Blewett Pass area

Dec. 29, 2015, 1 p.m. PST

Weather: Mountain fog all day, early snowfall then dry, around 17F all day.

Snowpack: From skin track observations and skiing, snowpack is very stable but not deep. At our profile location on a N aspect at 5600', snow is loose and dry at the surface and progressively more cohesive as you dig down to the thick rain crust layer at 1m. We found some sensitivity (CT15) about 25cm down, poor quality shear and no evident crust or facets there; no reaction on the rain crust 100 cm down. Sugar snow between the rain crust layer and the rocks ~5cm below. Elsewhere we saw surface hoar at about 5500', found firm wind crusts just ~10 cm down in exposed areas, and hit a few rocks. Total HS 120cm at 5600'.
