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)
Obvious signs of instability
| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | No |
| Cracking (Shooting cracks)? | No |
Observer Comments
Recent avalanche activity on West Aspect of Butch Peak as well as Moose Mountain. Lower elevation avalanche on South Aspect Tenderfoot Ridge. Recent snowfall of 6" of snow near Summit Lake and 12-14" new snow on the North side of the pass (Manitoba/Fresno). Wind blown slopes were observed at upper elevations on East Aspects.
