Observations

As our group was having lunch at the cat drop off we watched a high marking sled across the gully from us trigger this soft slab. The crown was notable and fortunately it wasn’t a long track . Slope angle was undetermined but looked to be in the area of 38-40 degrees . The toe was in a gully area and the machine never stopped after triggering. This cat ski zone we often call the Scarface area.
