General Comments

The slope slid with just a small cornice kick and the whole chute cracked out and slid nearly full track. This looked to just be from wind loaded snow but further inspection down the chute showed some gouging in the bed surface below the new dirt layer.

Other instabilities noted are on North faceing slope below the dirt layer are small NSF that fail easliy in shear tests.
