14-15

Above Fairy Lake we had many large collapses as we toured on our skis.  The weak layer of facets at the ground are still unstable.  In this pit the facets were under a very dense wind slab and broke with ECTP15. Photo: A. Fauver

This pit was dug on a NE facing slope at 8,000 ft. north of Bridger Bowl. Facets near the ground continue to propagate in stability tests indicating an unstable structure. Photo GNFAC 

Two snowmobilers were riding north of Cooke City, MT along the Daisy Pass Road under Henderson Mountain just past the turn to the Miller Road. One rode through a gap in the trees to a gully that opened to a 37 degree slope above him. His partner remained on the road. He remotely triggered an avalanche and was buried about 5 feet deep, 100 feet from the road. The avalanche danger was rated HIGH on all slopes and an Avalanche Warning had been issued that day.
