National Park Service May 16, 2007 – Federal Register Recent Federal Regulation Documents

The National Park Service is proposing this rule to manage winter visitation and recreational use in Yellowstone and Grand Teton National Parks and the John D. Rockefeller, Jr., Memorial Parkway. This proposed rule would require that recreational snowmobiles and snowcoaches operating in the parks meet certain air and sound restrictions, that snowmobilers in Yellowstone be accompanied by a commercial guide, and proposes certain revisions to the daily entry limits on the numbers of snowmobiles and snowcoaches that may enter the parks. Traveling off designated oversnow routes will remain prohibited.
