Sierra madre occidental location

It is in Mexico. The Sierra Madre Occidental is about miles long km. It runs along the Gulf of California. These mountains have deserts nearer to sea level and oak forests further up.

The Sierra Madre Occidental is a major mountain range system of the North American Cordillera , that runs northwest—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 consist of an almost continuous sequence that form the western "sounds" of North America , Central America , South America , and West Antarctica. The Spanish name sierra madre means "mother mountain range" in English, and occidental means "western", these thus being the "Western mother mountain range". The range extends from northern Sonora , a state near the Mexico—U. The high plateau that is formed by the range is cut by deep river valleys. This plateau is formed from volcanic rock overlying a basement of metamorphic rock. This uplift has caused changes in weather patterns; increased rainfall occurring in the mountains has provided areas where ecosystems can form in wetter areas than surrounding land.

The Sierra Madre Occidental is a series of mountains in the North American Cordillera running northwest to southeast through western and northwestern Mexico and along the Gulf of California. This mountain range system is also part of the America Cordillera, a mountain range system consisting of an uninterrupted sequence of mountain ranges forming the western backbone of West Antarctica, North, Central, and South America. The mountain range forms a high plateau that is mainly cut by the deep river valley. This region has a dramatic landscape consisting of steep mountains that have been formed by a high plateau cut through by canyons such as the Copper Canyon. The high plateau is approximately 7, feet. The highest elevation of the Sierra Madre Occidental occurs in the Tarahumara Range although the precise elevation of the highest peak is not accurately known. The highest elevation is probably Cerro Mohinora, estimated to be approximately 9, feet and may go up to 10, feet. Cerro Barajas is also thought to be the highest at 10,, feet. The climate of the mountain range varies significantly between its northern and southern extents. The seasonal variations are as a result of the large, warm water bodies that deliver warm damp air from each side of the range. The region experiences two wet seasons and two dry seasons every year. The change of air pressure in northwestern Mexico and the southwest US is considered the major cause of seasonal variation.

The EBA is characterized by temperate forests: with increasing altitude from 1, to 3, m these are of mature pine oak, pine, and fir. The dominant species are mainly pine Pinus but also spruce Abies , firs Pseudotsuga , oaks Quercus , Arbutus and Pop ulus. In humid canyons below 2, m the main habitat is evergreen and semi-evergreen forest. All the restricted-range species are forest birds, apart from Xenospiza baileyi , which favours marsh and bunch-grass, but is normally in areas with some pines. This species and Atlapetes virenticeps are found in both the Sierra Madre Occidental and the trans-Mexican range, whereas Rhynchopsitta pachyrhyn cha but see below , Campephilus imperialis and Cyanocorax dickeyi are mainly in the Sierra Madre Occidental, with C. Eared Quetzal Euptilotis neoxenus is not included as a restricted-range species though, like Rhyncho psitta pachyrhyncha and Campephilus imperialis , it is confined to the Sierra Madre Occidental because its habitat and altitudinal preferences are more varied than these species and it is therefore judged to have a range larger than 50, km 2. Campephilus imperialis shows the most precise preferences, being a specialist of old-growth pine forests trees commonly m to the lowest limb with many dead branches, usually intermixed with grassy areas on flat mountain-tops, and with almost all records coming from 1,, m Collar et al.

The Sierra Madre is the principal mountain system of Mexico that encloses the central Mexican Plateau. Extending the length of Mexico, the mountains form a broad northwest-southeast arc. The Sierra Madre mountain system is part of the American Cordillera, a chain of mountain ranges cordillera that consists of an almost continuous sequence of ridges that form the western backbone of North America, Central America, South America, and West Antarctica. The primarily volcanic Sierra Madre Occidental is a primary mountain range system of the North American Cordillera that runs 1, km mi on a northwest-southeast course parallel to the Pacific coast of Mexico; through northwestern and western Mexico and along the Gulf of California. Forming the western border of the Mexican Plateau , the range extends from northern Sonora state near the Mexico-U. Deep river valleys, or barrancas, cut the high plateau formed by the range, the most spectacular of which is the complex known as Copper Canyon Barranca del Cobre in southwestern Chihuahua state. This plateau is formed from volcanic rock overlying a basement of metamorphic rock. This uplift has caused changes in weather patterns; increased mountain rainfall has provided areas where ecosystems can form in wetter areas than the surrounding land. This water source creates watersheds that feed the arid surroundings with water, making it possible to irrigate and farm crops. The wet ecosystems are islands of biodiversity, differing significantly from what would otherwise be a desert landscape.

Running from north to south along the western coast of Mexico , the Sierra Madre Occidental is a chain of peaks known for its rugged summits and deep canyons, or barrancas. The Sierra Madre Occidental is a massive system of mountain ranges that runs down the west coast of Mexico. It is bordered to the north by the Southwest Basins and Ranges which themselves are a subsection of the Great Basin Ranges. Meanwhile, to the east, the range transitions into the Mexican Plateau. Overall, the Sierra Madre Occidental is a very remote region of Mexico.

Numerous small populations live in Copper Canyon, some of them around old missions. Summer temperatures maintain a constant level. Bibcode : EcGeo.. Perhaps one of the first Europeans to arrive in the region was Francisco de Ibarra,who traveled along the western coast of Mexico and crossed the Sierra Madre in the s and s.

In addition to increasing in the southern ranges of the mountains, rainfall increases in the higher elevations of the Sierra Madre Occidental. Tools Tools. Pinal Peak. Mica Mountain Rincon Peak. Campephilus imperialis shows the most precise preferences, being a specialist of old-growth pine forests trees commonly m to the lowest limb with many dead branches, usually intermixed with grassy areas on flat mountain-tops, and with almost all records coming from 1,, m Collar et al. The mountains are home to several indigenous nations speaking Uto-Aztecan languages , including the Tarahumara in the central portion of the range, the Huichol in the southern part of the range, and the Tepehuanes in the eastern slopes. The Sierra Madre Occidental pine-oak forests are found at elevations of 1,—3, m 4,—9, ft throughout the range, [76] but the forests in the mountains vary by elevation and place in the range.
