2011 Map of Petroglyph Wash

About this map

Lake Mead defines the northern and eastern fringes of this Mojave County landscape, where the desert floor meets the irregular indentations of the Colorado River's impounded waters. The map details a series of distinct inlets along the reservoir, including Canyon Point Cove, Sidewinder Cove, James Bay, and Teakettle Bay. Inland, the terrain is dominated by the drainage system of Petroglyph Wash, which carves a path through the arid flats toward Petroglyph Bay. To the west, the rising elevations of Wilson Ridge overlook the basin, while Wildhorse Spring marks a rare water source in the southern sector. Transportation is limited to a few arterial routes such as Bonelli Landing Rd, reflecting the remote character of this region. This survey captures the relationship between the engineered shoreline of the lake and the ancient natural features like Gilbert Canyon that predate the reservoir.
