The Ozarks, also known as the Ozark Mountains, Ozark Highlands or Ozark Plateau, is a physiographic region in the U.S. states of Missouri, Arkansas, Oklahoma and the extreme southeastern corner of Kansas. The Ozarks cover a significant portion of northern Arkansas and most of the southern half of Missouri, extending from Interstate 40 in central Arkansas to Interstate 70 in central Missouri.
The Buffalo River, located in Northern Arkansas, was the first National River to be designated in the United States. The Buffalo River is 153 miles (246 km) long. The lower 135 miles (217 km) flow within the boundaries of an area managed by the National Park Service, where the stream is designated the Buffalo National River. The river flows through Newton, Searcy, Marion, and Baxter Counties, from west to east. The river originates in the highest part of the Boston Mountains of the Ozarks, flows out onto the Springfield Plateau near the historic community of Erbie, and finally crosses a portion of the Salem Plateau just before joining the White River. The Park is home to the state's only elk herd. The upper section of the river in the Ozark National Forest is managed by the U.S. Forest Service and is designated as a National Scenic River and a National Wild River; that section is not part of the area managed as a park by the Park Service but is managed as a part of the Ozark National Forest.
