1982 Map of Soda Springs

About this map

Soda Springs serves as the industrial and hydraulic hub of this Idaho landscape, where the Bear River is controlled by the Alexander Reservoir at the western edge of town. The area’s mineral wealth is evident in the sprawling Phosphate Plant and the mining community of Conda to the northeast. Beyond the rail lines of the Union Pacific, the geography is defined by a series of significant thermal and mineral waters, including Hooper Spring, Mammoth Spring, and the unique geological features of Formation Spring and Formation Cave. The eastern portion of the map climbs into the Aspen Range, revealing the site of the Idaho Sulphur Mine and Dewey Sulphur Mine tucked into Sulphur Canyon. This combination of heavy industry, rail transport, and diverse water sources highlights the complex economic and natural history of the Caribou County region.
