The 1-430 bypass around the west end of Little Rock, Arkansas, offers a unique section of Paleozoic age rocks demonstrating the various facies and structural styles in the eastern Ouachita Mountains (Stone and McFarland, 198 1). The sections are easy to reach; just drive to Little Rock, Arkansas, on the interstate system and follow the signs to 1-430. The site descriptions are arranged from north to south, starting about 0.8 mi (1.3 km) south of the 1-430 bridge over the Arkansas River.
