The Cummings-Douglass Expedition
Rainbow Bridge was undoubtedly known to local Indian tribes of the area, both prehistoric and historic. There is also evidence to support the likelihood that a few cowboys and prospectors had also stumbled across the span in the course of their wanderings. Yet, it was not until 1909 that Rainbow Bridge was "discovered" and publicized to the outside world. That discovery was shared by two veteran Southwestern scholars--Dr. Byron Cummings and William B. Douglass--who were united, albeit briefly, by John Wetherill, a famous Southwestern trader and explorer in his own right.
