Comments
Remotely triggered slab while ascending ridgeline from Twin Lakes Pass to Patsey Summit. While skinning up my partner noticed a shooting crack followed by a very loud collapse and subsequent slab release on the lee side of the ridge. Weak layer was the obvious faceted snow from October. The slab did not require much energy to release and was large enough to easily carry and burry anyone in the path. Location and slide characteristics consistent with forecasted conditions.

The shooting crack is visible in the upper right corner of the third photo. Apologies for photo quality...
