Ancient Technology in Peru and Bolivia

┬╖Fully illustrated thoughout with photos and diagrams┬╖Examines ancient sites in South America and reveals evidence that they were made by a far older culture than originally thought┬╖Reveals evidence that the technology used could only have been ''power'' toolsIn his new book, packed with photos and diagrams, Childress examines the amazing stone cutting at Puma Punku near the ancient ruins of Tiwanaku near Lake Titicaca in Bolivia. He looks at whether the so-called "Inca walls" were really made by the Incas. The evidence seems to support the idea that they were actually constructed by a far older culture. Childress examines the megalithic construction and underground chambers of Chavin in Peru; he speculates on the existence of a sunken city in Lake Titicaca and reveals new evidence that the Sumerians may have arrived in South America over 4,000 years ago. Childress demonstrates that the use of "keystone cuts" with metal clamps poured into them to secure megalithic construction was an advanced technology used all over the world, from the Andes to Egypt, Greece and Southeast Asia. He maintains that only power tools could have made the intricate articulation and drill holes found in extremely hard granite and that the megalith builders had to have had advanced methods for moving and stacking gigantic blocks of stone, some weighing over 100 tons. The incredible high-tech world of South America is illuminated in the informative and breezy style that Childress has been known for in his books and his appearances on television shows like Ancient Aliens.
