Buffalo River is one of the few remaining free-flowing rivers in the lower 48 states, encompassing 150 miles from the Boston Mountains to the White River. The park contains approximately 95,730 acres of 857,607 acres in the Buffalo River watershed. The park is located in the Salem Plateau of the Ozark Highlands in northern Arkansas. Sections of BUFF lie within the Boston Mountains with elevations up to 2000 feet. Steep-sided valleys and high ridges characterize the topography. The karst landforms of the region feature a large number of sinkholes, springs, and seeps that formed in the limestone and dolomite. The park has the largest cave system in the state of Arkansas. Conduits of rock create complex water flow, where surface water can affect ground water through quick recharge.
