Comments
The Southern 1/3 of Circle Awl released ~during the early morning. Bed surface was the most recent sun crust.
Up high on the ridge new harmless cornices building where I haven't seen them before, easy cornice stomping.
Upper slopes no instability, lower half of the east facing slopes released, I'm guessing from graupel pooling off the steeper slopes above. Howie clued me into the angle of repose yesterday, seemed to be spot on.
Old time upper BCC resident (plow guy) talking about the most single snow amount he's ever seen from one nights snow (seen bigger storms.)
