About this map

The Rio Grande carves a dramatic international boundary through this portion of Webb Co just before the Second World War. This territory, documented by the Corps of Engineers, is defined by its arid landscape and essential water sources, centered on the Chupadera Ranch. The map reveals a land managed through dispersed water points and natural springs, such as Chupadera Spring and Sullivan Spring, which were critical to ranching operations in this border region.

Physical landmarks like Cathedral Rock provide orientation across the undulating terrain north of the river. The presence of Loza Tank and various drainages like Chupadera Cr and San Ambrosia Cr illustrate how early twentieth-century inhabitants utilized the seasonal hydrology of the brush country. This survey captures the rural infrastructure of the Texas-Mexico borderlands during an era of significant military mapping for civil use.
