The Selway Bitterroot Wilderness and Nez Perce National Forest dominate this interior Idaho landscape, defined by a series of high, parallel ridges and the deep drainages between them. Central to the sheet is Twin Butte, a prominent landmark situated at the convergence of several significant terrain features including Pettibone Ridge and Elk Ridge. This topographic study, based on 1960s field data and updated with 1990s imagery, details a roadless environment shaped by natural watercourses.
