What AMS Radiocarbondating revealed

Site has Neolithic, Copper Age (aka Chalcolithic),
Early Bronze Age, and Late Bronze Age Components.
Therefore it is a multicomponent site.

Since there is so little soil, soil deflation might have
occurred.

The pottery are probably fragments of
Western Neolithic bowls.

Large flaked stone tools are probably the blades of
stone hoes, and date to the Late Bronze Age.
