Remotely triggered by a skier from 75' away. This slide ran down and covered the summer trail with a reported 4' of debris, 100-150' wide. It occurred on a slope that was actively being wind-loaded.
This avalanche involved a very dense slab. This slope is very exposed to the effects of the wind and sun and the snowpack at the crown was not a well-stratified one and the details about weak layer involvement are a little murky. Details of the crown had been obscured by ongoing loading when SAC forecasters visited the site the following day. This slope is relatively narrow at the top, but the crown extended a long distance down the ridgeline on the looker's right side of the slope and the crown width is an estimated 1/4 mile.
