Northern Gallatin

Sled Skiing in Third Yellow mule... after an air onto the slope the impact from landing resulted in a fracture and failure to / near the ground... in addition, a remote trigger occurred on adjacent slope... 200-300 ft to the skiers right. No body was caught in either slide. Skier that initiated failure was moving at high speed and was beyond slide path before majority of snow movement began. Photo: W. Miller

This avalanche was triggered on Sunday, 2/28, when a skier released another slide 2-300 feet away. It broke at the same time. No one was caught. This was in the Third Yellow Mule on Buck Ridge.  Photo: W. Miller

"Saw this crown the morning of 2/28 from G1 while climbing." Reported to GNFAC (earlier in the week). Probably slid last week during other large slides nearby. Photo: V. Beineke

This was observed from the genesis area in hyalite. It was on the north east facing Bowl off elephant mountain about 800ft above the un named wall. It looked like it was about 200-300ft across.

Skied out on an open slope adjacent to Hyalite creek today. Dug a pit on an E facing 15 deg slope at ~7800ft. No notable results in CT or ECT, but when converting to a deep tap, DT9 on the facets at the ground with a big sudden collapse. Pretty consistent with other pits I've dug up in Hyalite in the last week. Basal facets are still very weak and unconsolidated. Did not see any other signs of instability but would not expect cracking or collapsing with the problem layer buried so deep (~6 feet in this pit).
