weather was clear and calm. medium winds at summit, temps just below freezing. I experienced frequent whumphing from 7800-8200ft, about 15 meters in diameter. I had two more whumphs around 8600ft about 20 meters in diameter. I traveled on low angle ridges on mostly NE aspects. Quick Pits: Pit 1: 8000ft south aspect, shaded snow height: 48cm snow surface: 3-5mm surface hoar layer of concern: 10cm basal facets 2-3mm CT score: 14 (M) sudden collapse Pit 2: 8400ft 60degrees NE snow height: 60cm snow surface: 3mm surface hoar layer of concern: 10cm basal facets, 3mm CT score: 11 (M) sudden collapse Pit 3: 8800ft 45 degrees NE snow height: 90cm snow surface: 3-5mm surface hoar Layer of concern: 15cm basal facets 2-3mm CT score: 21 (H) sudden collapse Pit 4: 9200ft 65degrees NE snow height: 50cm snow surface: firm, windboard layers of concern: 10-20cm from surface NSF 1-2mm; 35-45cm depth hoar 2-3mm CT score: 12 (M) sudden collapse Travel in steeper terrain above 35 degrees is not recommended. New snow will fall on large surface hoar/NSF. Coverage on solar aspects was very thin.
