Comments
This picture has an avalanche west of the final chute in Tanner's, I included more pics of some others too. Snow down lower was pretty saturated and did not cool down much last night at all. Higher up was colder but the wind had moved around quite a bit of snow above 9000'. So mixture of issues going forward, dug a pit through on of the wind slabs, ECT failed on the new snow at 12 and 30cms down where the snow from before this last storm failed at 22. No propagation on either and poor shear structure as well.

Wet slide lower down in Tanner's. It was warming up when we went down around 10, had a couple of natural and skier made roller balls that were probably head-sized. Some light cloud cover kept the snow from heating too much once the sun came out.
Comments
Went further up canyon around Flagstaff later in the day, the sun was definitely having an effect on the snow but overall above 9000' all aspects were much less damp and none of the wind affected areas or cornices we tested reacted at all. I was surprised by this some, but around 11000' and higher could be entirely different.
