Theodore Roosevelt, often called 'the conservation president,' impacted the National Park System well beyond his term in office. He doubled the number of sites within the National Park system. As President from 1901 to 1909, he 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 another Roosevelt enactment had a broader effect: the Antiquities Act of June 8, 1906. The Antiquities Act 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.
