Lake Mead National Recreation Area
Location Map This view is along Highway 165 in the Eldorado Mountains near the town site of Nelson, Nevada. The mountains consist of eroded remnants of late Tertiary volcanic rocks (intrusions, stocks, dikes, flows, tuffs, and ash beds) and alluvial sedimentary deposits (Beard and others, 2007). The massive layers of volcanic rock and sedimentary material gently dips to the east toward the Colorado River Valley.
