USGS Topo · Published 1967About this map
The Rio Grande snakes along the southern border of this mid-century survey, defining the international boundary between the United States and Mexico. The landscape is dominated by a complex network of water management, featuring the Main Floodway, North Floodway, and the massive Mercedes District Settling Basin. Evidence of the river's historical shifting path is visible in numerous named bancos, including Rosario Banco No 31 and Santa Margarita Banco No 30, alongside the significant Horcon Tract.
