ID: 675
Other ID: GX-32726
Type: MicroSample
Subtype: pollen
Site: Caballete
Depositional context: midden

A pollen sample (Lab #194) collected from Operation II, Unit 1, Layer 13, Cuad E1 yielded 2 grains of maize pollen. A radiocarbon date was obtained on a sample of mixed plant fibers from the same layer, giving an indirect date for the pollen sample (Haas et al. 2013: Tables SI01 and SI02).
