Comments
Came across this human triggered slide on my tour today and noticed it hadn't been reported yet as of writing this. It was likely triggered yesterday on 12/11/2021. The slope angle at the crown was 37 degrees, it broke roughly 70' across the slope, ran roughly 150' down the slope and had an average depth of 12" (18" at its deepest) . The slide broke at the interface of the new snow and a thin layer of facets (1.5 - 2 mm) sitting above a crust. SS-AR-R3-D1-I
