History

Hardin County was formed in 1839 from Shelby County, Ohio. In the 1790s and early 1800s, the Hardin County area, especially Cave-In-Rock, was notorious as a stronghold used by outlaws, bandits, river pirates, and counterfeiters.

Geography

According to the U.S. Census Bureau, the county has a total area of 182 square miles (470 km2), of which 178 square miles (460 km2) is land and 4.1 square miles (11 km2) (2.2%) is water.[3] It is the second-smallest county in Illinois by area.

Hicks Dome () is an interesting geological feature in Hardin County. Some believe the dome may be related to an ancient meteor or comet impact, part of the 38th parallel structures, which are a string of geological features running west to Kansas. This is thought to be a string of impact craters from a celestial body that broke apart before striking the earth. However, the Hicks Dome is underlain by ultramafic igneous rocks and igneous diatremes or breccia pipes. Most geologists now accept the theory that the older rocks at the center of the uplift are a result of this deep seated igneous activity. This activity may also have provided the fluorine in the fluorspar deposits in the region. Fluorspar, or calcium fluoride, was mined in Hardin County until the early 1990s.
