Large, D4 avalanche. Probably triggered by cornice drop and/ or windloading during Feb 7-10 storm. Failure layer, small, < 2mm facets. Avalanche debris hit Hammil Lake and broke lake ice. Pits dug along flank of avalanche at 10,100 ft. 5-10 crowns ranging in elevation from 10,000 to 11,000 feet. In places above smooth rock surfaces, avalanche stepped down to old depth hoar and facet layers.
