Francis P. McManamon examines the origins of the Antiquities Act of 1906 that President Theodore Roosevelt and his successors used to safeguard natural and scientific sites across the United States. McManamon asserts that it was threats to ancient archaeological sites across the American Southwest that led to calls for greater government intervention, and he highlights the case of the Casa Grande ruins in Arizona. McManamon notes the work of private organizations, government agencies, individuals, and members of Congress, most importantly Congressman John F. Lacey of Iowa, who worked to save important sites before the passage of the Antiquities Act. McManamon traces the slow path to passage of the Antiquities Act, and he highlights its important text and provisions. He notes how Roosevelt used the act to set aside eighteen national monuments, and he asserts that Roosevelt’s actions, especially in regards to the Grand Canyon of Arizona, set important precedents for his successors, especially President Bill Clinton.
