About this map

Spencer sits along the Union Pacific rail line in this 1970s survey of eastern Idaho. The landscape is defined by the drainage of Beaver Creek and the steep terrain of the Targhee National Forest. A significant portion of the southern area is dedicated to the U S Experiment Station, illustrating the region's historical importance to livestock and range research.

The map highlights a transition from the narrow corridor of Huntley Canyon to the broader flats where the railway and Highway 91 parallel each other. Geological and hydrological points of interest are numerous, including The Crater and several Caves, alongside local water sources like Threemile Res and Bed Springs. Numerous Borrow Pits along the transportation routes reflect the infrastructure maintenance required for this mountain passage.
