Lots of Pine Canyon wet slides. A few feet below the summit of Bob Steward Peak on its east face at 9,300 ft, I intentionally triggered a slide about 1' deep and two ski widths wide. It ran ~100' feet down the slope. Lower down at 8,500 ft (marked on the map), a much larger 150' ft wide natural wet slide ran 400' or 500' vertical and piled debris 1' to 3' high. The trigger looked to be point releases off cliff faces above. This slide took out the top 1' of snow. A few hundred feet vertical further down, there was another larger natural wet slide, 200' wide that ran 400' to 500' vertical. Skiing down next to this natural slide, I unintentionally triggered more snow to slide that ran down to join the main debris pile. And then lower still at 7,800 ft or so, there was another large natural wet slide that started in a steep gully. Again, 200' wide, ran at least 400' vertical and finished with a debris pile up to 5' high. All the naturals were on NE aspects. Date of occurrence of the naturals unknown.
