1968 Map of Quartermaster Canyon

About this map

Lower Granite Gorge forms the dramatic centerpiece of this late-1960s survey, where the Colorado River carves through deep canyon walls. This specific reach includes Wards Cave Rapids and a marked Waterfall, emphasizing the river's character before it reaches the full extent of Lake Mead. The map reveals a strict divide between the Hualapai Indian Reservation and the Lake Mead National Recreation Area, with an Indefinite Boundary tracking the high plateau above Quartermaster Canyon. Human presence is minimal, defined primarily by survival infrastructure like Granite Tank, Smith Tank, and New Water Tank. Access to the rim is limited to the Buck and Doe Road and a solitary Jeep Trail, leading to the Quartermaster View Point overlooking the immense verticality of Jeff Canyon.
