1983 Map of Iceberg Canyon

About this map

Lake Mead National Recreation Area dominates this early 1980s landscape, where the waters of the Colorado River meet the complex geology of the Nevada-Arizona border. The map illustrates a high-water environment within Gregg Basin, featuring numerous intricate inlets such as Devils Cove, Lime Cove, and Sunfish Cove. The rugged elevation is defined by Iceberg Ridge and Wheeler Ridge, providing a sharp contrast to the submerged topography of the Iceberg Canyon itself. To the north, the arid terrain of the Milton Hills and Million Hills is etched with drainage patterns like Connoly Wash and New Spring Wash, leading toward isolated water sources including Connoly Spring. The survey clearly delineates the fluctuating nature of the shoreline, noting the normal pool and spillway elevations near landmarks like Driftwood Island and Cormorant Cliffs.
