Avalanche Details

Today we witnessed two skier triggered soft slab avalanches. The second also caused a sympathetic avalanche. The first avalanche had a 75cm deep debris pile. The runout angle was 33 degrees. The second avalanche was bigger, but we did not go up to investigate.
The weak layer was new snow over a sun crust.

Events of the day

Our group was touring up the road and witnessed the first group skiing down. After we saw the avalanche we went to check out the slide. About 30 minutes later two more skiers came down and set off the second avalanche.
All skiers were able to ski out of the path.
