1971 Map of Smelter Knolls East

About this map

Topaz Camp (Site) stands as a significant historical footprint on this 1970s landscape in Millard County, marking the location of the former internment center. The surrounding terrain is defined by the stark topography of the Smelter Knolls and the prominent ridge known as Hogs Back. Water management in this arid Great Basin environment is evident through features like the Abraham Reservoir, the Abraham Canal, and Topaz Slough. The area's geological and industrial character is further noted by several Borrow Pit locations, Gravel Pits, and a Mine tucked into the knolls. Traces of the ancient landscape remain visible in the Old River Bed Depression, while a network of Jeep Trails provides the primary means of navigating the desert flats and muddy lowlands of the Mud flats.
