From email: "Natural avalanche from yesterday evening or last night.
North facing aspect, with an interesting 3 tiered crown beginning around 8900'."
Three avalanches were triggered 20-50' away from low-angel terrain above by skiers on Mt. Abundance.
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'."

Riders on 02/11/2024 observed two avalanches on the east side of Miller Ridge. These likely happened a few days prior near the end of a recent storm.
From obs: "Natural avalanches observed on east facing aspect of Miller Ridge on 2/11. Larger avalanche propagated widely on the north end of the ridge around 10,000 ft. Smaller avalanche further south on the ridge as well. "

Skiers in Middle Basin remotely triggered two avalanches while crossing below them. One was triggered by the party breaking trail, the second by a 2nd party from the skin track.
