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.

 

[5]This is numbered stop 1 in the booklet referred to earlier “The Guide

to an Auto Tour of Arches National Park,” and corresponds to the

numeral one on a small sign at the roadside parking place. Some of

the other numbers are given in the pages that follow.
