Arkansas has few mining ghost towns and many lost river towns. The Mississippi washed away Napoleon, the Desha County seat until 1874, and erosion took the waterfront of Arkansas Post, the first capital of Arkansas Territory. Hopefield, the ferry landing across from Memphis, was burned in the Civil War, rebuilt, and then worn down by yellow fever and the river. Other towns died when the roads went elsewhere: Davidsonville, home of the territory's first post office, was bypassed by the Southwest Trail and nearly empty by statehood in 1836, and Chalk Bluff's people moved to the railroad town of St. Francis.
In the Ozarks, zinc built Rush, which boomed during World War I and lost its last mine in 1931. A sawmill built Graysonia on the Antoine River, and Coin Harvey's resort at Monte Ne now lies mostly under Beaver Lake. Other reservoirs drowned more: Wikipedia's list puts Dubuque and Kingdon Springs under Bull Shoals Lake and Crossroads under Lake Maumelle. Sneed, a farm community in Jackson County, was almost completely destroyed by the state's only documented F5 tornado on April 10, 1929.
What survives is thin. Rush keeps a general store, a smelter and a row of houses inside Buffalo National River. At Davidsonville, Arkansas Post, Chalk Bluff and Cadron, parks with trails and markers stand on the townsites. For most other sites in our index we have not verified what is left.
