Main Porter Fork
I was interested in looking at snowpack in Millcreek after seeing Peter Earle's observation of a likely remotely-triggered slide in Porter Fork on Sunday. Main Porter is steep-sided, and the steep gully where this slide is located is shaded (photo). But I was also finding weak snow down near the ground on northwest and west aspects from 8200' and above. The slab above the facets continues to strengthen, and is now 4F to 1F in hardness.
Settlement cones around trees and shrubs are an indication of the low-density snow from this past week settling and the slab gaining strength.
Video discussion of what we found on northwest aspect at 9400' in Millcreek.
