AST 2 group went to check out the crown of the old avalanche in Pleuman Basin. We suspect it went naturally around January 14 (9 days ago). The crown is mostly filled in, but we estimated that the depth of the slab was 55 cm, likely a PWL layer from early January. The width of the crown was about 80m and it ran roughly 150m. The debris is still visible and was a healthy size 2.0 avalanche. The slope was 34 degrees at its steepest and 31 degrees near its right flank. NNE aspect, 2040m. Large opening halfway down a mostly treed slope.

Snow conditions were: Powder, Wind affected. Weather conditions were: Cold, Windy. We rode: Mellow slopes, Steep slopes. We avoided: Alpine slopes. Riding quality was good.
