Today there are 100 National Monuments the vast majority of which are administered by the National Park Service; but others are administered wholly or partly by the U. S. Fish and Wildlife Service, the Bureau of Land Management, the U. S. Forest Service, the Armed Services Retirement Home, and the National Oceanic and Atmospheric Administration. However, not all National Monuments created by Congress are administered and operated by the Federal Government. Hohokam Pima NM is owned and operated by the Gila Indian Community, and the Poverty Point State LA is owned and operated by the Louisiana Office of State Parks.
Interestingly, of the 100 National Monuments that exist today only 71 were created by a president using the Antiquities Act, the other 29 were created by an Act of Congress. Typically, those created by an act of Congress were on private land that had to be purchased by the government or more often by private individuals who donated the land to the government after purchase.
The oldest to be created by an act of Congress is George Washington Birthplace National Monument in Virginia which was authorized January 23, 1930. The next four created by an act of Congress were all over the map: Canyon de Chelly in Arizona, Ocmulgee in Georgia, Fort Stanwix in the state of New York, and Homestead in Nebraska.
These five and most of the other National Monuments created by acts of Congress had long and difficult journeys involving many local people, Congressmen, and Senators before the legislation was passed. The story of the creation of Homestead National Monument of America is typical.
