The Rio Grande serves as the focal point for this survey along the border between Texas and Tamaulipas, capturing a landscape defined by family ranches and river crossings. Originally surveyed by the Corps of Engineers, U.S. Army in the late 1920s and revised through 1942, the map shows the strategic and agricultural importance of the region near Roma. Notable for its record of early 20th-century life, the sheet identifies numerous family properties like Minitas Ranch and Salinas Ranch, alongside remnants of earlier eras such as the Old Army Camp and the Casa Blanca (ruins). Movement across the international boundary is marked by historic river access points, including the Los Arrieros Ford and El Fronton Ford, highlighting a time when the river was a more permeable border for local commerce and ranching.
