From email: "Saw debris from a fairly recent slab avi that slid in lookers right of arrowhead bowl (tough to see in photo but the crowns appeared to be a couple feet deep).  There were a bunch of other debris piles on similar aspects but I was too far for photos.  They probably slid on Friday night [4/22/22] as the debris had a few inches on top. "

From email: "I'd hypothesize that this avalanche might have happened sometime yesterday.  There was a light rain event on April 21, and an associated widespread (but minor) wet loose avalanche cycle on steep northerly aspects the same day.  And it appears from the photo that the slab avalanche might have happened subsequent to all the roller ball/ well loose activity.  Yesterday was very warm here also, with a high of 47 deg F at the NE Entrance at noon."

Skiers reported shooting cracks from their skis while ascending the terrain at Bridger Bowl. The group later remotely triggered an avalanche from 100'+ away that ran through the "Pearly Gates" and "Patrol Chute".

On 4/18/22 near Cooke City we witnessed natural rollerballs and pinwheels by 11 am, and a couple wet loose slides below cliffs on southerly slopes around noon, and were able to easily trigger pinwheels on west-southwest aspects around 1230-1pm. Photo: GNFAC

On 4/17/22 near Cooke City we saw a couple natural 2-4" deep, 10' wide slabs on small hills lower down (pictured); natural 6-16" slabs on heavily wind loaded slopes on east aspect of Sheep Mtn., north face of Miller and east Wolverine mostly D1-1.5 (no photos); and two skier triggered D1.5 loose snow/storm slabs on the east aspect of Miller Ridge (no photo).

From obs 4/16/22: "My partner and I observed relative instability (ECTP 14) on a thick ice crust on a SW-facing slope at the base of Henderson Ridge. In addition to the propagation, there was a fracture at the new snow interface roughly 10cm deep, which was noticeably less consolidated than the snow between it and the buried sun-crust. We did not witness any cracking or whumphing along the skin track and decided to ski a similar aspect. As we quickly navigated across a steep, 33-degree slope, two small loose slides broke from under our cuts, each roughly 10' across and traveling 30'. Each of these broke on the shallower new snow that rendered a fracture in our ECT."

From obs 4/17/22: "Ski cut on belay a SS avalanche out of the start zone of this N facing slope in Sheep Creek basin. The crown was 4-16" deep and broke into the rocks on skier's right, as well as skirted the bottom of the rock wall skier's left. Winds along the Mineral ridge were moderate gusting strong from the south with active transport observed."

We saw this natural avalanche on the Fin that occurred overnight on April 17th. It was the result of new snow and strong winds over the weekend. Photo: GNFAC

From Obs: "Small wind slab on the ridge between Bridger Gully and North Bowl. Only about 2” of snow and moderate wind (Monday at 4pm) when I got this small slab to crack and run on the old snow crust. Higher up drifts were over 2’ tall." C. Oshiro-Leavitt

From obs 4/7/22: "We observed a small cornice triggered avalanche (R1-D1.5) from a wind-loaded gully off Peak 10602 that likely slid during or soon after the recent storm cycle. The slide had a crown of approx. 8-15in, and ran ~300ft. ... We also observed several other instances of recent cornice-fall in the basin."
