Avalanche

Saw numerous old avalanches from the Late January storm cycle. A few D1-D2 wet loose in each of the following: the Skyline Lake highway paths, Lichtenberg SE face, above Lake Susan Jane, and White Pine Cirque. Notable D2.5-3s from control work at the ski area and in Rock Mtn/Nason Ridge, just west of West Camp.
