Hidden in plain sight on the campus of Louisiana State University are two grassy hills that hold a secret 11,000 years old. These are the LSU Campus Mounds, now identified as the oldest known man-made structures in the Americas, predating both Stonehenge and the Egyptian Pyramids by millennia.
In an incredible feat of persistence, these mounds were built over a 5,000-year period by ancient indigenous people. Scientific analysis of soil cores has revealed layers of ceremonial ash and a sophisticated construction timeline that survived a dramatic prehistoric climate change. Most remarkably, the mounds were deliberately aligned with the rising of the red giant star Arcturus, marking their creators as some of the continent's first engineers and astronomers.
