Later Lower Paleolithic Acheulian sites have been discovered in the highlands of Georgia, particularly in the caves of Kudaro (1600 m above sea level), and Tsona (2100 m). Acheulian open-air sites and find-spots are also known in other regions of Georgia, for example at the Javakheti Plateau where Acheulian handaxes were found at 2400 m above the sea level.
