Avalanche Details

The top of our run had a very small fresh windslab that stayed stuck to the slope as we ski tested it. Lower on our run, below the rocks, we skied through a fresh natural avalanche on a wider slope. We chose this run because were able to follow the track of this fresh avalanche to gain access to the lower angle good powder below. The avalanche looked to be new snow from the past couple days that avalanched off and travelled far down the hill. A nearby skier ski triggered a similar avalanche in steep rocks, but was not caught.
