A snowmobiler triggered this slide around 10 am on Wednesday morning. The slide occurred on the south face of Crown Butte outside of Cooke City. Fortunately the rider who triggered the slide was not caught. The slope was heavily wind loaded and the slide failed on a layer of facets near the ground. It's still very possible to trigger large and dangerous avalanches around Cooke City. Photo: GNFAC
