Cypress Grove is one of the best-preserved conical mounds in northeast Louisiana. It’s near a lake that used to be part of the Tensas River. The mound measures about 10 feet high and 115 feet in diameter at its base. A small pond about 60 feet north of the mound may be a borrow pit where soil was removed for mound construction. Two cores from the mound show that it was built in one stage over a thick midden (accumulated debris from previous occupants). Radiocarbon dating of organic material from beneath the mound suggests that the mound was built about AD 750, during the late Troyville or early Coles Creek periods. Few artifacts have been recovered from the site and its immediate surroundings, which is unusual. It is said that there are two historic burials in the mound.
