Dug at 7700ft on a protected north facing slope. Surprised to note a pretty distinct layer at the new/old snow interface. New year's layer was clear a bit farther down, with softer snow and graupel still present. Shovel tilt and shovel shear indicated good bonding in the new to old snow, as did the skiing in steeper terrain. Despite the F hardness sandwiched by 4F at the graupel layer, CT and ECT were both unreactive. Right side up snow otherwise.
