About this map

The Cortez Mountains dominate this 1980s landscape, a high-desert terrain defined by the essential search for water and minerals. Resource extraction is a primary focus of the era, most notably at the Open Pit Modarelli Mines in the northern reach of the quadrangle. Surrounding this industrial hub are numerous exploration sites labeled simply as Prospect or Prospects, alongside a specific Tunnel near Sheep Creek Canyon, tracing the persistent efforts of miners to tap the region's geologic potential.
