Snowmachine use in Alaska has increased substantially during the previous decade. In addition, innovations in the design and performance of these vehicles has allowed riders to travel farther and faster per hour of riding time than was possible in the past. These design innovations have resulted in the elimination of de facto natural barriers (i.e. steep terrain) to snowmachine access. A potential consequence of this trend in use and these technological changes is increased impacts on the resources of Denali National Park and Preserve, including harm to the vegetation resources.
