WASHINGTON (CN) - The National Park Service will limit the number and type of snowmobiles allowed in Yellowstone National Park, Grand Teton National Park, and the scenic highway that joins them, until a permanent plan is created.
The rules also require that most recreational snowmobiles in the park meet air and sound emissions requirements, and that snowmobilers and snowcoach riders be accompanied by a commercial guide. The rule sets daily limits on the numbers of snowmobiles at 318, instead of 720, and snowcoaches at 78, and requires that recreational snowmobiles on Jackson Lake be for the sole purpose of accessing ice fishing.
The vehicles also must be of the best available technology. The makes of such snowmobiles are Cat, Bombardier, Polaris and Yamaha, according to the National Park Service's Web site.
Traveling off designated oversnow routes remains prohibited.
