Public Submission: Low visibility prevented observers from seeing the avalanche's starting zone. As such the primary aspect, elevation, and size are rough estimations. This natural avalanche likely occurred mid-day yesterday (11/23/2024) as several inches of rain fell onto the fresh load of snow from this week's atmospheric river. The wet slab avalanche ran down to about 7,500 feet where it left debris piles up to 12 feet high in an 800 foot long deposition zone.
