1966 Map of Monument Butte

About this map

Iles Mountain dominates the northern landscape of this Moffat County region, where the high-altitude terrain transitions into the resource-rich Axial Basin. This 1966 field-checked survey highlights the industrial footprint of the Iles Dome Oil Field, characterized by a network of pipelines and an isolated Oil Well south of the mountain's ridge. Evidence of early settlement and ranching is found at the Loyd (Site) and Iles Grove, located near the intersection of the basin's drainage systems. The map details a complex network of seasonal water sources and canyons, including Stinking Gulch, Milk Creek, and Sulphur Gulch. Notable for local historians and land use researchers, the sheet also marks Gravel Pits and various jeep trails that navigate the steep slopes leading up to Monument Butte and Thornburg Mountain.
