Guilá Naquitz Cave is the westernmost of a group of six rockshelters that extend for about 600 m along the base of a 20-40 m high cliff overlooking a small valley that feeds into a small tributary of the Río Mitla (Kirkby et al. 1986:43-44). The archaeological site was discovered and excavated by Kent Flannery and his team in 1966 as part of a larger survey and test excavation project examining caves and rockshelters near Mitla in the Tlacolula arm of the Valley of Oaxaca (Flannery 1986:65). To date, this site has produced the earliest known, directly dated, maize macroremains (Piperno and Flannery 2001).
