From the book:
Native American cultures have flourished in the Four Corners region for thousands of years, from the early shamans, to the Anasazi, to historic tribes of today. Rock art images created by these cultures are diverse, mysterious, and haunting. Utah may contain more world-class, prehistoric rock art than any other region in North America. Rock overhangs with ghostly, painted, shamanistic figures have become synonymous with Utah.
Dennis Slifer has done extensive field work to identify those sites suitable for public visitation. Complete with maps and directions, this book describes more than fifty sites with public access in Utah, the Arizona strip, southern Nevada, and the western edge of the Colorado. Richly illustrated with photographs and drawings Guide to Rock Art of the Utah Region is a must for all rock art enthusiasts.
Slifer's other books include Signs of Life: Rock Art of the Upper Rio Grande, and co-author of Kokopelli: Fluteplayer Images in Rock Art.
