The Ouachita Mountains (/ˈwɒʃɪtɔː/), simply referred to as the Ouachitas, are a mountain range in western Arkansas and southeastern Oklahoma. They are formed by a thick succession of highly deformed Paleozoic strata constituting the Ouachita Fold and Thrust Belt, one of the important orogenic belts of North America.[3] The Ouachitas continue in the subsurface to the northeast, where they make a poorly understood connection with the Appalachians and to the southwest, where they join with the Marathon uplift area of West Texas.[3] Together with the Ozark Plateaus, the Ouachitas form the U.S. Interior Highlands.[4] The highest natural point is Mount Magazine at 2,753 feet (839 m).[2][5]
The Ouachita Mountains is a Level III ecoregion designated by the Environmental Protection Agency (EPA). The region has been subdivided into six Level IV ecoregions.[6][7]
