Allegany State Park dominates the western half of this landscape, where the high ridges and deep hollows of the plateau are marked by natural features like Thunder Rocks and the heights of Mt Irvine. The topography is etched by numerous drainages, including Red House Brook and France Brook, which descend toward the broad valley of the Allegheny River. This eastern corridor serves as the primary artery for transportation and settlement, defined by the winding course of Tunungwant Creek and the historical rail crossings at Riverside Junction and Bradford Junction.
