Cotahuasi Canyon (from Quechua Kutawasi), near the city of Arequipa in Peru, is one of the deepest canyons in the world. With a depth of approximately , it is more than twice as deep as the Grand Canyon. The Cotahuasi River eroded the canyon between two mountain massifs: the Coropuna ( ASL) and the Solimana ( ASL). It extends from spurs of the snow-covered Solimana to the confluence with the Ocoña River near the village of Chaucalla.
