I just got done digging a pit near the top of the slope. My results were ECT 27 BRK and CT 11 RP above the January facets. The January facets were down 30 cm in an HS 130 snow pack. I had previously ski cut and skied an adjacent line to the slide. I felt the slope was safe to ski so I skied it. I was unaware the slide occurred until I was at the bottom. 3/4 the way down the slope there is a flat spot with very thin snow over rocks. I wonder if when getting off the deep part of the slab and crossing the thinnest part of the slab I triggered the slide and it pulled up the slope.
