1971 Map of Mt. Dellenbaugh

About this map

Mt Dellenbaugh dominates the high ground in this 1970s survey of the Arizona strip, where the transition from high plateaus to the canyonlands of the Lake Mead National Recreation Area is sharply defined. The terrain is marked by deep incisions like Twin Spring Canyon and Green Spring Canyon, which channel seasonal runoff toward the Colorado River system. This landscape reflects a critical water-management history for western ranching, evidenced by the scattered network of named water sources such as Mathis Spring, Suicide Tank, and Lower Spring. Beyond the natural drainage, the presence of a lone Jeep Trail cutting across the northern reaches illustrates the limited access and land use patterns of this remote Mohave County interior before modern infrastructure reached the rim. Large promontories like Twin Point and Suicide Point provide significant vertical relief, showing the complex geological layering of the region.
