CHAPTER Xn THE WESTERN ANDES: THE MARITIME CORDILLERAOR CORDILLERA OCCIDENTAL The Western or Maritime Cordillera of Peru forms part ofthe great volcanic field of South America which extends fromArgentina to Ecuador. On the walls of the Cotahuasi Canyon(Fig. 131), there are exposed over one hundred separate lavaflows pUed 7,000 feet deep. They overflowed a mountainous relief,completely burying a limestone range from 2,000 to 4,000 feethigh. Finally, upon the surface of the lava plateau new moun-tains were formed, a belt of volcanoes 5,000 feet (1,520 m.) highand from 15,000 to 20,000 feet (4,570 to 6,100 m.) above the we
