Ancient Maize Map

Information

ID: 314
Other ID: AA-38769*
Type: MicroSample
Subtype: pollen
Site: San Andres
Depositional context: estuary

Pollen associated with an AMS-dated wood sample in core SAV4 at a depth of 993 cm below datum (Pope et al. 2001:1372).

*Note: This sample is listed as a duplicate AA-38768 in the column sequence in Pope et al. (2001:Table 1, p. 1372). Since it is bracketed by AA-38768 above it and AA-38770 below it, we assume this is a typographical error and the sample was accidentally mislabeled. AA numbers are uniquely assigned and so would not have two different dates.
