Cooke City, natural avalanche activity
From email: "Natural avalanches observed near Cooke City today. At least 3 big PWL/ deep slab avalanches. All northerly aspects, mid elevations.
Also, observed one upper elevation north facing slide that looked more like a storm slab."
Wind slabs in the Bridgers
From obs: "Today I saw evidence of Multiple N-R2-D2-I avalanches in the fairy lake zone. All three were NE facing, around 8800’. 2 slabs in Fraizer basin and one in the basin to the south. All three looked to be from 3/3-3/4 storm cycle"

Natural Avalanche in Cooke City
East face of Republic Mountain above Erma Mine Cabins. 8800 ft natural avalanche just below the ridge. 3-4 foot crown, Apx 100’ across, ran approximately 1000 feet down the creek bed. Appeared to be from earlier in the morning possibly when the avalanche slid off the north face of Republic, as it had a light dusting of snow over the debris. This start zone was just over the ridge from the North facing 9:14 am avalanche but I don’t think the start zones were connected.

We skied in the love chutes and Fraizer basin today with No collapsing or cracking.
Mixed Messages on Cinnamon Mountain
Toured up to the Cinnamon Mountain Lookout today. In a small meadow along the trail I got a small whumph, with a crack propagating out 5-10 feet all around me. HS was around 30-40 cm in this meadow. HS rose rapidly with elevation and I had no other large collapses throughout the day, but noticed some localized cracking in recently formed windslabs, and rapid warming of the snow surface in the sun all day. I dug a pit about 200' down from the summit, directly south facing, and got unremarkable test scores from a scary structure (full profile is in snowpilot). With the several warning signs I had seen, I chose to take my test results with a grain of salt, and ski a conservative line.
