Snowpack
Dug on a NW aspect at around 2,500' at the edge of the treeline. Got to ground at 160cm.
New/settling snow in the top of the pack, then a smaller layer of slightly more cohesive and compact grains that feel wind affected. Down 50cm was the facet layer (about 40cm thick with an ice/melt free crust down 82cm. Between this icy layer and the top of the facets was where all the reactivity was observed (no results from the ECT test as mentioned in the forecast).
