Missouri, United States
Taum Sauk Mountain in the Saint Francois Mountains is the highest point in the U.S. state of Missouri, 1,772 feet (540 m) above mean sea level.
The topography of Taum Sauk is that of a somewhat flat ridge rather than a peak.

, Taum Sauk and the St. Francois range are true mountains, being the result of a volcanic orogeny. Whereas vertical relief in the rest of the Ozarks region is the result of erosion of sedimentary strata, the St. Francois are an ancient Precambrian igneous uplift several times older than the Appalachians. Geologists believe that Taum Sauk and its neighbors may be among the few areas in the US never to have been submerged in ancient seas.
