The Allegheny River of western Pennsylvania and New York rises in Potter County, Pennsylvania, and flows 320 miles to its confluence with the Monongahela River in Pittsburgh. The Allegheny's southern watershed district begins in East Brady, Pennsylvania, and ends in Pittsburgh, and it includes the historic Redbank Creek, Mahoning Creek, Crooked Creek, and Kiskiminetas River valleys. Along the Allegheny River: The Southern Watershed features over 200 vintage postcards of the landscapes, people, industries, and events that shaped the history of the southern Allegheny River Valley and of the nation. These absorbing images chronicle over 200 years of history from the frontier wars of the 18th century to the rise and growth of

the Industrial Revolution in the late 19th and early 20th centuries.
