1980 Map of Broken Wagon Flat

About this map

Missile Base and the associated Missile Base Road highlight a Cold War military presence in this high-desert portion of Owyhee County. The landscape is defined by vast, open grazing lands and water management features essential for range life, such as the Broken Wagon Flat Reservoir and a Horse Trap (Corral). Located between the elevations of Big Hill and Horse Hill, the area shows a network of remote infrastructure including the CCC Road and several gravel pits, indicating both mid-century public works projects and local resource extraction. Water sources are scarce, marked by drainage systems like Sugar Creek and Hot Creek, as well as the notable Windy Well (Dry). The map reflects a working landscape where ranching, transit via the Blackstone Road, and national defense interests converged in the late 20th century.
