1966 Map of Monument Butte

About this map

The high plateau and drainage basins of Moffat County are defined here by the Iles Dome Oil Field, a landscape marked by scattered oil wells and pumping stations. Near the center of the sheet, the former settlement of Loyd is noted as a site, while early watering points like Ralston Springs and the sheltered Iles Grove provided essential stops in this arid terrain. The map's topography is dominated by the massive ridge of Iles Mountain and the distinct peak of Monument Butte, which overlooks a complex network of seasonal drainages including Stinking Gulch and Seeping Spring Gulch. To the south, Thornburg Mountain rises above the Milk Creek valley, where a series of jeep trails and gravel pits suggest a landscape driven by resource extraction and ranching at the time of the 1966 field check.
