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 snowmobiler triggered an avalanche as she climbed up the backside of Crown Butte. As she descended the slope the avalanche broke and ran down the slope behind her. Thankfully, no one was caught or injured. Photo: CA
