The Portneuf Range anchors this high-elevation landscape within the Caribou National Forest along the border of Bannock and Caribou counties. The map documents a working wilderness characterized by seasonal camps and forest management, featuring the Bear Camp settlement and the Pebble Guard Station near Big Spring. These points of interest, along with the Pebble Cow Camp, suggest a history of grazing and government oversight in the Idaho backcountry. Water remains a defining element of the terrain, from the Portneuf River in the southeast to the isolated Horse Lake and numerous drainage systems like N Fork Pebble Cr and Toponce Cr. The intricate network of canyons, including Gooding Canyon and Dumont Canyon, illustrates the complex geography that has shaped local transportation routes such as Toponce Canyon Rd and Maggies Rd.
