Observations
Snow was great for riding from 7,000 to 3,000 feet with snow getting dryer as we moved up. Snow was quite stable. However, on steep aspects above 6,200 ft below Cliff bands and trees there were naturally occurring dry loose (see photos). Riders also triggered dry loose D1 riding on the edge of steep gullies in the North Bowl. Right below the ridge line at 7,100-7,300 feet, the snow was noticeably wind deposited loosely slabbing together (pieces an inch deep and a foot square at most would form breaking trail), but was very light and fragile and would not propagate. Lightly snowing off and on throughout the afternoon.
