2010 Map of Derrick City

About this map

Derrick City and the surrounding drainages of McKean County define this 2010 survey of the northern Pennsylvania borderlands. The landscape is characterized by a series of deep hollows and runs, including Buchanan Hollow, Tibbitts Hollow, and Garlock Hollow, which dictate the winding paths of roads like Red Rock Rd and Dallas Rd. Small residential clusters such as Beechwood Heights, Fairview, and Sawyer City are scattered across the hillsides, connected by a network of creeks like Kendall Creek and Knapp Creek. South of the higher elevations, the terrain levels into the settlements of Aiken, Allen, and Middletown. The map shows a clear pattern of development constrained by the steep topography of the Allegheny Plateau, with larger centers like Foster Brook concentrated near the broader valley of Tunungwant Creek.
