Araracuara 3

Information

Site 3 is located near the Araracuara rapids along the middle Rio Caqueta, in the upper Amazon basin of southern Colombia (Herrera et al. 1992). It consists of about 14.5 ha of anthropogenic soils that average 40 cm in depth and have evidence of residential occupation, including dwelling remains and hearths, extending to a depth of 1 m below surface. Pollen cores from the site show the presence of maize beginning around the first century AD and continuing until ca. 1800. One radiocarbon sample gives a firm date of 1160+/-50 uncal BP (Beta-6950) (Herrera et al. 1992:102).
