About this map

The Mount Bennett Hills dominate this high-desert landscape in south-central Idaho, where a complex network of water management features sustained the ranching and agricultural life of the mid-1950s. Multiple reservoirs, including McHan Reservoir, Thorn Creek Reservoir, and the Portuguese Reservoir, capture runoff from the drainages of Willow Creek and Thorn Creek. These water sources are vital in a terrain marked by numerous springs such as Mud Spring and Eureka Spr.

Lower elevations toward the southern boundary transition into more developed land near the Big Wood River, where the infrastructure of the Union Pacific railroad and a large Ditch and Canal system emerge. Local landmarks like the Thorn Creek School and a Landing Strip reflect the social and logistics hubs for isolated homesteads. The map also documents distinctive geological features, from the heights of Johnson Hill to the uniquely named Turkey Head Butte, providing a detailed view of how early settlers adapted to the volcanic terrain and arid climate of the Snake River Plain periphery.
