Came across this natural avalanche on a northwest aspect. Apparently it was triggered from a natural avalanche up higher on a cross-loaded slope, and as the debris ran downhill, it sympathetically pulled out a larger/wider slide down low on the slope. Crown averaged 40-60 cms (16-24") and it ran on a layer of weaker snow from the Saturday storm. The starting zone appeared to have been cross-loaded from westerly winds.
