Bell made this photograph while he was working on Lieutenant George Wheeler’s Geographical Explorations and Surveys west of the hundredth meridian. He had resigned his post as head of the photographic department in Washington, D.C.’s Army Medical Museum in 1872 to become Wheeler’s official photographer. |
