I dug a pit on the West and North aspect of Tenderfoot.
1) 2300', west aspect, 30deg, 2 crusts in upper snowpack. 15cm down the second crust had test results: CT12Q2, ECTX. Below the crusts is a cold layer of facets. The bottom 30cm of the snowpack is previously frozen/dry basal facets that had edges and round corners.
2) 2500', north aspect, 30deg. 2 crusts in upper snowpack. 20cm down the second crust had test results: CT7Q2, ECTX. Below the crust is a cold layer of facets. The bottom 5cm of the snowpack is previously frozen/moist basal facets that had edges and round corners. Interesting.
In both pits: The warm days we had did heat up the snowpack quite a ways down. There is a ~40cm layer of facets below the crusts that is quite a bit colder, probably forming post warmup when temps dropped.
