1970 Map of Virgin Basin

About this map

The Lake Mead reservoir dominates this landscape where the Virgin River and Colorado River converge across the Nevada-Arizona border. This survey details a transition in the desert landscape as rising waters filled the basin, creating distinct features like Middle Point Islands and Pool Islands. The topography includes the complex underwater contours of Bonelli Bay and Temple Basin, alongside dramatic geological formations such as The Temple, Napoleons Tomb, and The Campanile. Recreational development is evident at the Temple Bar Marina, which features a boat anchorage and ramp, a campground, and a nearby landing field. Local history is captured through markers like the Lakeside Mine and a solitary grave near Gann Spring, reflecting the sparse human presence in the Black Mountains and White Hills.
