Notes
From Obs: "On the morning of Sunday February 6, a snowmobiler triggered a slide in new snow on the SW face of Sheep Mountain. The slide triggered remotely while the rider was lower on the slope and he was not caught (the visible track is not from the rider who triggered the slide, his track was buried in the debris field). The crown was about 18" deep and 75 feet wide and the slide and the slide ran about 250 feet."
