The finds of chipped artefacts from Wetlina-Stare Sioło, Orłowicz Pass, Moczarne, and Czerteż Pass are the first archaeological confirmation of human activity in the Bieszczady mountains in the late neolithic. These finds correspond with older anthropological changes of vegetation recorded in pollen diagrams from smerek and Tarnawa wyżna which began ca. 2800 bc. They refer to the seasonal animal grazing in the high altitude landscapes. The use of high mountain pastures was connected with salt springs frequent in this area.
