Decreasing Danger
Problem #2 Comments
The structure in the lower snowpack is still not terrific on high northerlies, though a very dense slab mid-pack has made triggering anything very difficult.
Comments
We dug in Powder Park III at 9000' on a North aspect (HS135cm) and had an ECTP22 on the facet interface down 110 cm. Failure was on a P to 1F transition. Facets were 2-3mm, rounding and moist.
