About this map

The San Luis Hills rise above the confluence of ancient irrigation networks and mountain waterways in this late 1960s study of Conejos County. The landscape is defined by the winding Conejos River and Rio San Antonio, which feed a complex system of gravity-fed waterworks including the East Bend Ditch and Eightmile Ditch. These ditches underscore the region's long-standing reliance on communal water management to sustain high-altitude agriculture.

Evidence of mineral extraction and early settler life is scattered across the volcanic terrain, most notably at the Kings Turquoise Mines and various unnamed prospects in the southeastern quadrant. Local history is anchored by the Lasauses Cem near the riverbanks and the presence of named water sources like Emory Orr Spring, providing specific points of interest for genealogists tracing families in the southern San Luis Valley. The map also captures the distinct topography of the Piñon Hills and the aptly named Flat Top.
