High Quality Content by WIKIPEDIA articles! Quehanna Wild Area is a wildlife area within parts of Cameron, Clearfield, and Elk counties in the U.S. state of Pennsylvania; with a total area of 48,186 acres (75 sq mi; 195 km2), it covers parts of Elk and Moshannon State Forests. Founded in the 1950s as a nuclear research center, Quehanna has a conflicting legacy of radioactive and toxic waste contamination, while also being the largest state forest wild area in Pennsylvania, with herds of native elk. The wild area is bisected by Pennsylvania Route 1011, the Quehanna Highway, and is home to second growth forest with mixed hardwoods and evergreens. Quehanna has two state forest natural areas: the 1,215-acre (492 ha) Wykoff Run Natural Area, and the 917-acre (371 ha) Marion Brooks Natural Area. The latter has the largest stand of white birch in Pennsylvania and the eastern United States.
