Notes

A backcountry skier wrote, "...observed a fairly large, cornice -triggered avalanche on an east aspect at 9600’ that looked to be several hours old. The crown was 40-100 cm deep, and it looked like it failed about 20 cm into the facets that make up the lower half of the snowpack in this region."
