Keystone Ranch and its surrounding pastoral landscape define this corner of Frio County, where a network of water sources and rural roads supports a specialized ranching economy. The drainage patterns of San Miguel Creek, Black Creek, and Cat Creek organize the terrain, eventually feeding into southern reaches like Huckberry Creek and Live Oak Creek. A notable reliance on groundwater is evident through the naming of several specific sites, including Creek Windmill, Loston Windmill, and Triangle Windmill. These features, along with Howard Lake, provide insight into the infrastructure required for land management in this Texas environment. The road system is dominated by both established farm-to-market routes and local thoroughfares such as Malone Rd and Keystone Rd, which connect the scattered ranching operations across the brushland.
