Keystone State Park

Keystone State ParkKeystone State Park was named as an homage to the Keystone Coal and Coke Company and the coal mining heritage that has contributed to the culture of the Derry Area and much of Western Pennsylvania. The Keystone Coal and Coke Company built the Keystone Dam in 1909, creating a 78 acre lake. When the demand for coal and coke declined in the late 1930’s and early 1940’s, many coal companies began looking to sell off their land. In 1945, the Keystone Coal and Coke Company sold this portion of land to the state of Pennsylvania and it was incorporated into the Pennsylvania State Parks system. Today Keystone State Park consists of 1,200 acres with Keystone Lake as the backdrop and a wide variety of recreational opportunities offered throughout the year. Click pictures to enlarge.
