The Sierra Madre Occidental is a mountain range located in northwestern Mexico, running parallel to the Pacific coast. It extends approximately 700 miles (1,100 km) from north to south and serves as the western border of the Mexican Plateau.12
To its west, the range is bounded by the Pacific Coastal Lowlands, while its eastern side flanks the inland plateau. The region is characterized by its volcanic composition and is highly incised by westward-flowing streams that have carved out deep gorges known as barrancas, including the famous Copper Canyon in the state of Chihuahua.23
