Ephemeral watercourses define the landscape of this Webb County ranchland, where Santa Isabel Cr and Tierra Blanca Cr wind through the arid terrain. The map highlights a network of private ranch roads, such as Ranch Rd 6236A and Ranch Rd 530A, which serve as the primary infrastructure for these vast agricultural holdings. Smaller tributaries like Cuchara Cr and Chalker Cr etch the surface, illustrating the drainage patterns that dominate the local topography. This 2022 survey documents the contemporary boundaries and access points for the Galvan Ranch area, reflecting a region where land use remains focused on traditional cattle ranching and resource management. The sparse distribution of named features emphasizes the open, rural nature of the South Texas brush country, where transit is restricted to private thoroughfares like Galvan Rd.
