1989 Map of Pine Valley Hardpan North

About this map

The Desert Experimental Range occupies the central and western expanse of this high-desert basin, illustrating federal land management and ecological study in the late twentieth century. This arid landscape is dominated by the vast Pine Valley Hardpan and the broader Pine Valley, where water is a scarce and vital resource. The presence of Guyman Well provides a rare point of human infrastructure in an otherwise remote terrain, while the Tunnel Spring Mountains rise to the northwest to define the basin's edge. Transportation is limited to rugged tracks and the Sand Pass Road, reflecting the area's isolation and its primary use for scientific observation and open-range livestock management. The map details the Township and Range boundaries, such as T 24 S and T 25 S, which organize this sparsely populated portion of Millard County.
