Where the Sidewalk Ends

Incident Report

Attempted to climb "Where the Sidewalk Ends." Skinned up the lower approach slopes south of the approach gulley and observed several shooting cracks propagating <1m. Upon transitioning into the steep gulley fan (~45 degrees), we observed a small settlement. Several minutes later, we triggered a wind slab (20cm thick) settlement that propagated ~30m above us and slid. This slab stepped down to the bottom of the snowpack (70cm) and slid 300 vertical metres to the bottom of the path. One member of the party caught the edge of the avalanche and floated a short distance. The other member of the party was caught and carried to the bottom of the slide path. No serious injuries.
