"I skied near Quake Lake today, and observed several signs that the snowpack has not adjusted to this last storm yet. While ascending, several drifts collapsed under my weight, and I observed a very recent natural slide on a wind-loaded, east facing slope at about 9200'. I saw another, larger natural slide on a wind-loaded N/NW slope at 9600' that looked to have run on the new/old interface sometime late yesterday. I dug a pit on a south aspect at 9900', and found a thin layer of graupel on top of a crust 35cm down. This failed at ECTP3, which was a little hair-raising. The rest of the pack on that aspect seemed to be fairly well consolidated..."
