About this map

Petroglyphs and freshwater sources define this 1970 desert landscape within the Newberry Mountains. This map documents a region where ancient cultural markers meet modern infrastructure, notably at Hiko Springs and along the eastern reaches of the Lake Mead National Recreation Area. The terrain is characterized by deep erosional features like Grapevine Canyon and Bridge Canyon, which provide critical drainage for the seasonal Grapevine Wash.

Evidence of human activity is scattered throughout the canyons, ranging from an old Corral and a Dry Well to contemporary Radio Facilities and a power Substation. The presence of Dripping Springs and Sacatone Spring highlights the vital importance of water in this arid environment, while a Jeep Trail provides the primary means of navigating the steep elevation changes between the peaks and canyon floors.
