From obs: "No details, came upon them while riding and making observations of the terrain. One was North-Northeast, the other was North-Northwest facing. Across the drainage from each other. Also, notice three other small avalanches on a west facing slope, about two miles east of the first two. All five were on slopes well over 30. In the centennial mountains, close to the continental on the Idaho/Montana border."

From obs: "We observed three similar avalanches on Mt Abundance today (2/11). All were at about 9,900' and on NE-NW aspects. We were able to safely look at the crown of the first one, which was ~150' wide, 55cm deep, and with an HS of 145. It failed on 1-2 cm buried surface hoar. The other avalanches were on shallow unsupported rocky terrain. All were remote triggered from low angle terrain above, 20-50' away. One of the avalanches sympathetically released a gully and ran 800'." Photo: A.

A pit in the flank of an avalanche above Hebgen Lake. The stripe in the picture delineates the new snow over the unstable, old, faceted snow. This interface is where avalanches are occurirng. Karl Birkeland was using his 100 cm long Norwegian Battle Saw...a bit overkill. Photo: GNFAC
