Photo taken by Bill Brandt looking across to Chilly Peak Slabs where two tracks enter - and then exit - an avalanche. Looking to the right of the avalanche, you can also see the crowns of other avalanches in a steep gully that may have pulled out sympathetically from the skier-triggered avalanche or were remotely-triggered from the skiers on the ridge. Dimensions and weak layer are unknowm but the slope was likely wind-loaded.
