The Allegheny National Forest dominates this McKean County landscape, where deep-cut valleys and high plateaus reveal a region heavily defined by natural resource extraction during the mid-1960s. Oil wells and gas wells are scattered across the terrain, particularly near Marshburg and the Klondike area. The topographic data reflects the environmental shifts of the era, most notably the presence of the Allegheny Reservoir along the western edge, created by the damming of the Allegheny River.
