The construction of the 454-mile pipeline through the jungle and over the Andes to the coast has unearthed some 1,000 archeological sites from a range of civilizations across Peru that trace 9,000 years of history, archeologists say. The artifacts, which total 72 tons in weight, include mummies, textiles, jewelry, ceramics and weaponry that time and even the humidity of the jungle have been unable to destroy... One of the most exciting finds are the relics of the little-known Echarate culture, which lived some 3,300 years ago in today's Cuzco province
