Notes
Photo attached of a fresh natural avalanche, just south of Cooke City today. It appears to have run last night or this morning. (photographed at noon)
It's on a NE aspect, about 8100', directly above the ice climb known as 'Silver Gate Center'. I'd estimate the crown to be about 10" deep and 30' wide.
New snow: 3-8" in last 48 hrs. Lots of rimed forms.
No collapsing. No other slab avalanche activity to report.
Minor cracking of fresh wind drifts along the ridgelines today.
Also, the sun came out for a prolonged period late this morning, and created a m/f crust on steep solar aspects (primarily SE aspects). Temperature in Cooke was about 32F at 4pm.
