LSU Campus Mounds

The LSU Campus Mounds or LSU Indian Mounds are two Native American mounds, of the Archaic Period, on the campus of Louisiana State University in Baton Rouge, Louisiana. They are part of a larger, statewide system of mounds. They were probably used for "ceremonial and marking point purposes," rather than for burial purposes. The 20 feet (6.1 m) tall mounds are thought to be more than 5,000 years old. That date would make them part of the oldest mound system in North America, Mesoamerica or South America and also means they predate the building of the Great Pyramids of Egypt.

Location and history

The mounds overlook the floodplain of the Mississippi River. The northern mound consists of hard clay dirt; the southern mound is more porous. They were first dated in 1982. Due to their location in a heavily trafficked area of campus, the mounds gradually began to show signs of degradation as well as natural erosion. In order to alleviate the issue, the university installed a sidewalk between the mounds in 1985. In addition, a low brick wall was placed around the mounds in order to prevent vehicles from dangerously crossing the mounds. Unfortunately, erosion continued to take its toll until a restoration project was initiated in 1996. Using river silt, the LSU Facility Services patched damage on both mounds and seeded a hybrid Bermuda grass to prevent future problems. In 2009, LSU professor Brooks Ellwood took core samples that revealed a layer of charcoal, possibly from a pit barbecue or a cremation. Since 1999 they are listed on the National Register of Historic Places.
