Dilliner, Pennsylvania

Dunkard Creek is a stream that flows 36.9 miles (59.4 km) through Greene County, Pennsylvania and Monongalia County, West Virginia, near the towns of Mount Morris, Pennsylvania, and Blacksville, West Virginia. It flows into the Monongahela River northwest of Point Marion, Pennsylvania, approximately three miles north of the Pennsylvania-West Virginia border. Mason-Dixon Historical Park is located on the banks of Dunkard Creek in an area where the creek crosses the border three times in less than one mile. The park grounds include Brown's Hill, the westernmost site from which Charles Mason and Jeremiah Dixon made astronomical observations during the original survey of the Pennsylvania–Maryland border in 1767.The creek is named for members of the Dunkard Brethren, a pacifist, nonconformist group of Christians who settled in the region during the 18th century and practiced baptism by immersion. The Pennsylvania German word for "immerse" is dunke and people who immerse are called dunker. In September 2009, Dunkard Creek suffered a massive fish kill resulting in the death of more than 160 species of fish, salamanders and endangered mussels in the creek. The West Virginia Department of Environmental Protection determined that an algal bloom was responsible for the loss. The bloom is believed to have been possible as a result of high chloride and salt levels in the water. A Consol Energy mine discharge site on the creek is the likeliest source of contamination. The Shannopin Mine in the Bobtown area of Dunkard Township also discharges into Dunkard Creek. Since at least 2002, the West Virginia DEP had known about and been pressured by environmental groups to take action on high levels of chlorides and other contaminants in the Blacksville No. 2 outfall, but they took no action against Consol. In March 2011, Consol Energy reached an agreement with the US EPA and the State of West Virginia regarding damage done to Dunkard Creek caused by high levels of TDS in the discharge from their Blacksville No. 2 mine. As part of that settlement, Consol agreed to pay $5.5 million in civil penalties for pollution violations related to the 2009 fish kill. The settlement also describes requirements for Consol to complete a new, $200 million water treatment system to better control pollution discharges from its active and former mining operations in the area. In July 2015, Consol Energy reached a settlement with the PA Fish and Boat Commission, agreeing to pay $2.5 million for the damages to the Pennsylvania portion of Dunkard Creek. The commission plans to use this money to restore the fish population in the creek and support recreational fishing and boating projects.

The Cheat River is a 78.3-mile-long (126.0 km) tributary of the Monongahela River in eastern West Virginia and southwestern Pennsylvania in the United States. Via the Ohio River, the Cheat and Monongahela are part of the Mississippi River watershed. Owing to the ruggedness of the surrounding Allegheny Mountains, the Cheat remains largely remote with few settlements or developments along its banks. Its headwaters are in the Cheat-Potomac Ranger District of the Monongahela National Forest.

The Albert Gallatin Memorial Bridge (also known as the Point Marion Bridge) was a cantilever truss bridge that carried vehicular traffic across the Monongahela River in the southwestern part of the U.S. state of Pennsylvania. Built in 1930 to replace a ferry, it connected Point Marion in Fayette County and Dunkard Township in Greene County. It was named in honor of U.S. Senator, and longtime U.S. Treasury Secretary and diplomat Albert Gallatin, whose Friendship Hill homestead is nearby.

Cheat Canyon — also called Cheat River Canyon or Cheat River Gorge — is a 10-mile (16 km) long, forested Canyon of the Cheat River at the western edge of the Allegheny Mountains in northeastern West Virginia, United States. A popular whitewater venue, for many years the Canyon has been the object of controversy as environmental activists have contended with timber and development interests over its preservation status.

Point Marion Lock and Dam, previously known as Lock and Dam Number 8, is one of nine navigational structures on the Monongahela River between Pittsburgh, Pennsylvania and Fairmont, West Virginia. Maintained and built by the U.S. Army Corps of Engineers, the gated dam forms an upstream pool that is 11.2 miles (18.0 km) long, stretching to the base of the Morgantown Lock and Dam. It is located at river mile 90.5 (river kilometer 145.6). There is one lock chamber on the left descending bank of the river at the dam, 84 feet (26 m) wide and 720 feet (220 m) long. The reservoir formed by the dam is also a municipal and industrial water supply.

Stewartstown is an unincorporated community in Monongalia County, West Virginia, United States. William Stewart and his wife Elizabeth Givens Stewart originally settled Stewardstown in 1771. It lies in the region of Monongalia County known as The Forks of Cheat, so named because that is the area where the Cheat empties (forks) into the Monongahela River. It is nestled close to the Cheat River, off US-119 on a bend in the river. There in 1775, Rev John Corbly organized the Forks-of-the-Cheat Baptist Church, the oldest continuously operating church in West Virginia.
