2017 Map of Lord Flat

About this map

Snake River navigation and high-elevation plateaus define this borderland where Oregon and Idaho meet. This 2017 survey details the dramatic transition from the river canyon floor to the surrounding highlands of the Wallowa National Forest and Nez Perce National Forest. The river course is marked by significant water features including Cottonwood Rapids, Somers Creek Rapids, and Davis Creek Rapids, illustrating the challenging hydrology of the canyon. Above the water, names like Lord Flat, Mormon Flat, and Englishman Hill suggest a history of localized grazing and early land use. The topography is deeply dissected by drainages such as Buckaroo Gulch, Cache Canyon, and Big Canyon Cr, while access is maintained via the remote Highrange Road and Lookout Road.
