About this map

Mineral Mountains dominate this survey area, where a high-desert landscape is defined by its geological utility and sparse water sources. The map shows a clear industrial and exploration focus, with several Mines and numerous Prospects scattered across the higher elevations, particularly around Antelope Mountain. This concentration of extraction sites suggests a period of active mineral interest in the early 1970s.

Water management is critical in this arid terrain, evidenced by the presence of Salt Cove Reservoir, Salt Spring, and Hodgson Pond. Human infrastructure is otherwise limited to a network of Jeep Trails and a solitary Radio Facility, while the jagged crossing at Pinnacle Pass serves as a key landmark. The boundary between Millard and Beaver Counties runs across the center, including a section marked as an Indefinite Boundary, likely due to the complex topography.
