A popular Ohio River regional recreation area on the peninsula at the confluence of Fourteen Mile Creek and the Ohio River near here was known from the 1880s as Fern Grove. David Rose expanded its facilities in 1923, including an amusement park and a swimming pool, and named it Rose Island. Major access was by car to a swinging foot bridge over the creek and by steamboats on the river. It closed after extensive damage from the 1937 flood. The area known as Fern Grove-Rose Island became part of the Indiana Army Ammunition Plant circa 1940 and was later included in Charlestown State Park, established in 1993. The rugged and scenic area is rich in geological features, archaeological remnants, and habitat for wildlife.
