The papers of David Lewis span the years 1879-1984, with the bulk of the material covering the years 1907 to 1935. Included are correspondence, photographs and newspaper clippings, some about Lewis, others about things of interest to him. Two relics of the Sheepeater Campaign, a fork and the shoe of a mule, were returned to the Taylor Ranch in December 1991. Material relating to the use of the Taylor Ranch by the University of Idaho College of Forestry is found in the papers of President Ernest Hartung (UG 13).
