About this map

The Fort Hall Indian Reservation dominates the western portion of this 1916 survey, where the rugged terrain of the Blue Mountains and High Basin Ridge meets the volcanic activity of the east. A prominent Lava Field marks the northeastern corner near Willow Creek, contrasting with the more traditional river valleys to the south. The drainage network is complex, defined by the Blackfoot River as it snakes through the lower elevations and the Portneuf River visible near the southern boundary.

Early Idaho ranching and settlement patterns are evident in the presence of Aldridge, Morgan, and the Austin Ranch. These locations, along with the broad expanse of Paradise Valley, reflect the importance of water access in this high-desert environment. The map captures a moment before modern development, showing the transition between the Bingham, Caribou, and Bannock county lines as they were understood just after the first World War.
