The Friends of the Avalanche Center, in partnership with the City of Bozeman, put in a Beacon Park at Beall Park. It is located on the north side of the Beall building between N. Bozeman Ave. and the ice rink. Stop by with your avalanche transceiver and do a few practice rescue drills. Your partner will thank you. Photo: S. Regan

This natural avalanche was likely triggered by a falling cornince in the last day or two. The slope is in the Wilderness and was seen from the boundary. Wind drifted snow is a concern in this area. Photo: GNFAC

From Obs: "This slide on the ridge extends north from Blackmore above Blackmore lake. The slide was on a north-facing slope around 9,100'. The crown looked multiple feet deep and either meandered, partially hidden from view, by another ridge or a substantial second avalanche a hundred feet away."

From obs: "Observed 2 natural avalanches, both on the basal persistent layer I would guess. one maybe a week old, partially filled in (SS-N-D1R2-O), and one that ran in the last 24 hrs (SS-N-D1.5R2-O) on a SE aspect, 35 deg at 8200 ft. I thought it was interesting given the lack of new snow and seeming lack of strong winds in this area." Photo: S. Hennessey

From email: "Observed natural deep slab probably happened overnight with the strong winds... snowpack in the area was about 3-5’ deep mostly 4F with 20+cm of F depth hoar at the bottom... obviously not strong enough to support the wind-load." Photo: T Thorn
