(Pennsylvania)
Ryerson Station State Park is a 1,164-acre (471 ha) Pennsylvania state park in Richhill Township, Greene County, Pennsylvania in the United States. It was previously home to Ronald J. Duke Lake, a 52-acre (21 ha) artificial lake on the North Fork of the Dunkard Fork of Wheeling Creek, that was constructed in 1960, but drained in 2005 due to structural concerns about the dam. Ryerson Station State Park is 3 miles (5 km) from Wind Ridge just off Pennsylvania Route 21 very close to the West Virginia state line. (Ref: https://en.wikipedia.org/wiki/Ryerson_Station_State_Park)
