Yellowstone National Park The latest news on snowmobiles in Yellowstone! Snowmobile use threatens wildlife, wildlands Bison and snowmobiles in Yellowstone National Park. Often described as "America's best idea," Yellowstone National Park was set aside by Congress in 1872 to protect its wildlife and natural wonders for the enjoyment of all Americans - past, present, and future. Located in the rugged mountain country of Montana, Wyoming and Idaho, Yellowstone is one of the last remaining vestiges of American wilderness in the lower 48 states. Yellowstone is home to hundreds of wildlife species including bald eagles, trumpeter swans, elk, bison, bears and wolves. The region also contains the largest and most diverse collection of geothermal features in the world and is the headwaters to three major river systems - the Yellowstone, Snake, and Green.
