1971 Map of Hidden Valley Ranch

About this map

The Apishapa River carves a deep path through this high-plains landscape in Las Animas County, as seen in this early 1970s survey. The terrain is defined by dramatic breaks like Cordova Mesa and Black Bluff, transitioning into the expansive Tyrone Flats to the south. Water management for ranching and wildlife is central to the area's layout, evidenced by the Apishapa Game Management Area and a network of named water sources including Springer Well, Monroe Well, and Sulfur Well. Genealogists and local historians can locate the isolated Thorp Cem in the northeast and trace the roads leading to the Hidden Valley Ranch. The map also documents resource extraction efforts with several labeled sites like Sorgs and various drill holes scattered across the drainage of East Arroyo and Smith Hollow.
