Unstable test results South of cooke city

I was touring on the west side of Wyoming creek today. Got some large whoomfs and collapses on the Ridgeline and a poor test score of ectp11 q1 sp 22cm deep on on buried surface hoar on top of facets on an E/SE facing slope at 9242' hs-163cm, slope angle 26°  The same layer was easily identifiable in hand shears throughout the day.
