From email: "Saw this very large avalanche on Climax. The crown looks fresh, so it likely occurred the day or night of 4/1?
Hard to tell but the crown looks to be about 4-6’ deep at its deepest. The debris ran to the creek.
E aspect at 10000’." Photo: N Hance

Pit to ground in Beehive Basin

Date
Activity
Skiing

We dug a pit to the ground (260cm) on the west wall in Beehive Basin to target observations for the Deep Slab problem. Attached is a SnowPilot graph of the layers, hardness, and grain identification. We performed a PST but did not get any results on the deeper facet layer, possibly due to the column not being fully isolated in the 260cm pit.

Natural Avalanche on Climax Path

Date
Activity
Skiing

From email: "Observed very limited terrain due to vis. Saw this very large avalanche on Climax. The crown looks fresh, so it likely occurred the day or night of 4/1?
Hard to tell but the crown looks to be about 4-6’ deep at its deepest. The debris ran to the creek.
E aspect at 10000’.

There were also several smaller soft slab avalanches that ran on the lookers right side of Climax.

On 4/1 we had a large collapse on a SE aspect at 9800’ where the MF crust was present under 60cm of new snow.

Winds were L-M with consistent gusts to S on Saturday."

Recent Natural Avalanche near Cooke City

Date
Activity
Skiing

From Email:

"Observed a fresh natural avalanche this afternoon on Woody Ridge. The avalanche occurred on a NW aspect, around 9200' (likely last night). I'd estimate the size to be 1-3' deep, and about 100' wide. 

No other avalanche activity observed today.  (ski tour up Republic Creek this morning, low visibility while I was up there).

No collapsing. Minor cracking of the fresh, dense wind drifts, though they felt quite stubborn.

New snow:  about 10", dense/ rimed forms."

Big Avalanche Crown, N. Absaroka Range

Date
Activity
Skiing

From email: "Saw this recent crown while xc skiing out above Mill Creek today.  It's on the east-southeast aspect of Peak 10526 east of Emigrant Peak at ~10,200'.  In what I like to call the Arrastra Ridge Avalanche Observatory Plot*.  The photo is taken approximately 5 miles in line of sight from the crown.  It is roughly 1000' wide.  If I had to guess, the crown is 10'+ tall—definitely a very destructive avalanche. I won't venture a guess on the rating.  I'd bet good money it ran all the way to the lake at the head of Burnt Creek and rearranged some timber.

*If one wanted to create a laboratory for observing large, regularly occurring naturally triggered avalanches, this would be one of the best locations in SW MT."
