Ukas,
Oh great pyramid maker ... wouldst thou consider making an earthen pyramid based on those built by native Americans along the Mississippi River?
I have attached two images of Monk's Mound at the Cahokia site and I have provided a little information regarding Monk's Mound. The first image shows Monk's Mound in the background. The second image shows Monk's Mound from a second perspective. If you are interested, I would really like two separate earthen pyramids, the smaller one, like the earthen pyramid shown in the foreground of the first image, would be a city improvement. The second one of Monk's Mound would be a small or great wonder.
Here is some information about Monk's Mound:
Monks Mound is the largest pyramid mound ever discovered in the United States. It is about twelve miles from Saint Louis, near the Mississippi river. The Cahokia site has 200 earthen mounds total. Monks Mound reaches a height of 30.5 meters. It covers 16 acres, with a north-south dimension of 316.1 meters, and an east-west dimension of 240.8 meters. Monks Mound has a total volume of approximately 21,690,000 cubic feet. Its base and total volume is greater than that of the pyramid of Khufu, the largest in Egypt. In all the world, only the pyramids at Cholula and Teotihuacan in central Mexico surpass the Cahokia pyramid in size and total volume. Atop the mound was a large temple where a priest/theocratic leader lived and conducted important ceremonies. In later Mississippian cultures this ruler was called the great sun and was believed to be the brother of the sun. The size and grandeur of the mound showed the power and status of the priest leader.
No other structure in the United States approached the size of the Cahokia pyramid until the building of airplane hangars, the Pentagon, and skyscrapers in the twentieth century.
