Doug Chabot of the GNFAC investigates an avalanche that partially buried a groomer without injury to the driver. The slide broke on facets at the ground and was 2-3' deep, 100' wide, and ran 600' slope distance. It put 8' of debris on the roadcut. The slope was west facing at 7,500' and averaged 38 degree steep in the starting zone. #gnfacobs #avalanche #gvsa
