2013 Map of Black Canyon

About this map

Heringa Ranch and its surrounding high plains landscape define this section of Union County, where life revolves around the scarce water resources of the high desert. The drainage of Perico Cr carves through the terrain, most notably at the namesake Black Canyon, while Carrizo Cr clips the southwestern corner. This is a region defined by ranching infrastructure, where water for livestock is secured through a series of named landmarks including the Rummel Windmill, Myers Windmill, and Bull Pasture Windmill. The map traces the essential roadway network of the era, from the long stretch of Heringa Rd to CO Highway A-016 and CO Highway A-017, providing a precise record of how these remote ranchlands were accessed and maintained.
