Petroglyphs in Chukotka

The expedition of the Institute of Archaeology of the Russian Academy of Sciences has finished this years' work on river Pegtymel in Chukotka. About 40 years ago, 103 petroglyphs were found there by geologist Samorukov. Since then, the drawings remain the only example of rock painting in north-eastern Siberia. The dating of the petroglyphs is still unclear. Expeditions often visit the area in the last years. Two years ago, about 170 new drawings were found and in this year some more were discovered. Some of them are damaged by severe weather conditions and now the questions of conservation are discussed.
