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. A gristmill built in the 1800s is open for tours. The park is open from sunrise to sunset, year-round.

McConnells Mill is a featured park, December, in the 2009 Pennsylvania State Parks Calendar.

Whitewater Boating

A river flows between rocks in a gorge at McConnells Mill.

Slippery Rock Creek is a Class II to IV river, depending on water level. Spring and fall are the best times for boating. Boaters generally start from Rose Point (US 422 bridge), outside of the park boundary, and boat to Eckert Bridge, covering 2.5 miles with a portage around the dam at the Old Mill. It is illegal to “run” the dam. Boaters must stay at least 50 feet from the boil at the base of the dam. An additional 3.5 miles of whitewater from Eckert Bridge to Harris Bridge can extend the run for boaters to 6 miles. Rafts, canoes and kayaks are not available for rent in the park.

Non-powered boats must display one of the following: boat registration from any state; launching permit or mooring permit from Pennsylvania State Parks that are available at most state park offices; launch use permit from the Pennsylvania Fish and Boat Commission.

All whitewater boaters on Slippery Rock Creek must learn to recognize natural dangers and understand that injury and death are a possibility when boating Slippery Rock Creek.

Only those properly equipped, trained and experienced should consider whitewater boating. Whitewater boating is permitted in rubber rafts, whitewater canoes and kayaks. Rafts must be at least eight feet long and have at least two air chambers in the gunnels with a minimum outside diameter tube of 14 inches. Non-inflatable canoes and kayaks must be of a design intended for whitewater use. Boating must be in accordance with the American Whitewater Affiliation Safety Code. All boaters enter the water at their own risk. Inner tubes and air mattresses are prohibited.

All boaters must wear U.S. Coast Guard approved personal flotation devices at all times. Helmets are strongly recommended.

International Scale of River Difficulty

The classes below are the American version of the rating system used throughout the world. This system is not exact. Rivers do not always fit easily into one category and there may be regional interpretations. This information is from American Whitewater.

Class I: Easy - Fast moving water with riffles and small waves. Few obstructions, all obvious and easily missed with little training. Self-rescue is easy.

Class II: Novice - Straightforward rapids with wide, clear channels which are evident without scouting. Occasional maneuvering may be required, but rocks and medium-sized waves are easily missed by trained paddlers.

Class III: Intermediate - Rapids with moderate, irregular waves which may be difficult to avoid and which can swamp an open canoe. Complex maneuvers in fast current and good boat control in tight passages or around ledges is often required. Strong eddies and powerful current effects can occur.

Class IV: Advanced - Intense, powerful but predictable rapids requiring precise boat handling in turbulent water. May be large, unavoidable waves and holes or constricted passages demanding fast maneuvers under pressure. Rapids require “must” moves above dangerous hazards. Self-rescue is difficult.

Historical/Environmental Education

A park naturalist is available several days a week on a seasonal basis to conduct guided hikes, night programs and school group activities. Please contact Moraine State Park for more information or to schedule a program.

The operational gristmill shows how waterpower ground grains into flour in the days before modern electricity-powered mills. Guided tours of the mill are available Memorial Day through Labor Day and as otherwise posted.

The Old Mill is open 11 a.m. to 5 p.m. Off-season tours are by appointment only.

Trail of Geology

The natural character of McConnells Mill State Park, the scenic gorge, waterfalls, rugged hiking trails and whitewater creek, are all directly caused by the geology of the area. The bedrock formed over 300 million years ago as layers of sand, mud and peat in what was a coastal area. After becoming rock, these different layers were lifted to the surface in several mountain-building events. The different strengths of these rocks cause them to erode differently, helping to make the varied landscape of the park. The gorge and the dramatic topography of the park were created by glaciers over the past two million years.

To learn more about the geology of the park, pick up a copy of the ‘Trail of Geology’ brochure at the park office, or visit the Web site. This driving tour brochure corresponds to numbered posts throughout the park and surrounding area.

Heritage Festival

People watch a presentation on American Indians at McConnells Mill.

McConnells Mill Heritage Festival is held on the last full weekend in September. The festival celebrates the operational era of the Old Mill (1852-1928).

History of the Old Mill

In 1852, Daniel Kennedy built the first gristmill on Slippery Rock Creek. Fire destroyed the mill so he rebuilt it in 1868. Thomas McConnell bought the mill in 1875, and improved it by replacing the waterwheel with water turbines and the grinding stones with rolling mills. One of the first rolling mills in the country, it processed corn, oats, wheat and buckwheat for local customers. Sagging profits and antiquated equipment closed the mill in 1928.

In 1946, the mill and surrounding property was conveyed from Thomas H. Hartman to the Western Pennsylvania Conservancy and later to the Commonwealth of Pennsylvania with the wish that it be preserved for future generations. McConnells Mill State Park was formally dedicated in October of 1957.

McConnells Mill Covered Bridge

One of two covered bridges in Lawrence County, it was built in 1874 and is of Howe Truss design. A registered National Historic Landmark, the bridge is on state park land but is the property of Lawrence County.
