Pyramid of the Sun. At the city of Teotehuacan (please see last frame). This is the largest of the two Pyramids, and the largest one in this hemisphere. Its base is as large as that of great Pyramid at Giza and it's over 200 feet tall. They say to show scale, to insert people. I found a couple standing on the edge and took the shot. A telephoto zoom lens to crop the shot and show the scale of the pyramid. Nikon N70, 70-210mm, tripod. Film--Sensia.
