The Allegheny River and Oswayo Creek define the northern lowlands of this McKean County landscape, where the settlements of Bullis Mills and Ceres sit near the Pennsylvania-New York state line. The terrain is characterized by a dense network of deeply carved valleys and family-named hollows, including Dutton Hollow, Mix Hollow, and Slippery Elm Hollow. These natural corridors have long dictated the path of local travel, as seen in the placement of Barden Brook Rd and Kings Run Rd.
