Quick report
Widespread avalanche activity on the back side of Seattle Ridge, including very wide propagating avalanches in Jr's, below the weather station, Main Bowl, and Warm-Up Bowl. Many of these were natural, at least one was suspected to be triggered remotely from on top of the ridge. Some were over 1,000' wide, and most were around 1-2' deep. These likely failed on a layer of buried surface hoar that was buried by the Thanksgiving storm.
