Avalanche Details

The avalanche looks like it happened during one of the many rain/heavy snow events last week. The crown is 3-6 feet deep and deepest when it contacts a big rock, 100-150 feet wide and created a large debris pile 800-1000 feet below. It is several days old but impressive nonetheless.
