Umatilla National Forest occupies a significant portion of this landscape in Morrow County, characterized by a complex network of canyons and upland springs. The namesake Lake Penland sits in the northern reaches, serving as a focal point above Brown Prairie. The terrain is deeply incised by drainages such as Potamus Creek and Little Potamus Creek, which define the local topography alongside the prominent rise of Potato Hill.
