The Ouachita Mountains in southeastern Oklahoma and southwestern Arkansas

The image below as acquired by the newly-operational NOAA 18 satellite shows the Ouachita Mountains in Oklahoma and Arkansas.
Formed from the collision of the North and South American continental plates, this region used to be under the vast ocean that covered the central part of the US.
You can read more about these mountains, and this whole area at the ever-useful Wikipedia: http://en.wikipedia.org/wiki/Ouachita_Mountains
By the way, might the pronunciation of Ouichita sound familiar (when you try to say it)?
