CAIC Observation Report

air temp (F): 25; cloud cover: few; wind loading: light; recent snowfall (cm): 38; snow avail for transport: small smounts

Snow pit was Dug on N-N/E aspect at 10922’ with a slope angle of 19 degrees just above Reservoir Lake. Surface hoar was evident on snow surface from overnight and our height of snow was 138cm. We observed several distinct layers, including the surface hoar, a wind slab layer (“JanSlab”), our existing persistent weak layer (“christmas crust”), and depth hoar near the ground. We performed both an extended column test (ECT) as well as a propagation test (PST). The extended column test yielded no results ending in a score of ECTX. We did two propagation saw tests with a small reaction underneath the Christmas crust (PST 60/120 END)and a more reactive result underneath the depth hoar layer near the ground (PST 40/120 END).
