A topographic map at a scale of 1:250,000 of the Moab quadrangle and similar maps at a scale of 1:62,500 for the Thompson, Cisco, Moab, and Castle Valley quadrangles are available from the U.S. Geological Survey, Denver Distribution Section, Federal Center, Denver, Colo. 80225, from the Canyonlands Natural History Association at Moab, and from privately owned shops where maps are sold. Most of the park is covered by the Thompson and Moab quadrangles. The southern part of the park is shown also on the Moab 4 NW, Moab 4 NE, and Mt. Waas 3 NW quadrangles at a scale of 1:24,000. A special topographic map of Arches National Park at a scale of 1:50,000 is in preparation by the U.S. Geological Survey. These maps also may be obtained from the above-listed sources.
