Drove through Summit Lake between 12pm and 12:45pm. We witnessed a natural avalanche in motion on the West face of Tri-Tip, debris came to a stop ~200 vertical feet above the lake elevation. There was evidence of wide spread avalanche activity on Moose Mountain West, North aspects and South face, Tenderfoot SW face. Visibility was descent, and couldn’t see any new activity on East facing aspects of Fresno, Colorado, and Summit.
