1981 Map of Helvetia
USGS Topo · Published 1985About this map
Mining operations and cattle ranching dominate this corner of the Santa Rita Mountains, where the 1981 landscape is defined by its deep canyons and legacy of extraction. The former community of Helvetia is noted here as a site, accompanied by the nearby Helvetia Cem, serving as a silent reminder of the area's copper mining boom. The eastern slopes are riddled with historical claims including the Narragansett Mine, Omega Mine, and Copper Duke Mine, while the southern reaches towards Greaterville show the transition from the high peaks to the gulches of the Santa Ritas.
