Frisco and the mining landscape of the San Francisco Mountains dominate the eastern edge of this late 1950s survey. This region was once a major silver-producing district, evidenced by the cluster of shafts including the Carbonate Mine, Imperial Mine, and Washington Mine. The map traces an Old Railroad Grade winding through Copper Gulch toward the high-elevation workings of Grampian Hill.
