About this map

Grand Canyon National Park and the expansive Lake Mead National Recreation Area dominate this mid-1980s landscape of the Arizona Strip. The high tablelands of the Shivwits Plateau and Uinkaret Plateau are defined by dramatic vertical relief, dropping away at the Grand Wash Cliffs and the deep incision of the Lower Granite Gorge. This era of the map shows a landscape shaped by both geology and isolated human industry, marked by remote mining operations such as the Savannic Mine and the Grand Gulch Mine in the western reaches.

Water sources are critical landmarks in this arid region, from Whitmore Spring to the precarious Lava Falls Rapids on the Colorado River. The map also captures significant cultural and volcanic features, including the Hualapai Indian Reservation boundary and the cinder cone of Vulcans Throne overlooking the inner canyon. Traces of earlier occupation appear at Fort Garrett (Ruins), providing a window into the remote settlement history of Mohave County.
