Nature
Sinnemahoning State Park in north-central Pennsylvania preserves a mountainous landscape of steep valleys, streams, wooded ridges, and abundant wildlife, including elk and bald eagles. People lived here 10,000 to 12,000 years ago, and archaeological evidence survives in the creek bottomlands. The area, whose name comes from an American Indian term meaning “Rocky Lick,” remained largely wild until 19th-century logging stripped the old-growth forest, triggered wildfires, and damaged streams and wildlife. The modern park grew from flood-control efforts: the George B. Stevenson Reservoir was built in 1955, the park opened in 1958, and it became a state park in 1962.
