Sikachi-Alyan is a small Nanai village at the Amur River downstream from Khabarovsk. Near this village you could see the famous petroglyphs aged from 3 to 13 thousand years. The pictures are carved on the boulders covering the river banks. Here you could see numerous human fases or masks, boats, and different animals including extinct ones. When we have visited this place there was high flood at the Amur; many petroglyphs were flooded.
Is it a shaman mask or a scull?
During the flood some of the stone faces can have a drink
