Comments
Saw this on our way up Porter Fork. Was likely triggered remotely by a group of 2 skiers on an adjacent slope, but a small ridge separated the path, so was undetected. Bed surface was hard crust, with facets above. Slide was 2' deep and 100' wide, and filled the gulley with debris. Elsewhere on tour, collapsing was the norm. This slide illustrates connectivity of slab and weak layer uniformity due to the remote trigger.
