Ancient Maize Map

Information

ID: 680
Other ID: AA-95571
Type: MicroSample
Subtype: pollen
Site: Caballete
Depositional context: feature

A pollen sample (Lab #687) collected from Operation V, Unit 19, Cuads Q13-S13, Feature 65, yielded 17 grains of maize pollen. A radiocarbon date was obtained on a sample of plant fiber from Feature 110 in the same Cuadrants, giving an closely associated indirect date for the pollen sample (Haas et al. 2013: Tables SI01 and SI02).
