A group hiked into an ice climb below Pilot Peak on the Montana/ Wyoming border and remotely triggered an avalanche that failed 150 yards above them. They were on a lower-angle slope below and no one was caught or carried.

A rider from MN triggered an avalanche immediately north of Round Lake. He was caught, pulled his airbag and was buried with his head out, under his sled. He attributes this to his airbag. His partners dug him out and he was uninjured. Photo: Anon

We could see this avalanche on the nose of Sheep Mountain from Henderson Bench. This is the slope that killed a snowmobiler in 2015. Photo: GNFAC

#1 was an avalanche from 1/25 on Henderson Mountain. #2 and #3 looked fresh, possibly cornice triggered. It was not windy, so windloading was not the trigger. Photo: GNFAC

On Henderson Bench we saw 2 new avalanches that looked fresh, possibly cornice triggered. It was not windy, so windloading was not the trigger. Regardless, it was disconcerting. Photo: GNFAC

A 70 cm wind slab broke on the facets in our stability test (ECTP 21) and also in the avalanche. Photo: GNFAC

We rode to the cabins in Fisher Creek and skied up Wades World. A slide from last week was visible and we dug a few hundred feet above it. Photo: GNFAC
