Sassen, Kenneth: - Since viewing his first Native-American rock art near Moab in 1980, Kenneth Sassen has been drawn to photographically document hundreds of sites throughout Desert Western America, especially in Utah. The Moab area is of major importance, for here have been several historic and prehistoric cultures that left their marks over time on the canyon walls. He is a retired atmospheric scientist who now resides in Moab, where, as an avid hiker, he continues to explore many remote places where rock art may reside. In this book, all known significant rock art sites within a 50-mile radius of Moab are discussed and illustrated.
