About this map

Agricultural development and international boundaries define this 1930s landscape along the winding Rio Grande southeast of Brownsville. Large landholdings like the Rabb Plantation, Brulay Plantation, and Piper Plantation occupy the fertile river bends, while smaller rural nodes like Southmost and South Point appear near the terminus of the Missouri Pacific railroad. The geography is characterized by several distinctive river-bend land formations, including Los Borregos Banco No 73 and Longoreno Banco No 3, which underscore the shifting nature of the United States-Mexico border in this period.

Local education and infrastructure are represented by the Palm Grove Sch and a prominent Pumping Sta near the riverbank, indicating the era's reliance on irrigation for the valley's plantations. A grid of named thoroughfares such as Indiana Ave, Dakota Ave, and Browne Rd extends northward from the Brownsville Road, showing the early 20th-century partitioning of the South Texas brushland for commercial citrus and produce farming.
