NO. Yellowstone National Park is America's first national park and was established in 1872. It is maintained by the National Park Service. Prior to the establishment of the National Park Service, the U.S. Army protected Yellowstone between 1886 and 1918. Fort Yellowstone was established at Mammoth Hot Springs for that purpose.
