A single season of field work was carried out in 1995 at the Podgoritsa Tell, an Eneolithic (5th millennium B.C.) settlement mound located between the villages of Dralfa and Podgoritsa in the Turgovishte region of NE Bulgaria. Results provide significant new data about the physical and social dimensions of early agricultural settlement tells in SE Europe. Most important is the first discovery of architectural structures and activity areas located outside of the topographic circumference of an Eneolithic tell. Additional, and equally unprecedented, information from geophysical and soil coring investigations proves that the land around the Podgoritsa site went through cycles of use and disuse. These cycles were determined by variations in the level of the local water table. Evidence of a bank and ditch structure on the western edge of the tell raises the possibility that the site's inhabitants may have been actively managing local water supplies. The firm evidence for off-tell activity (which explodes the myth that the modern visible topographic limits of a tell represent the limits of activity) and the possibility of 5th millennium hydrological engineering have important consequences not only for our understanding of the SE European Copper Age but also for future strategies of tell excavation across SE Europe and western Asia.
