Heavener Runestone Park is a 55-acre (220,000 m2) park located in Le Flore County, Oklahoma. It is located near the city of Heavener, Oklahoma. Formerly a state park of Oklahoma, it was transferred to the City of Heavener in 2011, and is now operated by the Friends of Heavener Runestone, a non-profit organization. The Festival held at the park on two weekends a year serves as a fundraiser for operating and maintaining the park.
Opened in 1970, the park has been erected around the Heavener Runestone, a runestone found in 1923, and most likely inscribed in the 19th century, perhaps by a Swedish immigrant. The stone is located on Poteau Mountain just outside the town's limits. (Wikipedia)
