We noticed two skiers ascending the east end of Cardiac Bowl on the north aspect of Mt Superior around 1030am. We skied out of view from that slope for a lap and when we regained sight of that area we noticed a recent avalanche with the skiers' tracks alongside it. We never saw the skiers again- they'd boogied down after the close call - but spoke with another party who said the skiers had remotely triggered the avalanche while skinning. It wasn't clear to us where the skiers were in relationship to the avalanche's path when the collapse occured.
The avalanche gouged away facets to near the ground. It appeared that only a few inches of snow remained along the upper portion of the bed surface.
