This is next to the Mill Creek Canyon Road before the Alexander Basin Trailhead. This happened sometime during the last storm cycle as the groomer has taken away some of the debris pile but there is also one inch of new snow on top. Surrounding snow showed depth hoar/facets on the ground. The debris pile indicated this was a soft slab by the density of the snow and the way it folded on itself at the toe. This avalanche ran to the ground made of small loose rocks, dirt, and some small vegetation. There were also pinwheels on the slopes by the road, indicating a warming snowpack.
