Johnson Canyon - Virtual EDventures    NEW!

When the Santa Fe Railroad was constructing their line across northern Arizona in the early 1880s, they overcame many physical obstacles in the rugged landscapes they traversed. One of the more difficult was the steep drop westwards off the Coconino Plateau, between Williams and Ash Fork. Their surveyors and engineers chose a somewhat obscure canyon as the optimum route off the plateau, a canyon so rugged that it required the only tunnel from Albuquerque to Los Angeles. We will explore this canyon, visiting many man-made features related to the construction and operation of the railroad, including the now-abandoned Johnson Canyon Tunnel and the only functional dam of steel construction in the United States. Our explorations will also include some strange and interesting natural features, and we will hear the story of rancher and homesteader George Johnson, after whom the canyon is named. The video link will be emailed upon registration.
