8th person on this slope, collapsed the slab near a rock feature buried under the snowpack. Fortunately, everyone came out on top at the end of the day.

 

Top image- overview of slide path

Middle image- likely trigger point... rock that was barely covered with very weak snow.

Bottom image- unlike recent avalanches in the Wasatch which have failed near the prominent dust layer, Uinta avalanches are breaking beneath that, on a facet/crust sandwich.
