About this map

The extraction landscape of McKean County dominates this 1969 survey, where the Marshburg Oil Field and Lewis Run Oil Field underscore the region's industrial heritage. Numerous drill holes and gas wells are scattered across the slopes of Music Mountain and Cherry Hill, illustrating a late-twentieth-century peak in local resource development. The Baltimore and Ohio Railroad winds through the eastern valleys, serving established communities like Lewis Run and the smaller settlements of Irishtown and Big Shanty.

Civil development is anchored by the Bradford Regional Airport and the crossroads at Lafayette, where the Ryan Sch and McKean Memorial Park are located. Much of the western terrain is protected within the Allegheny National Forest, where the topography is cut by Kinzua Creek and its many tributaries, including Wintergreen Run and Windfall Run. Traces of older transport networks remain visible, including an Old Railroad Grade near Mount Alton.
