Hawk Mountain Sanctuary
Located on the Kittatinny Ridge of Central Appalachian Mountains in eastern Pennsylvania, Hawk Mountain Sanctuary's landscape is second-growth mixed deciduous forest, including oak-maple forest on the mountains and rolling, partly wooded, farmland and Christmas-tree plantations in the valleys. The Appalachian Trail abuts Hawk Mountain Sanctuary on the eastern border and state gamelands border sanctuary forest to create 15,000 acres of protected lands. Visitor facilities include a visitor center with a raptor exhibits and bookstore with free programming on weekends during spring and fall. The Sanctuary, which is open year-round, attracts more than 80,000 visitors annually, with as many as 3,000 visitors on some weekend days in October. The Sanctuary has 10 lookouts and 15 km of trails. An admission fee is charged for access to the trails and lookouts. The Sanctuary's long-term count site, the North Lookout, is a 465-m rocky outcrop with a 240° view to the northeast, 1.5 km from the Visitor Center parking lot. Raptors slope-soar along the Kittatinny Ridge and thermal-soar over adjacent valleys at the site. Migration is most pronounced on northwest winds, especially on the first two days following the passage of a cold front.
