Peru's President Alan Garcia arrives to the Inca citadel Machu Picchu in Cuzco, Peru on July 7. As the country prepares to celebrate the 100th anniversary of the rediscovery of the "Lost City of the Incas", archaeologists are warning that a heavy flow of visitors and poor administration are threatening one of the wonders of the world. The Incas built Machu Picchu atop an Andean peak with a breathtaking view across the inhospitable abysses that surround it.
