The red line marks the skiers track and the "x" is the approximate location where he jumped over the rocks. He triggered the 40 degree steep slope which carried him down the gulley and partially buried him. His partners skied a line behind the camera. The avalanche broke on a layer of sugary facets that were supporting a three foot thick hard slab. The rocky area acted as a "facet garden" which made weaker and more unstable than the surrounding snow. Photo: GNFAC
