We saw this natural avalanche on a wind-loaded slope behind McAtee Basin. Photo: GNFAC

Skiers on 03/24/2024 saw the crown of this avalanche on an east-facing slope on Emigrant Peak. This likely happened sometime during last week's warm temperatures. Photo: O. Cole & M. Mundt

Skiers on 03/23/2024 saw this wet slide on the back bowl of Emigrant Peak. This likely happened sometime during last week's warm temperatures. Photo: M. Hebner

From obs. 3/23/24: "...Natural wet slab avalanche in the Playground, just North of Texas Meadows. It seemed to have been triggered from a wet loose avalanche that released from the cliffband above...." Photo: D. Sandberg

From obs 3/23/24: "...Also observed wet loose activity in S facing run off Texas (first run to the W of the summit)-photo attached. ..." Photo: D. Sandberg

From obs.: "Walked out the north gate of Bridger to the playground. Just north of Texas meadows observed a slide that ran sometime earlier in the week on a E aspect. Seems to have been triggered naturally by a loose wet coming out of the steep rocky terrain above. Ran about 200 feet was about 50-60 feet wide and crown was roughly 2-3 feet deep. Snow around the slide and on similar aspects was wet in the top 40 cms or so." Photo: C. Bayles

The avalanche occurred on the northernmost ridgeline in the Mt. Blackmore system near the waypoint at the top of the image. GNFAC/ Gaia

Two skiers were ascending a northeast-facing avalanche path on the northernmost ridgeline of Mount Blackmore around 1 PM when they triggered a large, dry slab avalanche that failed 3 feet deep, 150 feet wide, and ran 500 feet vertical. Debris piled up 4-8 feet deep and broke a number of mature trees. Photo: GNFAC

My partner and I were approaching Responsible FamilyMan via Avalanche Gulch early yesterday morning (3/18), and once we broke through the trees into the runout zone, we stumbled across a pretty large wet avalanche debris field. The debris terminated within ~50 yards of the max runout zone. Photo: R. Parsons

We dug below the first cliff band and found 7' of snow, the bottom 2' consisting of weak facets. A Deep Tap Test showed a clean shear at this interface. An avalanche could be triggered by 3 ways: more load from snowfall or wet avalanche debris, melt-water percolating through the snowpack to the facets, or human triggering from a thin spot.
