Bottom Line: In the last 36 hours the mountains picked up 2-4” of snow, except Cooke City, which got nothing. Wind has been gusting out of the east and blew this new snow into drifts at all elevations, our primary avalanche concern. These whales of snow, typically found in gullies, could be triggered by a skier, ice climber or hunter. Cracks shooting out in front of your feet or skis are a warning to not go further.
Primary Problem: Wind-Drifted Snow

  • 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.

  • 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”

The Last Word

We travel with a lot of electronics that could interfere with our avalanche transceiver, both as a victim and as a rescuer. Check out our article on Electronic Warfare to learn what to do.
