Observer Comments
Weather
Bluebird day. Winds calm at Glen Alps PL but blowing from 180@15-20G22 on top of Blueberry Knoll. At 1500 Glen Alps weather station showed 47deg. At same time was 39deg at 2400ft on Blueberry. In some locations snow warming rapidly and sticking to skins.
Snow surface
On the flats found very large Surface hoar blades (pic) in sheltered areas overlying 10 cm of new snow from last Sunday’s storm on top of 30cm of rounds. This snow made for pleasant turns on the run back out to GA. This transitioned at approx. 2400ft to windboard/sastrugi on top of Blueberry Knoll (pic).

Did quick pit near base of snow-loaded slope at 2430ft on the NW aspect of Blueberry Knoll.
