23-24

From BSSP 1/20/24: "There were large avalanches observed on Cedar Mountain, on northerly aspects. Slides appeared to
be running on basal instabilities deep in the pack."

Skied beehive basin and dropped into bear basin early this morning before the warm up, about 1-2" of fresh. In a early morning pit on the bear basin side near the top of the ridge we didn't get propagation but got cracking on hit 5 of our ECT. Noted a slab over facets buried ~ 50 cm from the bottom, with another slab and facet combo below that to the ground. ~90 cm total depth. As it warmed up other groups reported collapsing as they came up and we also saw the aftermath of a remotely collapsed cornice.

I toured in beehive today around the wilderness boundary and summer trail, riding and digging a pit on the E aspect (left side)as I was skinning toward the lake. There was about 90cm where I chose to do my profile.   Got CT 2 SC Q2 shear 70 cm down. I got ectp11 at 30 cm down. Talked to a seperate group of 2 splitboarders that came up skinning behind me, they had just dug a pit probably 50 ft below me, they also got ectp11. I saw a skier triggered slide on Tyler’s hill (lookers right of prayer flags gully), as I skinned in (ss-as-d1.5-r1-u). It looked  like it propagated across about 25 ft and just pulled out on the single roll over, I didn’t get real close, and figured a picture from that distance with trees in the way might not show much. Had skin glopping going on, most aspects on my split ski out had a crust on them, but that’s lower elevation.

From obs: "South of Cooke City numerous avalanches were observed on E, W, and Northern aspects. These all likely happened during or following a recent storm on 01/18." Photo: BPG
