U.S. #1084 commemorates the 50th anniversary of the Antiquities Act of 1906, a federal law that provided for America’s natural wonders. In 1906, President Theodore Roosevelt designated Devils Tower National Monument as the first such protected area. Devils Tower has an altitude of 5,112 feet above sea level, and rises over 1,200 feet over the surrounding area. Numerous Native American tribes consider it a sacred landmark.
