Large natural avalanches have been observed in the mountains around Cooke City. Nearly four feet of snow in the past 4 days has created very dangerous avalanche conditions and a widespread natural avalanche cycle. Photo: F. Madsen

This slide occurred just off the road leading into Cooke City. Small avalanches are key indicators that much larger avalanches are possible. Photo: Kt Miller

This natural slide was observed in Tepee Basin in the southern Madison Range. Heavy snow and a weak snowpack structure are producing very dangerous avalanche conditions. Photo: B. Radecky
