Wow, this looks interesting: archaeologists say they have discovered more than 50 geoglyphs of various shapes and sizes across northern Kazakhstan in Central Asia - a landscape reminiscent of the famous Nazca Lines in Peru:
Discovered using Google Earth, the geoglyphs are designed in a variety of geometric shapes, including squares, rings, crosses and swastikas (the swastika is a design that was used in ancient times). Ranging from 90 to 400 meters (295 to 1,312 feet) in diameter, some of them are longer than a modern-day aircraft carrier.
Over the past year, an archaeological expedition from Kazakhstan's Kostanay University, working in collaboration with Vilnius University in Lithuania, has been examining the geoglyphs. The team, which is conducting archaeological excavations, ground-penetrating radar surveys, aerial photography and dating, recently presented its initial results at the European Association of Archaeologists' annual meeting in Istanbul.
Many of the geoglyphs were made of earthen mounds, although one example, a swastika, was made using timber.
Archaeological excavations uncovered the remains of structures and hearths at the geoglyphs, suggesting that rituals took place there.
