About this map

Keystone Ranch serves as the central hub of this South Texas landscape, situated amongst the scrub and undulating terrain of Frio County. The map reveals an environment defined by water management in a semi-arid region, evidenced by numerous named wells and windmills such as Creek Windmill, Loston Windmill, and Triangle Windmill. These features indicate the vital importance of groundwater for cattle ranching and local operations during the late 1960s.

The eastern portion of the sheet is dominated by the drainage of San Miguel Creek and the notable Marshall Hills, while Keystone Road provides the primary transit artery through the ranching country. Industrial activity is represented by scattered Gravel Pits and a Borrow Pit, suggesting localized resource extraction. The presence of Howard Lake and several seasonal creeks like Black Creek and Hackberry Creek further illustrate the hydrology of this rural Texas ranchland.
