About this map

Hurricane Cliffs dominate the western edge of this topographic study, marking a dramatic geological transition in this corner of Mohave County. In the early 1970s, this landscape was defined by its sparse water infrastructure, with livestock tanks such as Turn Wash Tank, Shanley Tank, and Nickals Tank serving as vital hubs for the surrounding rangeland. The terrain is characterized by distinct landforms like the central Moriah Knoll and the sweeping Lonesome Valley to the north.

The intricate network of dry washes and drainage patterns, including Langs Run and the southern Dutch Valley, illustrates the importance of seasonal water management in the high desert. Prominent rock formations like The Black Rocks and the distinctive Seven Knolls provide natural landmarks for navigation in a region without permanent settlements. These features suggest a landscape primarily utilized for cattle ranching, where family-named features like Berry Knoll and Jodys Lake indicate a long-standing human connection to specific parcels of land.
