About this map

Ralston Buttes rises sharply over a landscape defined by deep gulches and early industrial extraction during this mid-1960s survey. The Denver and Rio Grande Western railroad corridor traces the eastern edge through Rocky Flats, serving the local mineral economy including a Fire Clay Mine and various Prospects. The terrain is characterized by steep drainages like Van Bibber Creek and Sawmill Gulch, revealing a network of primitive access routes and Jeep Trails that connect remote landmarks.

Evidence of ranching and early habitation appears at Centennial Ranch and along the Robinson Hill Road. The map documents a transition between the high peaks of Centralia Mountain and Mount Tom and the burgeoning water infrastructure at Ralston Res. Geologists and local historians can trace specific land-use patterns from Golden Gate Canyon up to the prominent Centennial Cone, illustrating the intersection of mining claims and rugged Colorado geography.
