The delta of the Rio Grande is a land shared by two great nations. In Mexico, it is known as el Rio Bravo del Norte. North of the border, it is called the Rio Grande. From Falcon Dam, the river flows toward the Gulf of Mexico through a gradually spreading flood plain or delta. Steamboats once fought the swift current far upriver. In many ways the destiny of North America was forged along its banks. El Valle takes you on a visual journey through the delta, exploring the rich biodiversity and culture that has taken root along its banks.
