Peru's vast Colca Canyon in Arequipa, south of Lima, the world's second deepest gorge that gives birth to the mighty Amazon River, has the Andean nation hoping it can kindle its nascent tourism industry. The Canyon, which plunges to depths of 11,110 feet and stretches more than 60 miles in the volcanic highlands of Peru, draws tourists from around the world to visit not only its vast terraced slopes but to catch a glimpse of the soaring condors that make it their home.
