L. 59--209, 34 Stat. 225, 54 U.S.C. § § 320301--320303), is an act passed by the United States Congress and signed into law by Theodore Roosevelt on June 8, 1906 . This law gives the President of the United States the authority to, by presidential proclamation, create national monuments from federal lands to protect significant natural, cultural, or scientific features . The Act has been used more than a hundred times since its passage . </P> <P> The Antiquities Act was signed into place by President Theodore Roosevelt during his second term in office . The act resulted from concerns about protecting mostly prehistoric Native American ruins and artifacts--collectively termed "antiquities"--on federal lands in the West, such as at Chaco Canyon, New Mexico . Removal of artifacts from these lands by private collectors, "pot hunters," had become a serious problem by the end of the 19th century . In 1902, Iowa Congressman John F. Lacey, who chaired the House Committee on the Public Lands, traveled to the Southwest with the rising anthropologist Edgar Lee Hewett, to see for himself the extent of the pot hunters' impact . His findings, supported by an exhaustive report by Hewett to Congress detailing the archaeological resources of the region, provided the necessary impetus for the passage of the legislation . </P>
