Jennings Environmental Education Center - Jennings Environmental Education Center is one of several state parks specifically dedicated to provide environmental education and interpretation to the community. A variety of programs are available for children, teachers, and the general public that increase knowledge and awareness of the beauty and importance of our natural resources. By taking some time to explore Jennings through its trail network or community programs, visitors can enjoy the outdoors while learning the skills needed to be good stewards of Pennsylvania's outstanding natural resources.
Jennings provides a unique combination of prairie and forest, which offers a wide array of resource and education opportunities. One of the park's main features, the 20-acre prairie ecosystem, is home to distinctive prairie plants and the endangered massasauga rattlesnake. The most noteworthy and spectacular prairie flower is the blazing star. Jennings was the first reserve established in Pennsylvania to protect an individual plant species and remains the only public and protected prairie in the Commonwealth.
McConnells Mill - McConnells Mill State Park, in Lawrence County, encompasses 2,546 acres of the spectacular Slippery Rock Creek Gorge. Created by the draining of glacial lakes thousands of years ago, the gorge has steeps sides and the valley floor is littered with huge boulders and is a national natural landmark. Slippery Rock Creek is a Class II to IV river, depending on water level. Spring and fall are the best times for whitewater boating. A gristmill built in the 1800s is open for tours. McConnells Mill State Park is open from sunrise to sunset, year-round.
Davis Cabin - Construction began before the American Revolution on this cabin of hand-hewn logs and hand-carved stone. Located behind the Davis Hollow Marina, it was used as a summer home by Mrs. Katherine Davis and her sister Miss Eleanor Holt. A fine example of pioneer construction, there is a safe built within a stonewall, an authentic wagon wheel chandelier and walls made of wormy American chestnut. The building now houses the PA Chapter of the North Country National Scenic Trail headquarters.
Historic Oil Exhibit - An operating central power is tucked in the woods just beyond Muskrat Cove where a stream crosses under the service road. Built at the turn of the century, it contains a Bessemer engine pumping jacks and other equipment used during the early days of the oil industry. The engine is operated several times a year. A book on the Muddy Creek Oil Field is for sale at the park office.
