The Heavener Runestone is a large stone slab located in Heavener, Oklahoma. It features inscriptions in the Elder Futhark runic alphabet, which is associated with the ancient Germanic peoples. The stone is believed to date back to the 11th century, although its exact origins and meaning remain subjects of debate among historians and archaeologists. Discovered in the 1830s, the Heavener Runestone has drawn interest for its potential connections to Norse exploration in North America. Some researchers suggest it may indicate that Vikings reached this area long before Columbus. The site is now a part of the Heavener Runestone Park, attracting visitors and scholars alike.
