Marsden Mounds (16 RI 3) is an archaeological site with components from the Poverty Point culture (1500 BCE) and the Troyville-Coles Creek period (400 to 1200 CE). It is located in Richland Parish, Louisiana, near Delhi.[1] It was added to the NRHP on August 4, 2004, as NRIS number 04000803.[2] It is the type site for the Marsden Phase (500-600 CE) of the Tensas Basin and Natchez Bluff regions local chronology.
The earthworks at the site include a group of five platform mounds and two portions of an earthen embankment. Mounds A, B, C and D (which are between 3feet and 5feet in height) are located along the eastern edge of Maçon Ridge with a section of the embankment connecting three of them. The largest mound at the site, Mound E, measures 13feet in height, with the base being 150feet by 150feet and a summit of 130feet by 130feet. It and another portion of embankment are located across a large plaza 300feet to the southwest of the other mounds.
During investigations at the site, artifacts from the Poverty Point culture were found under some of the mounds, showing that people occupied this at least as early as 1500 BC during the Archaic period. Radiocarbon dating of charcoal samples from one of the smaller mounds have been dated 400 and 1200 CE, during the Late Woodland Troyville-Coles Creek period.
The site is part of the Poverty Point Reservoir State Park. It is open to the public and accessible by foot.[1]
