About this map

Lake Mead dominates the southern landscape of this Clark County quadrangle, where its waters back into the deep cuts of Boulder Canyon. The shoreline is characterized by a complex series of inlets and coves, including James Bay, Gordys Cove, and Flamingo Cove, while the East End Light serves as a lone navigational marker on the water. This topography reveals a stark contrast between the reservoir and the arid high ground of the Pinto Valley and Bitter Spring Valley to the north.

Prominent geological formations rise sharply from the water's edge, notably Arch Mountain and the Stewart Cliffs at the southern boundary. To the north, the landscape is defined by ridges and peaks like Razorback Ridge, Boulder Peak, and Saddle Mountain. Seasonal drainages such as Boulder Wash cut through the desert floor, leading toward the Gypsum Beds and Little Gyp Beds, illustrating the erosional forces that have shaped this portion of the Mojave Desert.
