We climbed to the Upper Mummy's (west facing) and found relatively little snow at 9,000'. Gullies that usually fill in from wind-loading were not showing much depth. HS was less than 6 inches on the hike up (see pic). Across the valley looking at Elephant and Palace Butte, the bowls were snow covered, but barely (pic). Lower elevation, east facing slopes were mostly mostly dirt.

The avalanche danger is non-existent on most slopes. The exception would be high elevation gullies that happened to get wind drifts, but these are not widespread.

Wind was calm and skies were sunny, with an air temp in the teens F.

The mountains look good with a fresh coat of paint, but the snow cover remains thin. Photo: GNFAC

Went to do maintenance on the Sawtelle Snowfall weather station at 8800 ft just off the Sawtelle Mountain Road. Continuous snowcover starts around 8000 ft. At 8800 ft there is ~20" of snow with a mix of hard crusts and weak facets. These weak layers near the ground will be something to watch once snows again. Photo: GNFAC

Skier triggered windslab in the Great One off of Naya Nuki peak, skier was carried 15-20ft before arresting. Slide was triggered roughly halfway down the couloir where the right wall dips away exposing the snow to wind. Hard consolidated snow over facets, roughly 1-1.5 ft thick, ran about 50-100 ft before pouring over the cliff faces below. North- northeast aspect. Photo: J. Alford 11/8/2023

A hiker at Bridger Bowl noticed a small, loose snow avalanche near the Apron. Noting that it was a, "Good reminder as to how little snow is required to have an avalanche!" Photo: A Crawford

From obs (10/29): "Went for a skin up to Hyalite Peak yesterday to check out snow conditions. We found about 8-12 inches of new snow sitting on a base at Hyalite Lake. We saw no signs of instability in the area. Small cornices were observed on the Hyalite saddle, and a hit or miss 1 inch wind slab directly below the ridge." Photo: T. Saulnier

From IG: “Pine creek today, some small wind slabs and a full depth wet slide off black mountain”

From obs. "Was out alpine climbing today and observed the north face of Blackmore had slid already."
