Geology

Rising topographically from the Great Plains in eastern Wyoming and western South Dakota, the Black Hills are conspicuous on the map by the outcrop of Precambrian rock. The upturned and eroded Paleozoic and Mesozoic strata of this structural dome surround the ancient granite on which the four faces of the Mt. Rushmore presidential monument were carved. Geologically, the Black Hills represent the easternmost outpost of the Rocky Mountains. - USGS
