To provide land survey information for users working in the upper Washita River basin. Geological Survey Digital Line Graph (DLG) data sets based on 100,000-scale topographic quadrangles. This data set was created by appending and editing U.S. This spatial layer contains township, range, and section boundaries from the public land survey system for the upper Washita River basin in southwestern Oklahoma.

The vertical lines of the PLSS grid are called range lines, and the horizontals are called township lines. PLSS markings carved into a tree in the Beaverhead Mountains.
