Observations
Fresh snow was very soft and sluffed easily, but interface below held up on W/SW aspects on Red Mountain above 4500'. Quick hand pit around 5200' on SW aspect showed about 1-2' of soft snow that fell off easily, crust below appeared well bonded. Observed wind loading on South ridge of Snoqualmie Mtn and Kendall Peak. Tested small wind feature at 5600' West Aspect on Red Mountain that almost instantly failed triggering a small slide of the new snow + wind loading but crust below held up. Warming in early afternoon - crusty around 4400' and below on South aspect of Red Mountain
