About this map

The eastern reaches of the Fort Hall Indian Reservation dominate this section of Caribou County, where the Old Indian Reservation Boundary cuts through the high desert and mountain landscape. Water management is a primary theme of the terrain, centered on the Chesterfield Reservoir and the Portneuf Canal, which facilitate irrigation for the Portneuf Valley. The hydrological network is dense, featuring numerous seasonal and perennial flows such as Warbonnet Creek, Jeff Cabin Creek River, and Twentyfour Mile Creek.

Along the rugged Chesterfield Range, family names and local landmarks like Jim Cornelius Canyon and Hibner Springs mark the geography of early ranching and settlement. The presence of Horse Camp and a Prospect suggests the historical use of these uplands for livestock and small-scale mineral exploration. For those tracing the movement of people across the Idaho territory, the map also identifies the route of the Portneuf Trail winding through the western canyons.
