The copper canyons are located in the heart of the Sierra Madre Occidental in northwestern Mexico. The canyon rim is at an average altitude of 2,400 m, where the surrounding peaks reach heights of up to 3,300 meters. The complete canyon system is composed of six main canyons (Cobre, Urique, Sinforosa, Huápoca, Batopilas, and Otero-Candamena Chínipas), of which each individual digs deeper into the volcanic rock of the Sierra Madre as the Grand Canyon of the Colorado River. Barranca Urique reaches a depth of 1.879 m. The main streams of the gorge flow towards the Pacific, while inflows to these main veins are parallel to the coast. The canyons of the Sierra Madre were formed from a thick block of rock of volcanic origin during the Tertiary Period (about 45 million years ago). Further eruptions (andesine and rhyolite) created in conjunction with the natural erosion in the Pleistocene period the current canyon landscape. Through continuous mineralization evolved over millions of years the famous gold, silver and copper deposits in the canyons. The Copper Canyons are the largest contiguous canyon system in the world and are breathtaking in every way.
