TESTS: CT9 ... ECTP11 breaking at what is likely the Christmas storm interface. (Tests were performed on Tuesday, Jan. 9 before this area of the Uintas saw new snow overnight or today (Jan. 10). Our pit was due north @ 9,400 ft with a slope angle of 30 degrees).

Problem #1 Comments
There are facets by the shovelful out there. Pretty amazing stuff, and hard to miss. There's not a huge, cohesive slab where we were, but new loading from the recent storm could definitely tip the scales, especially in steeper terrain. Basal facets (bottom 1 to 2'') were almost rock hard.

Increasing Danger
Problem #2 Comments
There is definitely new snow for transport right now. If the new snow isn't enough to tip the scales, the extra wind deposited snow could be for sure.
