Dating the finds from the "Court of the Pile Dwellers" has been a problem. Because of the limited knowledge of the archaeological discipline at the time, no record of the stratification of the objects was kept. They cannot be placed in sequence. There is no sign of European trade goods or influence in the finds. Radiocarbon dating did not exist at the time of excavation. Radiocarbon dating of objects which have been handled and stored away from their original environment for long periods may not be reliable. In the 1960s an attempt to radiocarbon date some objects yielded a date of 1670 AD. A second attempt in 1975 using five different objects yielded dates from 55 AD to 850 AD.
