秘鲁Cotahuasi峡谷是世界上最深的峡谷,深度为3354米,是美国大峡谷的2倍左右深(Grand Canyon:1737米).美国最深的峡谷也不是大峡谷(Grand Canyon),而是地狱峡谷(Hells Canyon),深度为2436米.
 
Satellite image of southwestern Peru. The Pacific ocean is in the southwest corner of the mage but covered by a layer of white stratus clouds. Two deep canyons can be seen in the image. The eastern canyon was cut by the Rio Camana river and the western canyon was cut by the Rio Ocona. The large white area between these canyons is the snow-capped peak of Nudo Coropuna, a stratovolcano. At an elevation of 6617 meters it is the highest mountain in the Cordillera Occidental. The snowcap to the west is on Nevado Solimana, another stratovolcano at an elevation of 6117 meters. The main tributary of the Rio Ocona is the Rio Cotahuasi. The bottom of the Cotahuasi Canyon is 3354 meters below the top of the adjacent plateau. NASA Image
