Natural slides in Hyalite Basin
These avalanches likely broke around 2/24/21 with other avalanche activity. One was above Hyalite Lake the others were, "Observed two dry-loose slides and one slab avalanche on the NE-facing slope of Peak 10,024 in the Shower Creek basin on Sunday (2/28/21) - all were presumably naturally triggered."

"Observed an old crown line and covered avy debris on a NW-facing slope looking SE from Hyalite Lake." Likely occurred around 2/24/21. Photo: K. Busby
Natural slides occurred on Peak 10,024 in Shower Creek basin
Observed two dry-loose slides and one slab avalanche on the NE-facing slope of Peak 10,024 (not sure if it has a local name) in the Shower Creek basin on Sunday - all were presumably naturally triggered. We didn't observe them slide. The slab avalanche may have been from the previous day?
Hyalite Lake
Observed an old crown line and covered avy debris on a NW-facing slope looking SE from Hyalite Lake.
Wet loose avalanches released in the warm sunshine on Tuesday, March 2nd. We expect many more in the coming days. Photo: S. Jonas

Hyalite canyon
Observed a very large deep slab crown on a N facing slope at approx. 8700 ft in the badin above Elevator Shaft. Seen from orher side of hyalite canyon.
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
