History
Allendale County was formed in 1919 from southwestern portions of Barnwell County, along the Savannah River, and part of Hampton County, just to its south. It is the location of the Topper Site, an archeological excavation providing possible evidence of a pre-Clovis culture dating back 50,000 years. The site is near a source of chert on private land in Martin owned by Clariant Corporation, a Swiss chemical company with a plant there. The site, named after John Topper, a local resident who discovered it, has been under excavation by archeologists from the University of South Carolina for about one month a year since 1999, after an initial exploratory dig in the mid-1980s.
