1940 Map of Chupadera

About this map

The Rio Grande carves a winding international boundary through this portion of Webb Co, where the Texas brush country meets the Mexican state of Coahuila. Based on field work by the Eighth Engineers just before the United States entered World War II, the map reveals a landscape defined by scarce water sources and ranching outposts. Chupadera Ranch sits as a primary center of activity in the interior, supported by nearby Chupadera Spring and the drainage of Chupadera Cr. To the south, isolated water points like Sullivan Spring and Loza Tank provide essential resources in the arid terrain, while Cathedral Rock serves as a prominent natural landmark for those navigating the rugged draws leading toward the river.
