I am grateful to several colleagues and friends for the loan of photographs, for geologic help and data, and for reviewing this report. I am also deeply grateful to my wife, Ruth, for accompanying me on all the fieldwork and for her help and encouragement.

Footnotes

[1]Mrs. Tanner, of Phoenix, Ariz., is the author of an earlier history of Moab (her hometown). She has completed a revision entitled, “The Far Country—A Regional History of Moab and La Sal, Utah,” which will be serialized in the Moab Times-Independent, after which it will be published.

[2]For the benefit of visitors from countries in which the metric system is used, the following conversion factors may be helpful: 1 inch = 2.54 centimeters, 1 foot = 0.305 meter, 1 mile = 1.609 kilometers, 1 U.S. gallon = 0.00379 cubic meter.

[3]Barrier Creek flows through Horseshoe Canyon in the detached unit of Canyonlands National Park. The canyon walls are adorned by striking pictographs ([Lohman, 1974, fig. 2]). “Barrier Canyon style” is named after the pictographs found in Horseshoe Canyon.

[4]Plastic-relief maps are no longer available from the U.S. Army Map Service but may be obtained from the T. N. Hubbard Scientific Co., Box 105, Northbrook, Ill. 60062. 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.
