The map documents the heavy infrastructure of the era, including the Smelter, Slag Dump, and the Magma Arizona railroad line that serviced the works. Beyond the immediate town site, the terrain is marked by numerous historical workings such as the Silver King Mine and Fortuna Mine, illustrating a cycle of boom and depletion in the surrounding mountains.
