The Buffalo National River, located in northwestern Arkansas, was designated as our first National River in 1972. Today the river runs free for 135 miles as the centerpiece of approximately 95,000 acres of Ozark wilderness designated as a national park. The river shares the park with Rocky Mountain elk, introduced in the 1980s, black bear and white tailed deer. This area has been inhabited for some 10,000 years; the Tyler Bend Visitors Center includes exhibits on Native American people as well as later pioneer homesteads and the Boxley Grist Mill.
