Nevada Medal Lectures In this lecture Professor
El-Baz will illustrate, with color images, how the last major drought in
North Africa 5,000 years ago may have ignited the spark that initiated civilization
in the Nile Valley, and how the immigrants from the deserted land may have
brought with them knowledge of the endurance of pyramidal structures in
that windy environment and the natural landforms of wind-eroded rocks in
the shape of the Sphinx.
The lectures are free and open to the public. Reno Lecture Las Vegas Lecture
