I skied above Hebgen Lake today, and found excellent surface conditions with poor stability. A pit on an east-facing slope at 8650’ had a clear line visible where the buried surface hoar is, and an extended column test yielded ECTN2 10 cm down on the interface between older snow and the new snow from the past couple days, and ECTP7 on the buried surface hoar. This layer is very well preserved. We did not experience any collapsing or cracking and saw no natural slides, but another group triggered two small slides on a he surface hoar while traversing a ridgeline at the top.
