Black Moshannon State Park in central Pennsylvania is known for its unusual wetland landscape, centered on Black Moshannon Lake and a large reconstituted bog whose tannin-dark water and northern-style habitat support uncommon plants, animals, and many bird species. Long used by the Seneca, the area was later opened by the Philadelphia–Erie Pike and heavily logged, leaving damaged land after the timber era. From 1933 to 1937, the Civilian Conservation Corps reshaped the area by planting trees, building roads and facilities, and constructing the lake dam, leading to the park’s opening in 1937. Today it combines conservation with year-round recreation.
