1967 Map of Torres

USGS Topo · Published 1986

About this map

The Maxwell Grant boundary cuts through this high-altitude landscape of southern Colorado, defining a territory where ranching and mining history intersect. The Purgatoire River and its tributaries, including the South Fork Purgatoire River, provide the primary drainage for the area, supported by a complex network of historic irrigation systems such as the Consolidated Ditch and South Valley Ditch. Evidence of the region’s industrial past is seen in the Old Railroad Grade winding toward the settlement of Tercio, once a significant coal mining hub. Local genealogy is anchored by the Tercio Cem and scattered sites like Torres and Sheep Camp. Higher elevations feature landmarks like San Francisco Pass and the distinctive geological formation known as The Little Wall, while extraction history is preserved at the Cornell Mine and Quatro Mine.
