Comments
Impressive natural slide in the Y today, first noted driving down canyon at about noon when skies were clear and light was good. Looked quite fresh at that point, I imagine it ran around dawn when winds seemed to spike from the SSE in LCC; particularly strong winds and drifting snow were observed driving up lower LCC around 615 AM. The slide appears to have run from near the very top of of the main branch of the chute, although debris in most other neighboring chutes suggests the tributary branches also avalanched. The debris looks like the slide may have started as a cold snow slide and gouged into rain-on-snow layering down low in the chute. Attached is an iphone pic from ~645 PM that does not do it justice; peel your eyes to see the debris stopping about 50' from the willows.
