The largely volcanic Sierra Madre Occidental , which forms the western border of the Mexican Plateau, has an average elevation of 8,000–9,000 feet (2,400–2,700 metres) and extends roughly 700 miles (1,100 km) from north to south. It has been highly incised by westward-flowing streams that have formed a series of gorges, or barrancas , the most spectacular of which is the complex known as Copper Canyon (Barranca del Cobre) in southwestern Chihuahua state.

Often considered an extension of the Rocky Mountains (which are cut by the Rio Grande but continue in New Mexico and western Texas), it runs roughly 700 miles (1,100 km) from north to south before merging with the Cordillera Neo- Volcánica. Its average elevations are similar to those of the Sierra Madre Occidental, but some peaks rise above 12,000 feet (3,650 metres). The mountains have major deposits of copper, lead, and zinc. The Cordillera Neo-Volcánica , also called the Neo-Volcanic Axis or Trans-Volcanic Axis, is a geologically active mountain range whose smoldering cinder cones link the Sierra Madre Occidental with the Sierra Madre Oriental at the southern edge of the Mesa Central.

This volcanic range includes the spectacular peaks Citlaltépetl, Popocatépetl, and Iztaccíhuatl (Ixtacihuatl), among others. One of the world’s youngest volcanoes, Parícutin emerged violently from the fields of Michoacán between 1943 and 1952. The region is rich in silver, lead, zinc, copper, and tin deposits. The hot, dry Balsas Depression, which takes its name from the major river draining the region, is immediately south of the Cordillera Neo-Volcánica. The depression is formed of small, irregular basins interrupted by hilly outcrops, which give the area a distinctive physical landscape.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
