My deep appreciation goes to Bates Wilson, former superintendent of
Canyonlands National Park, and to Joe Carithers, former assistant
superintendent, for their splendid cooperation in supplying data and
information and for making available four-wheel-drive vehicles. I also
wish to thank Chuck Budge, former chief ranger; Dave May, assistant
chief ranger; Joe Miller, former maintenance engineer; Bob Kerr, new
superintendent; Maxine Newell, park historian and member of the staff at
Arches National Park; Jerry Banta, park ranger at Arches; and Dave
Minor, district ranger for the Needles district, for their many favors.
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
field work and for her help and encouragement.
