By 2019 more than 70 sites had been discovered in the area of the High Bieszczady Mountains, most of them located within the Połonina Wetlińska massif. The sites discovered in 2017-2019 constitute two groups: sites represented by (1) single artefacts (Wetlina 56, 57, 58, 59, 61, 63, 64, 65, Bukowska Pass, site 1) and (2) small series of artefacts (Wetlina 54, 55, 60, 62). Both groups include artefacts datable to the Late Neolithic and the Bronze Age. Moreover, there are no sufficient grounds to claim homogeneity of assemblages found in Wetlina 54, 55, 60 and 62. It is possible that at least some of these sites could have been used many times during the Late Neolithic and Bronze Age periods. These finds confirm seasonal use of the High Bieszczady for grazing animals, probably within a system similar to the transhumant pastoralism practiced in European mountains.
