Dead Man's Hollow is a 450-acre conservation area along the Youghiogheny River south of McKeesport, Pennsylvania, spanning Liberty Borough, Lincoln Borough, and Elizabeth Township. Established in 1996 and managed by Allegheny Land Trust, it is known for both woodland restoration and the preserved remains of late nineteenth-century industries, including the Bowman Brickyard and Union Sewer Pipe Company, which ended after a fire in 1920. Volunteers have helped restore native habitat, and the area supports wildlife and gained designation as a Wild Plant Sanctuary in 2017. With more than eight miles of trails, it brings together public recreation, industrial archaeology, habitat protection, and longstanding local ghost lore.
