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.
