About this map

Ferguson Desert and the high ridges of the Confusion Range define this high-altitude landscape in western Millard County. The map details a remote desert environment where water sources and livestock management are the primary markers of human presence. Isolated features such as Probst Pond and the Probst Corral suggest the area's importance for local ranching, while Ecks Knoll Reservoir sits at the southern edge of the quadrangle near Ecks Knoll.
