Comments
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.
