Comments
Group of 3 snowmobilers coming through a heavily trafficked area, the first rider went to descend the route, roughly 1/4 the way down the slope above broke loose, it appeared to be a sympathetic trigger as he was well below the fracture line. There were track marks from a previous group who had high marked the slope earlier in the day. The slide ran through the slight gully we were riding down to the bottom. The first rider was not caught in the slide, myself and the other rider were at the top maintaining distance while coming through the area. The last two photos have our route marked in red.
