A quick lap to Upper Humpy Creek Basin revealed a large natural avalanche which probably released shortly after Thanksgiving... I'm thinking the 29th or 30th timeframe. The avalanche fits the pattern of other slides both Ted and I have documented on the North Slope.
Of historic note... the piece of snow in the image above which remained intact, is the same slope that led to a tragic avalanche accident on Thanksgiving Day of the 2010-11 winter.
