About this map

The Caprock Escarpment creates a sharp divide on this late 1960s survey of the High Plains, where the flat western tableland drops abruptly into the intricate drainage systems of Briscoe and Floyd Counties. The terrain is defined by deeply incised features like Pole Canyon and Dark Canyon, which channel seasonal runoff toward the eastern lowlands. This transition zone is marked by numerous water sources critical to ranching and local history, including Lingos Falls and the isolated Red Rock Spring.

While the western portion of the sheet is sparsely populated with scattered wells and cattle fences, the canyons provide more complex landscape features such as Grahams Lake and Cottonwood Lake. The map details the winding course of Los Lingos Creek as it carves through the breaks, offering a technical look at the hydrology of the area before modern land-use changes. Named landmarks like Hackberry Creek and Gay Hollow provide specific points of reference for genealogists and local historians tracing family holdings along the county line.
