Join us for Saturday Science, LSU's free public talk series connecting the community to science and technology. This month Dr. Brooks Ellwood will speak on the LSU Campus Mounds: Oldest man-made structures in the Americas.

Radiocarbon dating of the two LSU Campus Mounds indicates that they are probably the oldest known and intact manmade structure in the Americas. The older (deeper) parts of both of the LSU Campus Mounds contain many thin, burned ash lenses, suggesting that the Mounds may have been used for ceremonial or cremation purposes. In this talk a detailed analysis of the mounds and estimates on their age will be discussed.
