Winds seemed to only be moving snow at the highest elevations like on American Twin Peaks. At 10K ft the winds simply kept it cold but didn't move much snow.

I excavated a massive hole looking for variability in the stratigraphy (aka - the layering) and variability in my ECT results but couldn't find it. Also tried using the new SP2 Avatech Probe. Didn't work. Consistently got ECTP's with scores in the 20's. This has been somewhat consistent in other places I've been digging. Notably in the MIll Creek area and also in the Uintas. Snowpack depth has been consistently around 1 meter (3.28 feet). I've also been getting occasional ECTN's or ECTX's, but mostly ECTP. Maybe it's where I choose to did my pits. I'm hunting for unstable snow.

Are ECTP's in the 20's "false unstable" results? They might be for now. This is a conservative test which is good. It has a 20% false unstable rate but a very very low rate of false stable results. This keeps us alive. One studies has shown the ECT to have high variability during Moderate danger, and very low variability during low or high danger. Not surprising.
