Abstract: This device is designed to facilitate the ascent and descent by a back country or cross country skier on moderate to steeply inclined soft snow slopes. Its utility consists of its ease of installation and removal, and its exceptional performance as tested in prototype form. This device is unique in that it facilitates both ascent and descent. It is believed that no existing device allows for ascent as well as for safe, controlled descent thereby giving the skier the option not to ski down a slope if he does not feel he can safely do so.
