Special Regulations; Areas of the National Park System, Yellowstone National Park

概要

The National Park Service (NPS) is proposing this rule to establish a management framework that allows the public to experience the unique winter resources and values at Yellowstone National Park. The proposed rule would provide a variety of use levels and experiences for visitors by establishing maximum numbers of snowmobiles and snowcoaches permitted in the park on a given day. It also would require that most snowmobiles and snowcoaches operating in the park meet air and sound requirements and be accompanied or operated by a commercial guide.
