Observation

Description of Snow, Weather, and Avalanche Conditions:

Multiple natural wind slab avalanches observed on northeast aspect around 8500 feet. The crowns had been filled in by blowing snow. Most of the debris was not covered by new snow so we think the avalanches ran during the night between 10/25 and 10/26. No other signs of instability were observed during our tour.
