Often called "the conservation president," Theodore Roosevelt, made an impact on the National Park System well beyond his term in office. As President from 1901 to 1909, he doubled the number of sites within the National Park system and signed legislation establishing five new national parks: Crater Lake, Oregon; Wind Cave, South Dakota; Sullys Hill, North Dakota (later re-designated a game preserve); Mesa Verde, Colorado; and Platt, Oklahoma (now part of Chickasaw National Recreation Area). However, the Antiquities Act of June 8, 1906 enabled President Roosevelt and succeeding Presidents to proclaim historic landmarks, historic or prehistoric structures, and other objects of historic or scientific interest in federal ownership as national monuments.
Roosevelt did not hesitate to take advantage of this new executive authority. By the end of 1906 he had proclaimed four national monuments: Devils Tower, Wyoming; El Morro, New Mexico; Montezuma Castle, Arizona; and Petrified Forest, Arizona. He also interpreted the authority expansively, protecting a large portion of the Grand Canyon as a national monument in 1908. By the end of his term he had reserved six predominantly cultural areas and twelve predominantly natural areas in this manner. Half of the total land area was initially administered by the Agriculture Department and was later transferred to the Interior Department, since the National Park Service would not be created until 1916.
Later Presidents have used the Antiquities Act to declare national monuments. Many national monuments remain, while others have been enlarged into national parks or otherwise reclassified by Congress. The Antiquities Act is the original authority for nearly a quarter of the 400-plus areas composing the national park system.
Recalling his legacy, Theodore Roosevelt is now commemorated at six units of the National Park System. Theodore Roosevelt Birthplace National Historic Site in New York City, Sagamore Hill National Historic Site in Oyster Bay, New York, Theodore Roosevelt Inaugural National Historic Site in Buffalo, New York, Theodore Roosevelt National Park in North Dakota, and Theodore Roosevelt Island in Washington, DC, all trace his career and memorialize his contributions to America. Of course, Theodore Roosevelt is one of four Presidents gracing Mt. Rushmore National Memorial in South Dakota. The National Park Service is honored to administer these park sites, and the many others Roosevelt made possible during his storied career as a conservationist.
