General Observations

We climbed and skied from above the Devil's Thumb on 12/18/19. We dug a pit at around 3500' on a SW aspect on the ascent. The snowpack was 115cm deep and had two finger progressing to one finger density to the ground. A column test resulted in no failures (CTN). I pried the column off the ground and it stayed together and even pulled ground cover out with it. Encouraging to see a dense base layer after these cold temps, seems we may have enough depth to insulate against a deep facet layer for now.

The skiing was tolerable, wind board with a little soft snow drifted on top in places. It was also nice to top out above the inversion layer and get some warm temps in the middle of winter.
