Comments
I saw fairly widespread, natural avalanche activity on all the steep terrain above about about 9,500' facing north through east. It presumably slid during the high precipitation intensity periods on Friday night or Saturday. The widest avalanche activity was in Dog Dish and the northeast aspect of Lake Peak, as well as a number of smaller rollovers throughout the basin. Most were about 1 1/2' deep and up to 500' wide. I experienced many big, collapses everywhere I traveled on the flats and shady slopes above about 9,500'.
