currently a very shallow layer of well-developed facets capped by a melt-freeze crust (likely from warm temperatures and then rain at the onset of the 11/17 storm).
