From a Web site: Fifteen Presidents have designated National Monuments. President Bill Clinton designated 19 National Monuments, followed by Theodore Roosevelt with 17, then Jimmy Carter with 15. Presidents Nixon, Reagan, and George H.W. Bush are the only Presidents who have not created National Monuments.
