Rio Grand Valley: America's Almost-as-Grand Canyon

(From Andreas F. Borchert, via Wikimedia Commons, used without permission)

That's the Rio Grande Valley: Not quite as big as the Grand Canyon, nowhere near as well known, and spectacular in its own right.

Google has assembled a decent timeline for the Rio Grande Valley's history, from 1540 to 2007.

There's quite a bit of information about the Rio Grande River at "RIO GRANDE." (The Handbook of Texas Online)

To read some resources, the Rio Grande is a Texas river. For most of its length, it's the boundary between Texas and Chihuahua, Coahuila, Nuevo León (for nine miles), and Tamaulipas, but it starts in Colorado and runs through New Mexico on its way to the Gulf of Mexico.

Going past Albuquerque, New Mexico.
