South Arkansas lies within the southernmost portions of Arkansas Gulf Coastal Plain and Arkansas Delta regions.
History
In the 1920s, nationwide attention focused on South Arkansas when the Smackover Field
was ranked first among the nation's oil fields. For five months in 1925, the Smackover Field was the focal point of one of the wildest mineral booms in North America. Today, south Arkansas's oil fields produce petroleum throughout a 10-county area.
Columbia and Union counties also stretch over one of the largest brine reserves in the world. Bromine is derived from brine, or saltwater, and local companies play an international role in the commercialization of bromine and its many applications.
