About this map

Lake Mead National Recreation Area dominates this section of the Arizona desert, where the waters of Lake Mead fill a complex series of canyons and basins. The shoreline is defined by intricate geological formations, from the Gypsum Reefs in the north to the Big Gypsum Ledges and Gypsum Ledges further south. The interaction between the rising reservoir and the arid landscape is visible in features like the Pool Islands and Detrital Reefs, which emerge from the Virgin Basin.

Away from the water's edge, the Mojave Desert terrain rises into the White Hills and drops into the broad Detrital Valley. The drainage of Detrital Wash feeds into Bonelli Bay, carving a path through the alluvial landscape. This 2018 survey provides a modern record of these shorelines and remote coves, such as Secret Cove and Alkali Spring Cove, providing essential detail for navigating this part of the Colorado River system.
