The Flathead Indian Reservation dominates this landscape in western Montana, where the Little Bitterroot River meanders south through a broad valley flanked by high ridges. This 1988 revision, based on earlier data from the Bureau of Indian Affairs and the USGS, captures a semi-arid ranching and reservation environment defined by its water management. The Camas Canal and various flowing wells highlight the human effort to divert water toward the small settlement at Camas. In the rugged eastern terrain, narrow drainage systems like Garceau Gulch and Irvine Creek cut through the high country, while Camp Aqua sits along the river bottom, suggesting the area's local significance as a gathering place or thermal site. The map clearly delineates the administrative boundary between Lake and Sanders Counties, tracing the divide through the Little Bitterroot River corridor.
