Avalanche Details

We were riding along Seattle ridge playing in the rollers around Little Sweden. No natural or human triggered slides seen going in around 11am. Crested a roller and saw the big slide which I suspect was remotely triggered 300-400 yards away. This was a ESE facing slope. Did not see it slide so I’m not 100% positive. This was on the leeward side of the peak where there snow loaded during the winds. 10-15mph winds at the time. On the way out we saw a recent slide sometime between 11-2pm next to Widowmaker, likely remotely triggered by snowmachine. South facing slope.
