T he earliest site, Adam Buthi , dates to the 4th millennium, but the early 3rd millennium BC was a period of growth in terms of number and size of settlements.
Many sites appear to be associated with dams.
T he pattern is very similar during the later 3rd millennium, but then occupation was either restricted to a small area of an earlier site, or sites were newly founded. T he presence of quite a number of town-like settlements added a new and unexpected dimension to this cultural complex and to an area which sofar had remained in the shadow of the Indus Civilization. These new and exciting findings require a rethinking of models of interaction and center-periphery relations between these two areas. In southeastern Balochistan, however, the settlements and irrigation systems were abandoned. No sites dating to the subsequent centuries were found.
