In spite of numerous conjectural attempts to prove or disprove the existence of historical continuity between contemporary and prehistoric pastoral transhumance, the evidence for specialized pastoralism has yet to be found in the archaeological record. The ethnoarchaeological survey of contemporary pastoral sites in the Grevena Prefecture of Greek Macedonia is a first step toward developing a diachronic model for the pastoral exploitation of upland areas in the eastern Pindos Mountains. The survey transect crosscuts two environmental zones of the eastern flank of the Pindos Mountains, ranging from 840 to 1540 m in elevation and including a total of 87 modern pastoral sites. Ethnographic information includes data on animal husbandry practices, mobility strategies, and length of site occupation among Koutsovlach and other pastoralists from the Grevena region. Archaeological data include site locational variables, site contents (architecture, artifacts, and ecofacts), and attributes associated with site visibility and abandonment processes at pastoral encampments.
