A portion of the debris pile from a rider triggered an avalanche on 02/07/2024. This avalanche broke 3/4 of a mile wide and had multiple large piles of debris with this being one of the largest.

This avalanche was triggered by riders a few days ago. This was a small slope and broke 100' wide and 2-3' deep. Photo: GNFAC 

Natural avalanche on East Side of Henderson Mtn. seen late on 2/7/24. South of the two that Doug saw last week, along the ridge. Could have happened yesterday or last night. I didn’t see it yesterday when riding up and down Fisher creek, but visibility was mediocre. The debris and bed had at least some new snow on it. Photo: GNFAC

From obs: "Observed an avalanche above Highway 212 ("the plug") just north of the Wyoming/Montana border. that appeared to be triggered by a snowmobile. It looked fresh, likely from the afternoon of 2/6/2024. Northeast facing slope, 8200'. Technically out of the advisory area." Photo: N. Gaddy

We had one collapse, 10-12' wide near treeline where there was a little more wind-loading/effect. Photo: GNFAC

We dug a snowpit at 9,761' on a west facing slope south of Cooke City. ECTP21, 40 cm below the surface (16" down). There was 6-8" of new snow from the weekend above 4" of soft old snow, on top of 4" of a pencil- hard slab, then the soft sugary facets to the ground. ECT broke below the hard slab at the top of the facets. Photo: GNFAC

This crack opened up above our snowpit as we made our exit away from the steeper terrain of the "Skillet" run toward low-angle trees. Photo: GNFAC

We triggered booming collapses and watched cracks shoot out across terrain features and snow shake off nearby trees for the entirety of our tour from the meadow near the car to the top of the Skillet. Photo: GNFAC

From obs 2/4/24: "Multiple natural avalanches and at least one suspected human triggered dry loose in Beehive Basin. Most naturals appeared to have run either last night or yesterday (2/3/24), with a couple potentially older slides. Suspect one skier trigged dry loose in W facing trees..." Photo: M. Zia

A recent natural avalanche on seen on the NW aspect of Woody Ridge at 10,000'. Appeared to of happened today, 02/04/2024. Photo: N. Gaddy

From obs: "We heard numerous large-scale collapses and witnessed the development of propagating tensile fractures on a 20°-25° slope along the skin track.... We skied this location 4 times this week. Each time, we experienced collapsing and fracturing within the snowpack. and stuck to skiing conservative, low-angle lines." Photo: T. Kalakay
