The were reports of
sensitive wind drifts on Thursday, including a large natural avalanche in
Snake Creek on an east aspect at 9,200'. The slope appeared to be wind-loaded from the sustained northwest winds on Thursday and estimated at several hundred feet wide and a crown 1-2' deep.
There were three serious avalanche accidents this past week with serious injuries with two that required rescues. The avalanches broke down over 2' deep into the layer of November facets. These avalanches occurred at low elevations below 8,000':
Tuesday - Pink Pine Ridge 7,800' North-facing 2-3' deep, 60' wide.
