About this map

The Fort Hall Indian Reservation occupies the western portion of this 1916 survey, where the Portneuf River and Deadman Creek flow through the valley floor. To the east, the Blackfoot Mountains dominate the landscape, separating the reservation from Paradise Valley. The rugged character of the terrain is marked by features like High Basin Ridge and the volcanic expanse of the Willow Creek Lava Field in the northeast corner.

Settlement is sparse, concentrated near water sources and travel routes. Small outposts such as Morgan, Aldridge, and the Austin Ranch provide rare points of human development amidst the network of waterways like the Blackfoot River and Beaver Creek. The map documents the early political geography of the region, clearly delineating the Bingham Co Bannock Co boundary line as it crosses the high ridges and canyons of southern Idaho.
