From obs: "The southwest corner of the cirque slid on the storm slab and broke 1200-1500’ wide, an east aspect had a crown that exceeded 6’ in places, and the south face of Divide Peak broke 2-6’ deep and ran full track. I observed no collapsing or cracking, but the signs of instability were still pretty clear."

I skied around the little hills in the basin south of Divide Peak today, and saw quite a bit of recent activity. The southwest corner of the cirque slid on the storm slab and broke 1200-1500’ wide, an east aspect had a crown that exceeded 6’ in places, and the south side of Divide broke 2-6’ deep and ran full track. I am not sure what the bigger slides failed on, and would not feel particularly confident guessing, but things up high are active. We dug a pit on the south side of Palace Butte on Saturday and found what appeared to be a very stable snowpack, but seeing Divide slide on the same aspect is evidence that a snowpit is only part of the puzzle. I observed no collapsing or cracking, but the signs of instability were still pretty clear.

From FB: "Saw recent wind slab natural on NW facing start zone of tube south of Titanic. Ran into titanic approximately 500' vertical where tubes join. D2 in size. No other signs of instabilities noted." Photo: B. Zavora

Observed a dozen or more collapses while skinning up south-facing aspect between 7500 and 8300ft. Noted shallow snow depth of 2-3ft where collapses were occurring.
