Umatilla National Forest encompasses a significant portion of this high-elevation landscape in Morrow County, where a network of forest roads and historic grades navigates a complex system of buttes and canyons. The Heppner-Spray Hwy serves as the primary artery through this terrain, passing through Hayden Prairie and near Camas Prairie. The landscape is characterized by open expanses like Lava Flat and Chapin Meadow, interspersed with prominent landmarks such as Lone Pine Butte and Shingle Mill Butte.
