Skiers on 02/21/2024 saw a few old crowns on a north-facing slope at 9000'. These probably happened sometime near the end of last week. Photo: W. Hubbard

From obs: "Photo of an avalanche observed yesterday (2/21) on the SW face of Sawtooth Mountain at about 10,600’. Looks to be a few days old, but hard to tell since all skier traffic from the weekend has been erased with Tuesday’s wind/precip. If you look closely, you can see the crown extends across the entire face." Photo: A. Joy

Skiers in the Pioneer Mountains remotely triggered this avalanche on 02/19/2024. From obs on 02/20/2024: "We descended on lower angle terrain following uptrack. On second lap observed the crown and debris while climbing uptrack and suspected we remote triggered; it was not there on first lap" Photo: A. Dunn

Riders on 02/18/2024 saw an avalanche that was triggered a few days prior on 02/16/2024. 

Riders saw recently triggered slides that were likely triggered by snowmobilers on 02/17/2024.

The skillet slid sometime recently. Based on the snow on top I'm guessing Thursday-Friday last week (Feb 15-16th), but it could have happened up to a week earlier. Broke ~2 ft deep, 150 ft wide, and it was hard to tell how far it ran, but I'm estimating 200 vertical feet. Photo: GNFAC

Close to the ridge and the starting zones of nearby avalanche paths, we triggered a large collapse that sent shooting cracks out a couple hundred feet. If the slope had been any steeper, we would have triggered an avalanche. Photo: GNFAC
