More detailed information about the snowpack: 

New snow amounts in the area ranged from 10 to 20 cm. Newly formed wind slabs up to 50 cm thick were present near and above treeline in wind loaded areas. Testpit at the noted lat/long (N aspect, 8,310', 25 degree slope) yielded ECTN results with new snow from the past 24 hrs deposited on bare ground at the testpit location.
