single conical mound at Lamarque sits on a natural levee of the
Tensas River. It’s one of six such solitary mound sites
(five with markers) along the river, and is about 6 feet tall
and 115 feet in diameter. Highway construction in 1956 cut through
the mound and exposed three stages of mound construction. The
mound is about 75% intact today. Pottery pieces exposed by plowing
near the mound date to about AD 1000 (Coles Creek/Plaquemine periods).
Some of those artifacts were at a depth of 3 feet, leading archaeologists
to believe there is a buried living surface near the mound. A
small historic cemetery is on the west side of the site.
