Snow surface

Soft moist powder, 5-10" ski pen, in trees. Wind effect above treeline along with a large amount of challenging breakable wind crust in open areas above treeline.


General height of snow was 3' above the treeline and 1-2' below treeline.
Wind crust up to 5" and hard wind slab found above treeline. Under this we found a stable snowpack. The facet/crust combination that now sits around 2-2.5 feet deep that we were investigating did not show signs of failure or propagation at 2,700'. See pit profile.
