Photo is from the ridgeline. This avalanche was triggered midday Wednesday (2/26) north of Bridger Bowl ski above Wolverine Bowl. The slide is east facing and broke 3-4 feet deep from a natural cornice fall. It broke 4-5 feet wide mid-slope and broke on the facets near the bottom of the snowpack. No one was caught. Photo: BBSP

Small natural wet loose and wind slab in S. Gallatins
From an obs on 2/23/20: "...today toured up above 9000 ft on Meldrum and some surrounding hills.... No cracking, collapsing, or naturals observed aside from some small wet loose that occurred yesterday in steep S rocky terrain at 8500 ft.... HS 150+ with depth hoar 130 down. The new snow will be falling on a variety of snow surfaces from crusts (E-S-W) to wind board (ridgelines) to NSFs (N). Temperatures warmed to above freezing today to at least 9000 ft. Winds increased to moderate out of the west by 1400 with some wind transport occurring at ridgelines."
From another group on Electric Peak on 2/23/20: "One recent natural avalanche near the ridgeline roughly 30 cm deep probably due to wind loading (D1) and a handful of natural loose wet (D1) avalanches on southerly aspects. Dug a quick pit on the face (10700’ NE 30 degree slope HS 190cm) and got an ECTP23 @ 35 below the surface on a hardness change below a 1F fresh windslab... Also, bulletproof windboard below the first roll (@10200’) and cranking winds!"
