We found the 12/1 crust to be holding strong at 2400', with hardly any faceting and still pencil to knife hard. With calm to light winds for the past few days, wind slabs were stubborn, but we were still careful around steep terrain near ridgelines.
Snow depth increased dramatically with elevation (and previous wind exposure). Here are some average depths measured at several elevations through the day:
2000': 90 cm (~3') deep
2400': 180 cm (~6' deep)
2600': 210 cm (~7' deep)
4800': 365 cm (12' deep). *this location has likely seen some wind loading this season.
We dug a third pit on a NW aspect at 4800'. We only dug down about 3' deep, and the upper pack was looking strong. The snow gradually changed from 4-finger to pencil-hard with depth, an we did not get any unstable test results (ECTN21 about a foot deep, below an old wind slab).
