1955 Map of Los Fresnos

About this map

Palo Alto Battlefield dominates the southern landscape of this Cameron County survey, preserving the site of the first major engagement of the Mexican-American War. A Historical Monument marks the location amidst a complex network of hydraulic engineering, including an extensive aqueduct, numerous ditches, and a levee system designed to manage the Rio Grande delta’s variable water levels. The settlement of Los Fresnos serves as the central hub, supported by the Southern Pacific railroad and a grid of rural routes such as Henderson Road and Old Point Isabel Road. The map reveals a land defined by its resacas—former river channels—including the winding Resaca de los Cuates and Resaca de los Antonias. Smaller rural communities and named locales like Agua Negra, Charco Hondo, and Bayview illustrate the agricultural settlement patterns of the mid-20th century.
