Warming quick in the Bridgers

Up on the Ridge this morning, the recent snow had developed a 3-5 cm crust, and remained moist underneath. No active signs of instability while the snow remained cold, except for the various crowns from slides which broke during the storm (Avalanche Gulch, North Bowl, etc.), and lots of rollerballs from yesterday. Within an hour of sunrise the surface crust began to break down, and small loose releases were beginning to rain down from cliffs and around the large cornices. The cornices, some reaching the size of a small car, were already visibly sagging and many smaller cornices easily released under body weight.

Notes

From email 5/8/24: "A few snaps from today. Observed several D2 slides between sluice box and the nose. I didn't see the toe of these slides, but it looked like there were running with some speed into mid elevation terrain. Slabs were most common in winded terrain, but slides flanked out on new/old interface and 4/26 crust (these layers are not very far apart) even in sheltered middle elevation terrain. Visibility was poor, but I'd expect to see similar large slides in steep, winded terrain

4/26 crust down:

55-60cm at 6500

65-70cm at bridger mid 

75+cm at ridgeline"
