Signs of Unstable Snow

None reported

Observations

Strong, impenetrable concrete and grass crust buried approximately 25 cm, suspect to be pre-2/13 layer. New snow appeared to bond well to lower crust, but several spots showed potential for glide avalanche on weak oil and sand layer. Compression test (CTN) and extended column test (ECTX) both showed no fractures or propagation. No signs of instability were noted, so we dialed it up into advanced terrain. Dravus Couloir is definitely in, top to bottom. The backside provided amble coverage as well, allowing us to drop into the village for Apres. No whumphs were heard all day, only whoops and hollers.

Media

Excellent coverage throughout on all slopes, all aspects. Elevation 300ft yielded ample PPsd precip throughout the day.
Depth approx 25-30cm. Continuous accumulation (moderate S2) throughout the day. Compression test (CTN) and extended column (ECTX) both showed no fracture.
Crowded hills today with various multi-sport users. Watch out for sharks as well as small children on sleds!
