Loma Alta

Information

This is one of the earliest Valdivia culture sites and is located in the Valdivia River Valley, approximately 9 km inland from the Pacific coast. The remains of house floors, pits, middens, and burials occur in deposits up to 1.5 m deep (Damp 1984a). Few maize macroremains have been recovered from this site, but microremains (phytoliths and starch grains) are abundant (Zarrillo et al. 2008; Damp 1984b).
