The Koy Ranch and Hendrick Ranch define the settlement pattern of this West Texas ranching landscape, which was updated by the U.S. Geological Survey through 1979 aerial photography. The terrain is characterized by a series of drainages, most notably Live Oak Hollow and North Valley, which converge as they move through the quadrangle. A significant local landmark, the Twentymile Waterhole, serves as a critical water source in an area otherwise marked by ephemeral features and scattered Gravel Pits.
