The Webb and Duval county line marks the vertical axis of this South Texas landscape, defined by the dry drainage patterns of the Brush Country. The ephemeral Arroyo de Charco Escondido meanders across the central terrain, providing a critical geographic marker for land tracking in this arid region. Transportation and property access are anchored by the intersection of 59 and Fm 2050, showing the modern connectivity of these sprawling ranchlands. This survey is particularly useful for understanding the relief and natural drainage features of the borderlands where the coastal plains begin to rise into the South Texas interior.
