A Mule's Eye View of the Grand Canyon--The Photograph Collection of Trail Guide Ray Tankersley:   Ray Tankersley was a trail guide at the Grand Canyon in the 1920s. It appears that he was there for some time before the Fred Harvey Company acquired the mule franchise in 1927; he stayed until about 1931. Tankersley's photograph collection, donated to the Grand Canyon Archives by McCroskey upon the completion of her book, contains more than four hundred black and white images of the Grand Canyon, mules and mule trails, construction of the 1928 Kaibab Bridge and trails, Phantom Ranch, Hermit Camp, Havasu, the Colorado River, the North Rim, Mary Colter Buildings, and scenes from the Colorado Plateau. The presentation will be a showing of slides of a selection of the photographs. Details in these never-before-seen pictures are of interest to historians and, it is hoped, will be enjoyed for their unusual setting and sheer artistry. Of the millions of photographs taken of the Grand Canyon, relatively few are of mules, with the exception of those taken commercially by the Kolb Brothers at the Bright Angel Trailhead.
