Red Flags Comments
Still a fair amount of cracking and collapsing today with a few good audible whoopfs and a couple of collapses where you could actually feel the slab drop under your feet.
Avalanche Problem #1
Type
Persistent Slab
Problem #1 Comments

Where we traveled, in low, mid and higher elevation sheltered terrain, the persistent slab issue was the biggest and really the only problem we had to deal with. We were finding buried surface hoar at all elevations traveled.

Comments

Long running cracks.

Traveled from 7400-10K, north half of the compass.

Still finding lots for buried and preserved surface hoar.

The storm slab is becoming more cohesive and we were getting large areas of connected snow to collapse and I can see a potential for avalanches becoming larger due to the increased connectivity of the slab. ECT and CT scores were in the easy to easy/moderate category with clean shears. Sun and warmer temps will be the other factor to be aware of in the next day or two.

Still feeling like there is a considerable danger in terrain similar to where we were traveling, places where surface hoar formed but wasn't knocked back by the wind. Tricky conditions.
