The Sawtooth Mountains and Pioneer Mountains dominate the northern skyline of this mid-century survey, a landscape defined by high-altitude mining operations and the developing recreation economy around Sun Valley. To the east near Hailey and Ketchum, several specific industrial sites are noted, including the Silver Star Queens Mine, Triumph Mine, and North Star Mine. The terrain transitions sharply from these jagged peaks to the high desert plains and irrigation-fed agricultural lands of the south, where the Union Pacific railroad corridor connects settlements like Glenns Ferry and Mountain Home. This era represents a significant period of water management in the region, evidenced by the large-scale footprints of the Anderson Ranch Reservoir, Magic Reservoir, and Mormon Reservoir. The map also captures the strategic military presence at Mountain Home Air Force Base, positioned on the flatlands south of the Danskin Mountains.
