Snow Observations-Butte Area

Natural avalanche from the top of the popular snowmobile climbing spots on McDermott Hill in the Flint Range near Philipsburg. There have been several close calls and a fatality in this same path. It is named for the person who was killed in an avalanche there in the 70s. It appeared to be a wind load on the ridge that initiated the slide. In the background of a janky video, it appears there were other naturals as well. The slide ran an estimated 800 ft, but no other information was obtained.
