This explosive triggered avalanche occurred on the South Face of Lone Mountain in the Otter Slide above Lenin. Most slides breaking deep in the snowpack have occurred on north aspects and this was the first one so far on a south aspect. The ski patrol did not think it could have been triggered by a skier but that's a chance they can't take. Photo: Big Sky Ski Patrol

    • This small natural avalanche was observed in the northern Gallatin Range near Hyalite Peak. It likely occurred during or immediately after the storm earlier in the week. This slide stayed confined to the storm snow and did not step down to deeper layers. It remains possible for skiers or riders to trigger similar avalanches in steep terrain. Photo GNFAC
