A rural Ozarks scene. Phelps County, Missouri The Saint Francois Mountains, viewed here from Knob Lick Mountain, are the exposed geologic core of the Ozarks.. The Ozarks, also known as the Ozark Mountains, Ozark Highlands or Ozark Plateau, is a physiographic region in the U.S. states of Missouri, Arkansas, and Oklahoma, as well as a small area in the southeastern corner of Kansas.

Originally known as the Oklahoma Bat Caves National Wildlife Refuge, Ozark Plateau National Wildlife Refuge was established for the protection of endangered bats and their habitat. The refuge is made up of several parcels of land located in northeastern Oklahoma. These parcels contain numerous caves considered crucial for the bats' survival.
The Springfield Plateau is the only Ozark Highland Level IV ecoregion within all four states. [1] The nearly level to rolling Springfield Plateau is underlain by cherty limestone of the Mississippian Boone Formation and Burlington Limestone; it is less rugged and wooded than Ecoregions 38, 39b, and 39c, and lacks the Ordovician dolomite and limestone of Ecoregions 39c and 39d.
the Missouri portion of the Ozark Plateau (areas 14a and 14b) which lies between the Mississippi Alluvial Plain and the Central lowland. The boundary between the northern plains and the Ozark region follows the Missouri River from its mouth at St. Louis to Columbia.
The Saint Francois Mountains were formed by igneous activity, whereas most of the surrounding Ozarks are developed on Paleozoic sedimentary rocks as a dissected plateau. The localized vertical relief was caused by erosion following uplift during the Pennsylvanian and Permian periods produced by the Ouachita orogeny to the south.
This is a list of natural springs in the Ozark Plateau ordered by spring magnitude.Different sources may give differing values for average daily flow of the same spring. This can result from different measuring methodologies and from a varying number of observations over different timesp
Mammoth Spring is a large, first magnitude karst spring that arises in the Ozark Plateau within the state of Arkansas. It is the largest spring in Arkansas and the third-largest spring within the Ozark Plateau region behind Big Spring and Greer Spring. Mammoth Spring is the seventh-largest natural spring in the world.
Ouachita Orogeny geologic map The Ouachita Mountains lie south of the Arkansas River valley which separates them from the Ozark plateau. The Ouachita orogeny was a mountain-building event that resulted in the folding and faulting of strata currently exposed in the Ouachita Mountains.
