YELLOWSTONE | America's First National Park
Protection of the large wilderness area around what the Native Americans called Yellowstone was accomplished by the Yellowstone Park Act of 1872, making it the first National Park in the world. This was not only the origin of the United States National Park Service, but it served as a model for many countries in the conservation of wild and scenic places.
