1971 Map of Smelter Knolls East

About this map

The Topaz Camp (Site) in Millard County marks a significant historical location within this 1970s landscape, providing a geographic record of the site decades after its wartime use. The surrounding desert environment is defined by the Old River Bed Depression, an ancient watercourse that cuts through the arid basin. To the west, the volcanic landforms of Smelter Knolls rise sharply from the valley floor, accompanied by the distinctive Hogs Back ridge. Water management is central to the area's utility, evidenced by the Abraham Canal, Abraham Reservoir, and the Little Drum Reservoir. The map also captures several industrial and agricultural features, including a Storage Bin, multiple Mine sites, and a network of Jeep Trails that navigate the varied terrain of the Sevier Desert.
