About this map

The Raft River Valley dominates this Idaho landscape, where the waters of the Raft River flow northward to meet the Snake River. In the northern reach of the sheet, the Minidoka National Wildlife Refuge protects the riverine environment near Tule Island. The small settlement at Raft serves as a focal point for local transport, situated near where the Raft River crosses under the main highway routes.

Southward, the terrain rises steadily toward the summit of North Chapin Mtn, dissected by drainage systems like Calder Creek and Lanes Gulch. The map reveals a structured network of rural routes, including Heglar Canyon Rd and Yale Rd, which follow the natural contours of the canyons and ridges. This modern survey illustrates the persistent importance of water and elevation in defining the limits of settlement and land use in Cassia County.
