Travel Tuesday - Lake Mead and the Davis Dam    NEW!

The Colorado River makes a sharp turn southward after Grand Canyon and continues on to Laughlin, Nevada on its west shore and Bullhead City, Arizona on its east shore. The Davis Dam herds some of that water for hydroelectric power, forming the southern tip of Lake Mead. We’ll learn how the dam works and how it promotes irrigation and flood control as we “tour” the dam and the Lake Mead National Recreation Area’s hiking, driving, exploring and boating.
