The ancient mounds of Louisiana

Hundreds of ancient mounds are scattered all over Louisiana. The mounds keep clues—in the sorts of artifacts like projectile factors, pottery, axes, grinding stones, fired earth objects, and more—about the prehistoric cultures who lived there countless numbers of years back. I have unique recollections from childhood of browsing several of these mounds, which include these at the well-known Poverty Position Globe Heritage Web site (which is about 3,400 many years previous), as effectively as individuals on the campus of Louisiana State College. New research on the LSU mounds—which have been listed on the Countrywide Sign-up for Historic Destinations considering that 1999—has determined that they are the oldest identified guy-built buildings in the Americas. The Advocate clarifies:

According to a review led by LSU Division of Geology & Geophysics Professor Emeritus Brooks Ellwood, radiocarbon relationship suggests that construction of the very first mound commenced as early as 11,000 years in the past by historical Indigenous men and women.

The two grassy mounds, positioned alongside Dalrymple Drive, now stand about 20 ft tall and are two of the extra than 800 related male-manufactured mounds throughout Louisiana, most of which have been destroyed by time.

“There is absolutely nothing known that is guy-created and this outdated nonetheless in existence now in North The united states, except the mounds,” explained Ellwood, who led the examine just lately posted in the American Journal of Science by Yale University.

The new day on the mounds is not universally recognized, on the other hand. Chris Rodning, an anthropologist from Tulane College, expressed uncertainties about the accuracy of the new research. In accordance to The Advocate, having said that, Professor Ellwood isn’t bothered by the question:

He doesn’t take into consideration it an insult. “All people has their own perception and that’s reasonable, but we’ve invested 20 years working on these mounds, and this is not a trivial amount of money of time that we’re talking about,” he explained. “We’ve utilized a range of different techniques.”

If Ellwood’s radiocarbon dating is right, nevertheless, that’s really remarkable information. And if not, the LSU mounds—and the other folks that can be found all throughout the point out of Louisiana—are even now rather great. If you are at any time nearby, you must look at them out!
