context_page_description: Randolph County is located between the Ozark Mountains and Arkansas Delta in the U.S. state of Arkansas. The county is named for John Randolph, a U.S. senator from Virginia influential in obtaining congressional approval of the Louisiana Purchase, which includes today's Randolph County. Created as Arkansas's 32nd county on October 29, 1835, Randolph County has two incorporated cities, including Pocahontas, the county seat and most populous city. The county is also the site of numerous unincorporated communities and ghost towns.
  Crossed by five rivers, most of Randolph County contains foothills and valleys typical of the Ozarks. However, the eastern side of the county is largely flat with fertile soils typical of the Delta, with the Black River roughly dividing the regions. The county contains three protected areas: two Wildlife Management Areas and Davidsonville Historic State Park, which preserves and interprets an early pioneer settlement. Other historical features such as log cabins, one-room school houses, community centers, and museums describe the history and culture of Randolph County.
context_section_description: Water is an extremely important part of Randolph County's geography, history, economy, and culture. The many rivers, streams, and ditches crossing the county have featured prominently since prehistoric times, and many of the hundreds of archaeological sites are along waterways. Tribes of Lenape, Shawnee,  and Cherokee were settled in the area along rivers but left the area following the 1811–12 New Madrid earthquakes.
  Randolph County is home to five major rivers: Black River, Current River, Eleven Point River, Fourche River, and Spring River.
  Running from east to west toward its own mouth in the southern tip of Randolph County, the Black receives the Current River and Fourche River east of Pocahontas. The Current River serves as the northeastern county boundary with Clay County before turning southwest, passing Reyno and Biggers and meeting the Black east of Pocahontas. The Fourche River enters Randolph County near Doniphan, Missouri and runs south to meet the Black east of Pocahontas. The Black meets the Spring at the southern tip of Randolph County near Black Rock.
  The Spring River serves as the county's southwestern boundary with Lawrence County between Davidsonville Historic State Park and Ravenden. The Eleven Point River enters from Missouri near Billmore and runs south to empty into the Spring just west of the state park.
  Rivers brought early prosperity to the county during white settlement for navigation. Control of the rivers and Pitman's Ferry led to military action in the county during the Civil War, including a skirmish in 1862. Following the war, natural mineral springs purported to have healing properties attracted visitors to Warm Springs and Ravenden Springs.
