"Situated in a broad valley in the Appalachian foothills of north central Pennsylvania, Montour Preserve is surrounded by two long, rolling ridges . Montour Ridge to the south and Muncy Hills to the north. PPL chose this low-lying valley, with its favorable environmental and economic conditions, as the site for the Montour power plant. Built in 1972, the coal-fired power plant is located three miles south of the preserve near Washingtonville. In the center of the preserve is 165-acre Lake Chillisquaque, developed to provide a backup reservoir of cooling water for the power plant. The preserve now offers a variety of educational and recreational opportunities, including hiking, nature observation and photography, birding, boating and fishing, as well as hunting nearby."
