Localized collapsing in some areas, especially around alders.
Around freezing, S wind 5-10 knots, broken skies.
New snow, wet with a bit of rain at the road, heavy above 1500 ft or so.
We dug three pits at 2330 feet on an east facing slope with slope angles between 26-28ยบ. Notable results included CT4, CT1, and CTV on on the ground. The final test column slid about 6" as soon as the saw hit the ground to isolate it (see photo). Basal facets were less reactive in extended column tests with ECTN19 and ECTN16 at the new/old snow interface at 70cm from ground. There was a lot of spatial variability in the amount and quality of the basal facets. Wind had clearly been transporting snow, but wind was calm in the trees and had not influenced area where we dug. In general, snowpack was right side up except for the basal faceting. Tried to trigger a S facing test slope, but could not.
