1962 Map of San Juan SE

USGS Topo · Published 1965

About this map

Meandering loops of the Rio Grande define the international border in this early 1960s survey of the Lower Rio Grande Valley. The landscape is marked by a unique series of "bancos"—tracts of land created by river shifts—including Monterrey Banco No 89, Longoria Banco No 39, and San Juan del Rio Banco No 40. These features illustrate the complex history of land ownership and boundary adjustments between Texas and Tamaulipas.
