Miller County's location made it the “Gateway to the Southwestern United States” via its rivers, stagecoach roads, and Native American trails.

Fouke (which is located in the county) is a small town in southwest Arkansas that is best known as being the locale for the Fouke monster legend- one of the most popular legends in the state. The town attracted attention in the early 1970s when a resident of Texarkana reported seeing a mysterious creature there. A reporter for the Texarkana Gazette wrote an article about it and a legend was born. Fouke and its monster became famous and were featured in the 1973 movie The Legend of Boggy Creek. The Fouke monster has been described as something of a Southern Sasquatch- a “big-foot-type monster.” The documentary style film on the creature was made by South Arkansas native Charles Pierce in the early 1970s. The film assured a place in folklore history for the Bigfoot look-a-like, which has allegedly been seen in and around Fouke since the 1940s. The low budget, campy movie earned cult status and the familiarity of this tale and the regular resurgence in the media of yeti, Bigfoot, and caveman-like characters keep the legend alive.
