About this map

Twentymile Waterhole sits at the heart of this Schleicher County landscape, marking a vital water source in an area defined by deep drainage basins and limestone plateaus. The terrain is characterized by the convergence of several major topographic features, including the winding course of N Valley Prong and the broad depressions of North Valley, Live Oak Hollow, and Lake Hollow. These natural landmarks provide essential orientation in a region where human development is primarily limited to a grid of rural ranch roads, such as Co Rd 220 and Co Rd 224. The map illustrates the persistent importance of local water features and named hollows for land management and navigation across the Edwards Plateau in the early twenty-first century.
