The Nazca Lines are a collection of unusual, large ancient geoglyphs etched into the high plateaus of the Nazca Desert in southern Peru. The largest are nearly a quarter-mile long and depict a variety of objects and shapes including more than 70 drawings of animals such as birds, fish, llamas, jaguars, and monkeys – many of which would have been unknown to inhabitants of the area. Some depict human-like entities. They cover an area about 170 square miles and are only visible from the air. The drawings are believed to have been created sometime between 500 BC and 500 AD. They were made by gouging shallow lines about 6-inches deep into the ground, removing the natural iron oxide-coated reddish pebbles and exposing the grayish ground beneath.
The Steppe Geoglyphs of Kazakhstan Using space imagery, NASA scientists have discovered hundreds of strange geoglyphs, including a swastika and perfectly-formed cross, etched across a barren savanna in Kazakhstan. Satellite photos taken over 400 miles above the earth’s surface first revealed the enigmatic objects, now known as the Steppe Geoglyphs, to a Kazakh economist (Dmitriy Dey) in 2007. His accidental discovery led to more in-depth scientific study of their mysterious origins and curious meaning. The myriad of unusual patterns are believed to be at least 8,000 years old which would make them the oldest creations ever found. Thus far, researchers have been unable to decipher the meaning of the ancient symbols. Almost all of the symbols, which are unrecognizable from the ground, are formed from mounds of dirt about
