The Joel E. Fletcher Photograph Collection consists of images of experiments and equipment from the United States Department of Agriculture. Most of the photos are from Arizona including Graham Mountains, Black Canyon, Gila, Tuscon, and Safford, as well as 23 aerial views of Page Ranch. These images appear to have been taken by Darwin Anderson.

This collection consists of fifty stereoscopic cards taken by photographers Timothy H. O'Sullivan and William W. Bell between 1871 and 1874 during the Army Corps of Engineers geographical survey led by Lieutenant George Montague Wheeler. The views in this collection consist of geological formations (including some of the first images of the Grand Canyon); members of the Zuni, Mojave, Navajo, Apache, and Ute tribes; scenic views; and ancient puebloan ruins.
