2013 Map of South of San Pedro Hill

About this map

The Rio Grande serves as the primary geographical anchor for this section of Webb County, defining the international boundary through a series of sweeping bends. In this corner of Texas, the landscape is shaped by the legacy of early twentieth-century industry and transport along the river. The settlement of Santo Tomas is situated in the north, connected to the broader region by Mines Rd, a name reflecting the historical coal and mining activities that once dominated this corridor. Further downstream, the settlement of Minera sits near the riverbanks, marking a site with deep roots in the Laredo-area mining district. This survey provides a clear view of the sparse rural infrastructure of the era, including the Upper Columbia Crossing, illustrating how the proximity to the river influenced local road networks and settlement patterns in this arid borderland.
