Indian mounds

For our lab we visited the Ocmulgee Indian Mounds.  Ocmulgee National Monument preserves traces of over ten millennia of Southeastern Native American culture, including major earthworks built more than 1,000 years ago by Mississippian culture peoples: the Great Temple and other ceremonial mounds, a burial mound, and defensive trenches.One of the things we were able to learn about was the Great Temple Mound at Ocmulgee which was built atop the Macon Plateau and rises 56 feet high from the surface of the plateau.  Because the mound was constructed on the edge of the plateau, the mound rises 90 feet from the river bank below.
