Observer Comments

At approx. 1600 noticed what looked like recent avalanche debris at about 3600ft on the N. aspect and just below the top of the ridge running NE and about 1mi from VABM Hatch. Don't recall seeing it on my way up the mtn in the am. Observed skier tracks both above and below the debris. Appears to have released near the top of a short steep rollover just below the ridgetop. Maybe the beginnings of a cornice that didn't quite happen (pic).
