Rainbow Bridge is one of the world’s largest known natural bridges. The span has undoubtedly inspired people throughout time–from the neighboring American Indian tribes who consider Rainbow Bridge sacred, to the 85,000 people from around the world who visit it each year. 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.
