The two highest points in the state are Taum Sauk Mountain at 1,772 ft (540 m) in the St. Francois Mountains in Iron County and Lead Hill just east of the community of Cedar Gap at 1,744 ft (532 m) in the southwestern corner of Wright County. Few localities have an elevation exceeding 1,400 ft (430 m).
Geologic map of the St. Francois Mountain region. The St. Francois Mountains were formed by volcanic and intrusive activity 1.485 billion (1.485 x 10 9) years ago. [6] By comparison, the Appalachians started forming about 460 million years ago, and the Rockies a mere 140 million years ago.
The geology of Missouri includes deep Precambrian basement rocks formed within the last two billion years and overlain by thick sequences of marine sedimentary rocks, interspersed with igneous rocks by periods of volcanic activity. Missouri is a leading producer of lead from minerals formed in Paleozoic dolomite. [1]
Taum Sauk Mountain / ˈ t ɔː m ˈ s ɔː k / [3] in the Saint Francois Mountains is the highest natural point in the U.S. state of Missouri at 1,772 feet (540 m). [4] The topography of Taum Sauk is that of an elongated ridge with a NNW-SSE orientation rather than a peak.
Table Mountain is set in Yellowstone National Park and ranks as the third-highest peak in the park. [2] The mountain is located eight miles (13 km) southeast of Yellowstone Lake, and 2.18 miles (3.51 km) southwest of Eagle Peak which is the nearest higher peak, [5] as well as the park's highest point.
The formal geological name for the Lead Belt is the "Southeastern Missouri Mississippi Valley-type Mineral District". It contains the highest concentration of galena (lead(II) sulfide) in the world [2] as well as significant economic quantities of zinc, copper and silver and currently mined sub-economic quantities of metals such as cadmium, nickel and cobalt.
