When Red River Valley is referred to, are they talking Texas or Oklahoma or both?

It's always been my understanding that the term "Red River Valley" refers to the areas both north and south of the Red River.

If you'll do a little research, you'll find that the Red River valley is first noted in the history books as being near the Canadian border.

The Red River Valley of the Texas - Oklahoma region is much more famous than the Red River Valley of Canada. The Red River Valley of the Southwest was first settled in the 1830s. And I was not referring to the song, which probably has Texas origins. My question was to what geographical boundries the valley extended. Thank you.

Only in time period and westward expansion.

When you talk of the Red River Valley, you're talking about the immediate valley surrounding, that is, both sides of the river.

Didn't think this would be a big issue... The common meaning for a river valley is the alluvial flood plain generally bounded by a terrace or ridge on each side of the stream above which flood waters do not normally extend. Anything in between is considered a part of the river "valley."

It is always good to get a scientific explanation for questions of the mind. It tends to reinforce our rational thoughts and do away with the irrational.

The Red River valley as I know it extends into the Texas panhandle making up what is now called "Palo Duro" canyon.My ancestors reffered to it as Numu Soko....Comanche Land...it was a stronghold for our people for many,many generations.Th Red River valley between Texas and Okla. was known as Eka Okwetu.....meaning Red River,not because of its amounts of red clay but because of the habit of Whee-Chee-Tah {Whicita}Indians of burying their dead in the banks of the river.The idea that it was settled in the 1830s is quite unfair.Agricutural tribes such as the Whicitas,Caddoes and also the buffalo hunting tribes such as Comanche and Apache had been ther for centuries.Please include all the people who make up the history of an area.

Saying the Red River Valley was settled in the 1830s was an oversight on my part. The inference was to the settlement of Europeans in that particular area. I am well aware that Native Americans were in the area many years in advance. Thank you for informing us that it was known as Numu Soko by the Comanche.
