About this map

The Rio Grande meanders along the international boundary between the United States and Mexico in this early 20th-century survey of Hidalgo County. The landscape is defined by the complex hydrology of ancient river channels, including Resaca Sardinas and Resaca La Cruz, which snake through the alluvial plains south of the growing rail corridor. Settlement patterns follow the St Louis Brownsville and Mexico railroad, which anchors the towns of Mc Allen, Pharr, San Juan, and Donna.

Agricultural development is evident at the Valley View Plantation and the small station at Ebenezer. The historic Military Road parallels the river, providing a terrestrial link between the interior and the borderlands. This map captures the region at a pivotal moment when the irrigation and rail infrastructure began transforming the chaparral into a structured agricultural grid, while the unpredictable loops of the Rio Grande still dictated the natural geography of the valley.
