Management -- Caring for Your Park
Many documents guide the management of Arches. Those available here demonstrate how park operations are structured toward achieving the mission of the National Park Service. All require Adobe Acrobat Reader for viewing.
Presidential Proclamation No. 1875 signed by President Herbert Hoover on April 12, 1929, established Arches National Monument for its "gigantic arches, natural bridges, windows, spires, balanced rocks, and other unique wind-worn sandstone formations, the preservation of which is desirable because of their educational and scenic value." Only two small sections of land comprised the new monument: 2,600 acres known as "Devil's Garden" and 1,600 acres called "Windows."
Just under a decade later, a second presidential decree (No. 2312) signed November 25, 1938 by Franklin D. Roosevelt expanded the monument to preserve a contiguous 29,160 acres, "necessary for the proper care, management, and protection of the objects of scientific interest situated on the lands included."
The boundary was again modified by President Dwight Eisenhower (Proclamation No. 3360, signed July 26, 1960) and President Lyndon Johnson (No. 3887, signed January 21, 1969).
Finally, on November 12, 1971, Congress passed Public Law 92-155, signed by President Richard Nixon, creating Arches National Park.
