Problem #2 Comments
Grauple pooling.
Saw 1 possibly 2 sildes that failed 2' ish down where the slope kinks. Goes from steep to flatter. Thick grey line in pit that is not as obvious/thick elsewhere where the grauple doesn't pool. Ran into Craig Gordon, suspect he will cover.

Threat and error management. The threat today was avalanches in the new snow. I managed the threat by keeping my angles below 30 and if steeper for a bit it, choose small low/no consequence terrain.
I had a nice talk with Uinta forcaster Craig Gordon, who I was excited to run into hard at work investigation a avalanche and was nice enough to share his knowledge!
Today I saw -
natural avalanche magically appear while I was converting.
cracking.
a lightning strikes twice slide (broke 6 inches then an hour later broke 2 feet deep in run-out of previous)
I intentionally triggered a slide
Lots going on today snow movement wise. Went from 0 slides to 5 in 4 hours, a new one every lap.
Basically high probability, low consequences. If you had to choose a day for a lesson from the dragon today might be a good day to pick maby, But by keeping the angles down I'd rather just take my lessons by talking to Craig, snow inside your eyelids doesn't sound that appealing.
