1955 Map of Southmost

About this map

The Rio Grande creates a deeply meandering border between Texas and Mexico in this mid-century topographic survey of southernmost Cameron County. The landscape is defined by the complex hydrological patterns of the river, where numerous bancos such as La Canasta Banco No 4 and Longoreno Banco No 3 illustrate the shifting nature of the international boundary. An extensive system of Levees and drainage ditches protects the agricultural operations that dominated the local economy during this era, including English Farms and the Brulay Plantation. Cultural landmarks like the Southmost Cem and several family-named ranches, such as Nogales Ranch and Southmost Ranch, anchor the rural community. The presence of the Abandoned Southmost Road indicates a shifting infrastructure as older riverfront routes gave way to newer developments like Browne Highway.
