About this map

The San Luis Hills dominate this high-desert landscape in southern Colorado, rising sharply from the surrounding alluvial plains. A complex network of irrigation infrastructure, including the East Bend Ditch, Lasauses Ditch, and Eightmile Ditch, underscores the vital role of water management in this arid region where the Conejos River and Rio San Antonio converge. These waterways historically supported the agricultural life of Conejos County.

Mineral wealth and local landmarks are scattered across the terrain, notably at the Kings Turquoise Mines and various unnamed prospects found near the Fairy Hills. Small-scale historical details, such as the Lasauses Cem and the isolated Emory Ore Spring, provide specific points of interest for genealogists and local historians tracking the early settlement patterns of the San Luis Valley. The southern portion of the map transitions into the Piñon Hills, split by the deeply cut John James Canyon.
