General Comments

Large overhanging cornices on the ridge just above the pine trees. As I was walking along up the ridge I was about 5 feet from the edge giving a few stomps and a chunk about 15-20 long broke at my ski tips. as we progressed farther up the ridge I continued to stomp and had the whole thing break off and shoot cracks up the ridge for 80+ feet almost to the top. nothing ran far just new snow sluffing, it stopped just before the trees.
