The geological history of Clark County is described ranging from 500 million years ago to the present. One-third of present-day Clark County is in the Ouachita Mountains, two-thirds is in the Coastal Plain. The formation of the Ouachita Mountains is described, as is the cretaceous formations that led to biological fossils. Historic mining of minerals is also discussed. For the more technically inclined, a detailed description of the geological formations of the county is included near the end.
