Sierra Madre Occidental The Sierra Madre Occidental is a major mountain range system of the North American Cordillera, that runs northwestâ€“southeast through Northwestern and Western Mexico, and along the Gulf of California. The Sierra Madre is part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, South America and Antarctica.
Sierra Madre Occidental Railroads came to the area starting in the 1880s and 1890s, which allowed many old mines in the region to reopen at a profit.[119] Since most of the railroads were American, the foreign influence led to unrest among the people living in the mountains, causing the Tomochic rebellion in 1892.[120] In addition to the railroads, canals were constructed in the 1890s in the Yaqui and Mayo river valleys.[121] However, these canal projects failed due to the resistance that the natives of the valleys put up against the projects.[122] Loggers began arriving in the mountains in the late 1800s. In response to the new industry, the Tarahumara moved further into the canyons.[119]
Sierra Nevada (U.S.) The Sierra Nevada (/siˌɛrə nɪˈvædə, -ˈvɑːdə/, Spanish: [ˈsjera neˈβaða], snowy saw range[6]) is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, a chain of mountain ranges that consists of an almost continuous sequence of such ranges that form the western "backbone" of North America, Central America, South America and Antarctica.
Geography of Mexico The Sierra Madre Oriental mountain range starts at the Big Bend region of the border with the U.S. state of Texas and continues 1,350 kilometres (840 mi) until reaching Cofre de Perote, one of the major peaks of the Cordillera Neovolcánica. As is the case with the Sierra Madre Occidental, the Sierra Madre Oriental comes progressively closer to the coastline as it approaches its southern terminus, reaching to within 75 kilometres (47 mi) of the Gulf of Mexico. The northeast coastal plain extends from the eastern slope of the Sierra Madre Oriental to the Gulf of Mexico. The median elevation of the Sierra Madre Oriental is 2,200 metres (7,200 ft), with some peaks at 3,000 metres (9,800 ft).
