Cooke City, 2022-01-22

From email on 1/22/22: "This morning (20220122) I was ascending a steep North facing couloir up the N summit of Republic Mountain and on ascent (boot packing) about 1/2 way up the line I triggered a small soft slab from that propagated around the rock I was tucked behind, 40M above me and and 20M across. Luckily, my ascent line was sheltered from any above exposure and I was not caught or carried in anyway. The crown ranged from 8cm where I triggered it to an estimated 25cm at its deepest. The avalanche ran an estimated 200M. I believe the windslab ran on 1-3mm NSF's (evident on the bed surface) formed in the high pressure before the recent light precip."

On January 18, 2022 a weak layer of surface hoar was buried by 1-2" of new snow near Cooke City. As more snow builds a slab over this weak layer it will cause avalanches. Photo: GNFAC

A group in the Wolverine Cirque noted several small wet loose avalanches that occurred during recent warm weather. 

Lionhead Range, 2022-01-17

Riders in the Lionhead area noted that a layer of feathery surface hoar is continuing to grow. If this gets buried by the next snowstorm it will become a new weak layer. Photo: G Ewsuk

A group at Ernie Miller Ridge had an unstable test score in their second snowpit of the day (1/16/22). Lingering instabilities are isolated but it is an excellent idea to dig down and test the snowpack before getting into avalanche terrain. Photo: T Dumbrovsky

Bridger Range, 2022-01-16

In the northern Bridger Range we dug a pit at 8700 feet on a north facing slope before skiing the chute into the basin. Our stability tests did not break and all evidence pointed to a LOW danger. Photo: GNFAC

Lionhead Range, 2022-01-16

Riders reported on 1/15/22: "Some surface hoar is forming on nearly every aspect at all elevations. over 1 cm thick in some areas." Photo: B. Rasmussen
