Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Snowing, with moments up to 1" an hour!
2" accumulation from 11 am - 4 pm, on top of 4" overnight
Generally obscured skies, temps high 20s to 30 degrees at the road
Occasional light variable winds

Snow surface

Fist hard high quality new powder!! Ski penetration of 8-10", which was enough in places to lightly feel the New Years Crust while skiing down.


The Summit snowpack is very different from that observed at Turnagain or in the Girdwood Valley at similar elevations, with generally 10-14" of soft snow over the New Years Crust. This crust - like elsewhere in the region - has high spatial variability, ranging from difficult to punch through to almost unnoticeable with ski pole probing. The crust at the pit location and nearby locations consisted of multiple melt freeze/facet layers, down 30-45cm from the surface. This sat on 10-15cm of fist hard facets - 1-2mm in size - that failed inconsistently in CT tests, and didn't fail in an ECT. See pit and test results below.
