Avalanche Details

Evidence of a Natural slab avalanche (wet slab) on South aspect into Tenderfoot Creek. Rain/ wet Snow mix in this area over the past 24 hours. It slid on a short steep slope just above the sparse trees at the right hand side of the lower snowfield. This area has a slope of about 35 degrees. A good indicator that there is instability at lower elevation as well as upper elevations. See pictures this avalanche as well as avalanches from upper elevations on West Aspect of Butch Peak. Additional avalanche debris could be seen at Moose Mt North (Also west Aspect)
