Observation

Description of Snow, Weather, and Avalanche Conditions:

In between runs at Silver Peak we observed a recent skier triggered avalanche. This is on the skier's right ridgeline of the East Bowl, down a ways from the summit ridgelines. It appeard to be a wind slab, but we were not able to get close from our location. 2 tracks entered and exited the slide, so we assume nobody was caught or injured. Approximate time was 11:30 am.

We also observed 4 other D1-2 avalanches that had the overnight snow on top of debris suggesting they were triggered yesterday. These were similar to some of the reported wind slabs from 3/25.
