ABSTRACT
Missouri has within its boundaries more varied natural features than those found in the states that adjoin it, except Kentucky, Tennessee, and Arkansas. The northern part of the state is in the Dissected Till Plains; the western section is in the Osage Cuestas Region; most of the southern part is in the Ozark Upland Region of the Interior Highlands Province; and the southeastern part, including the Bootheel, is the Coastal Plain Province. On the geologic map of Missouri, the Precambrian age granites and rhyolites, shown in a wedge pattern, are found in southern or south-eastern Missouri. Missouri is noted for its large areas of maturely developed karst landscape. Small meteoric material has been found deposited in a linear fashion in a few other locations; thus geologists speculate that the Missouri craters are also the result of meteor impact.
