2021 Map of Hiller Mountains

About this map

Lake Mead National Recreation Area dominates this landscape where the Colorado River's impounded waters reach into the desert topography of Clark County, Nevada, and Mohave County, Arizona. The map details the transition from the high ridges of the Hiller Mountains and Gregg Peak down to the complex shoreline of Lake Mead. In the southern portion of the sheet, the waters of Virgin Canyon and Gregg Basin meet, creating a network of inlets such as Gold Cross Bay and Reef Bay. The presence of named points like Greggs Hideout and Rocky Point suggests the recreational and navigational importance of these waters, while interior features like Jumbo Pass and Burro Spring indicate the sparse but vital water sources and travel routes through the surrounding Mojave Desert. This 2021 survey illustrates the modern extent of the reservoir against the backdrop of ancient terrain features like Temple Mesa.
