Bottom Line: The snowpack stabilized with this week’s warm, dry weather. Look for signs of wet snow instability with temperatures in the 40s F through Saturday. Assess how new snow bonds to our existing snowpack as winter returns later this weekend.

  • "While skinning up to the top of Powder Park lift at Bridger, we had roughly 15' cracks propagate on an E/SE aspect. A snowpit showed roughly 8" of wind slab above a few inches of facets, on top of last week's rain crust." November 11, 2019.

  • A local near Fairy Lake gets a taste of fresh October snow and wind. "You know it's somewhat windy when the goats start closing their eyes and their beards get blown sideways." Photo: B. VandenBos

  • Strong westerly wind scoured snow off high ridgelines and slopes in the northern Bridger Range on Friday (10/11). Photo: B. VandenBos

  • Dry loose snow avalanches were observed on 10/10 as the recent snow settled. From e-mail "...saw some small, solar-initiated, dry loose snow slides in steep, rocky terrain (heads up ice climbers). With a firm surface beneath the new snow, these little guys were picking up steam quickly." Photo: B. VandenBos

  • Avalanche debris on the saddle near Hyalite Peak. This is indicative of the type of heavily wind loaded terrain near ridgelines where avalanches are most likely this time of year. Photo: B. VandenBos

  • We put up the Lionhead weather station on Tuesday, October 8th. There was 4-6" of snow above 8,000'. Photo: GNFAC

  • Broken off cornice on the saddle between Blackmore and Elephant on 10/5. "Snow was anywhere from inches deep with grass and rocks to hip deep. It was mostly knee deep though. Down in the flats below the bowl there was easily 8-10" fresh and another 2" on my way down..." Photo: @benjacobsenphoto

  • We hiked in to put up the Flanders weather station on 9/25 and found a spotty distribution of 4-6" of snow above 8,000'. Photo: GNFAC

  • Last weekend (9/23) there was about 14 inches of snow at 9,000'. Sun and warm temperatures created wet snow avalanches on slopes that face the sun. These small slides can be hazardous if they push you into the wrong terrain. Photo: Z. Drobnik
