From Northwest Avalanche Accident Summaries:

March 4, 2018

One splitboarder traveling in a party of 4 was killed in a slab avalanche that released off a sub-peak of Setting Sun Mountain near Mazama, WA. The slide released on a WNW aspect at 6900ft and ran 800 vertical feet. The avalanche (HS-AR-R4-D2.5-O/G) had an average crown depth of 28” (70 cm) and was approximately 230ft (70m) wide, breaking trees that were up to 6” in diameter. The avalanche failed on facets over a thin crust and stepped down to deeper layers.
