1983 Map of Boulder Canyon

About this map

Lake Mead and the Colorado River dominate this desert landscape, where the waters of the impounded river wind through the dramatic topography of Boulder Canyon. Surveyed in the early 1980s, the map documents the complex shoreline of the Lake Mead National Recreation Area, highlighting numerous named inlets such as Wishing Well Cove, Gordys Cove, and Canyon Cove. The terrain is defined by prominent ridges and peaks, including the Black Mountains, Arch Mountain, and Razorback Ridge, which separate the expansive Bitter Spring Valley from Pinto Valley. The geological transition at The Narrows and the broad expanse of the Virgin Basin provide a detailed look at the hydrology of the region as it appeared before modern shoreline shifts. Notable landmarks like Sandstone Spring and Little Gyp Beds offer specific points of interest for those studying the natural history of this Nevada-Arizona borderland.
