Petroglyphs are rock carvings. The oldest is 12 thousand years old BC. There is a legend about the origin of petroglyphs. The oldest images are about 12 thousand years old, and the "youngest" ones are about 3 thousand years old — that is, they appeared much earlier than the Egyptian pyramids.

It is their strong, skillful hand that has carved images of moose, birds, boats and snakes on Sikachi - Alyan basalts, as well as many mysterious disguises. These are not primitive petroglyphs, but the works of masters of the school of stone cutters of later centuries.
