Bottom Line: It is barely fall, but with layers of snow piling up in the mountains bigger avalanches are possible. Avalanches this time of year are not uncommon, and have injured and killed people in past seasons (accident reports). If you plan to travel in the backcountry, whether skiing, climbing or hunting, prepare for avalanches like you would all winter. Avoid steep slopes with fresh drifts of snow, especially where even a small slide could push you into rocks or trees, or pile up deep in a confined gully.
Primary Problem: Wind-Drifted Snow

Aspect: N
Coordinates: 45.1582, -111.4770
Caught: 0 ; Buried: 0

From e-mail on Saturday 10/5, climbers on the Sphinx found these conditions: "We found a lot of snow on the Sphinx today following heavy precip since Sam’s report two days ago [see photo]. 3-5 cm in the parking lot, 20 cm at the Sphinx-Helmet col. Moderate SW winds had created drifts almost a meter deep in places on the traverse to the ice routes on the north face. I backed off after a whumph on a particularly exposed section of the traverse. We tried different ledge systems above and below the normal approach route but found similar snow conditions throughout."

Photo: From 10/3 prior to 8-10" new snow, "No snow hazard of much concern on the approach. However, a quick hasty pit in an isolated wind pocket revealed a CT1 on this layer.  ice axe is to the ground."

From e-mail: "The only places one could ski were wind pockets blown into the limestone fin features that in places were well over a foot. These spots were also where the snow was weirdest/posed any sort of avalanche hazard as you pretty much had to find a wind slab in order to ski anything! One group reported triggering a slab in one of these spots, but vis was too poor to see."

  • Strong winds scoured new snow off some slopes and loaded it into thick drifts on other slopes. Slopes with thick drifts of snow provide the only place with enough coverage to ski, but are also the most likely place to trigger an avalanche right now. Photo: B. VandenBos

  • 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

  • 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

  • The mountains got their first coat of snow at the end of September, though it isn't quite enough to protect you from hitting rocks. Where the snow is drifted provides the best coverage, but is also the most likely place to trigger a small slide. A small slide would be painful if it pushes you into the many exposed rocks.

  • 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
