Special Regulations; Areas of the National Park System
The National Park Service is proposing this rule to manage winter visitation and recreational use in Yellowstone National Park for an interim period of three winter seasons commencing with the 2008-2009 season. The proposed rule would also establish the framework for the long-term management of winter use in Grand Teton National Park and the John D. Rockefeller, Jr., Memorial Parkway. This proposed rule would require that most recreational snowmobiles and snowcoaches operating in the parks meet certain air and sound requirements, and that snowmobilers in Yellowstone be accompanied by a commercial guide. It also proposes daily entry limits on the numbers of snowmobiles and snowcoaches that may enter the parks. Traveling off designated oversnow routes will remain prohibited.
