These observations were taken on the south side of the house, opposite the usual observation location but in an area less prone to blowing and drifting, but not particularly sheltered either. The typical observing location had new snow depths of 2.5-4.0" as it is cut out of a block of snow with the full snow depth, and thus is very prone to drifting, especially with N or NW winds.
