Historical Marker

Indian Mounds

Baton Rouge, East Baton Rouge County · Louisiana

How old are they? The signs say about 6,000 years, another says 5,000, and a 2022 paper in the American Journal of Science by Brooks Ellwood and others argues construction began more than 11,000 years ago, possibly 11,300. Ellwood's 2009 cores found a charcoal layer. For years the mounds were tailgate ground; since 2010 they have been fenced during home football games. LSU manages the site, which is on the National Register, and visitors are asked to stay off. No source here names the builders' nation.
