1970 Map of Bullis Mills

About this map

Bullis Mills and the surrounding borderlands of McKean County sit at a geographic crossroads where the Allegheny River and Oswayo Creek meet the New York state line. In 1970, this region remained heavily defined by its industrial roots, with the Sartwell Oil Field and numerous scattered Gas Wells and Oil Wells dotting the deep valleys and ridges. Transportation infrastructure tells the story of changing eras, from the active Penn Central line crossing the river to a bypass of the Old Railroad Grade near the northern border.
