This is the snow profile of an avalanche that had been reported one day before (utahavalanchecenter.org/avalanche/58378). The reported slop angle is right at the crown, right where the slope transitions from a mellower slope into a steeper slope between trees.
Avalanche was 100m wide and 300m long, hard slab. Trigger was a skier: AS. D2 in destructive potential. R4 in size since it filled the space between the trees. Release was within the old snowpack: O.
