Very attractive and colorful large-scale folding map of the forested areas in eastern Oklahoma. The map has vivid lithographic printing and shows much detail including towns, railroads, watershed, topography and early surveying. This example is from the U.S. Geological Survey's Twenty-first Annual Report, Part V. Pl. CXLII, and was compiled by Gilbert Thompson, F.E. Mathes and M.L. Cudlip under the direction of C.H. Fitch.
