About this map

Shivwits Plateau dominates this high-altitude landscape in the late 1960s, where dramatic elevation changes define the northern reaches of the Lake Mead National Recreation Area. The terrain is deeply incised by complex drainage systems, including the massive Surprise Canyon and the forks of Separation Canyon. Human presence is minimal, evidenced only by scattered resources like a solitary Corral and a network of unimproved dirt roads that navigate the plateaus and points.

Vital water sources are identified throughout the arid environment, such as Amos Spring, Horse Spring, and Twin Springs, which were essential landmarks for any traveler or rancher moving between Amos Point and Twin Point. The map reflects a period of intense topographic study by the Geological Survey, using 1966 aerial photography to document the intricate relationship between the flat-topped mesas and the steep descents into Green Spring Canyon and other tributaries of the Colorado River system.
