Notes

A snowmobiler jumped and did a cannonball onto a very small slope, triggering an equally small avalanche. This was a clear sign that larger avalanches are likely on bigger slopes.

Notes

Rode along Lionhead Ridge from Denny Creek to Watkins Creek and around into the head of Targhee Creek on 1/26/24. Saw dozens of avalanches that broke within the last week. Most of the slides looked to have broken early this week. 1/23/24 date is approximate. Slides broke on all aspects, both above treeline and well below treeline, and on both wind-loaded and nonwind-loaded slopes. All these slides looked to have broken on one of the December surface hoar layers at the top of the early season facets.

A slide in Watkins Creek broke across three avalanche paths/gully features and was one of the larger slides we've seen this season, looking to have piled up debris 10+ ft deep. Looks to have broken in the last 24 hours. 1/26/24 Photo: GNFAC
