Russian geoglyph

This mysterious geoglyph, depicting an elk or a moose, was found on slopes of the Zyuratkul Mountains in the Chelyabinsk region in Russia and might be the oldest geoglyph yet discovered. Stone tools found alongside the feature have been dated to the Neolithic or Chalcolithic periods between 4000 and 2000 B.C. It's therefore possible that it was constructed by an ancient "megalithic culture," researchers have said.
