In the 1920s, nationwide attention focused on South Arkansas when the Smackover Field[2] was ranked first among the nation's oil fields. For five months in 1925, the 40-square-mile (100 km2) 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.[3]
