2019 Map of San Pedro Hill

About this map

The Rio Grande forms the definitive southwestern boundary of this Webb County landscape, marking the international border between the United States and Mexico. This section of the river valley is characterized by the winding path of Carricitos Cr, which drains the upland terrain toward the primary river system. The map reveals a sparsely settled ranching or resource-based environment, where water access is a critical geographic marker. Notable for its specific location and naming, Johnson Waterhole Number One indicates the historical importance of managed water points in this arid region of South Texas. The network of secondary roads and local routes, including the prominent Mines Rd, suggests an infrastructure built to support the transit of goods or livestock between the riverfront and the interior highlands.
