On my walk up to divide today 3/28 I noticed a few small storm slabs that broke on the west side of the main fork of hyalite off the summer trail. This area had similar storm slabs that broke back in mid February during a large storm
up in the alpine there were no avalanches to report

From IG:
Think this was a recent natural up buck I saw today. Didn’t get close enough to see but looked like it was a big crown… down low 8900ish SE

Notes
Two large, widely propagation fractures visible through a hole in the cloud cover Monday A.M. from Bridger Canyon Dr. Upper slab failure evidently stepped down to a deeper layer estimated 400' below upper crown. Both crowns appeared to be similar depth. Also visible were debris toes further to the North that had run mostly full path. Looked like it was already covered up yesterday (tues).
A second ob via phone message:
A large natural avalanche occurred on the north summit of Bridger Peak yesterday (Monday, 27 March). The crown line was complex.

Uneventful day. Rode through all three yellowmules, McAtee Basin, and the heads of Muddy and Bear Creeks. Saw no recent avalanches or other signs of instability. Dug two snowpits on E and N aspects at ~9400 ft. About 12" of snow from last weekend with 1.3" snow water equivalent. ECTN14&16 under the new snow. No other results.
Snowing lightly with overcast skies and calm winds. We'll be paying attention as it starts snowing tomorrow, especially if the wind picks up as forecasted.
