The Atacama Giant is an anthropomorphic geoglyph on the Cerro Unitas area of the Atacama Desert, Chile. At about 119 meters, is the largest prehistoric anthropomorphic geoglyph. It has been suggested that the petroglyph represents a shaman, spiritual figure or deity, but there is little evidence to corroborate these claims. The figure was an early astronomical calendar for knowing where the moon would set; by knowing this the day, crop cycle, and season could be determined.
