Problem #1 Comments
As much as we'd like to think that the load of the new snow over the Oct facets is adjusting to the weight, it seems like it's not...yet. We got a big whoomph as we approached the ridge, and though there was some wind loading and minor slab development going on, the whoomph seemed pretty deeply-rooted. We chose not to go up to the ridge and tickle the sweet spot but instead stayed in the trees and on the lower-angle terrain. The crack that it created was small (see pic), but spread pretty far

Problem #2 Comments
There was enough of a chilly breeze out of the SW coming over the ridge that a wind slab was forming, but wasn't too deep/scary. However, a small windslab might have the potential to create enough energy for a bigger step-down to the weak facets near the ground?
