Natural Avalanche, Specimen Creek

From obs: "Observed 2 natural avalanches, both on the basal persistent layer I would guess. one maybe a week old, partially filled in (SS-N-D1R2-O), and one that ran in the last 24 hrs (SS-N-D1.5R2-O) on a SE aspect, 35 deg at 8200 ft. I thought it was interesting given the lack of new snow and seeming lack of strong winds in this area." Photo: S. Hennessey
