Keystone State Park was established in 1945. After 1839, accounts of the Bear Cave began to appear in local newspapers. Some 8,500 feet of passages have been mapped and it has become a popular recreational site. The Bear Cave is a natural maze of caverns. Other dangers that early settlers faced included bears, panthers, and foxes. To protect the citizens of Derry township from Indian attacks, Fort Barr and Fort Wallace were built in 1774. Later, her father and two of her brothers, along with William Guthrie and Richard Wallace and others migrated to Derry township. When they returned, each brought with him a wife. One winter, a few years after settling in Derry township, Pomroy and Wilson returned to their homes in the East. Later, James Wilson came and settled near by and they helped one another build and farm. After hearing of the land being settled by soldiers from Forbes' army, John Pomroy, a man of Scots-Irish descent, left his home in Cumberland valley and settled in Derry township, near present-day New Derry. The first settlements in Derry township were created by soldiers from Forbes' army in 1762.
