Sierra madre occidental location

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 sierra madre occidental location of mountain ranges forming the western backbone of West Antarctica, North, Central, sierra madre occidental location, and South America. The mountain range forms a high plateau that is mainly cut by the deep river valley.

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.

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. This water source forms watersheds that provide the arid surroundings with water that makes it possible to irrigate and farm crops. The wet ecosystems are islands of biodiversity, differing significantly from what would otherwise be a desert landscape. Oak forests are the predominant plant life, and extend into the lowland deserts. This forest and canyon land provided a place for a variety of indigenous people to live, until Spanish settlers with associated mestizos came into the area to found towns for the silver mines in the area. The major industries in the area now are agriculture and forestry, which have become contentious because of land degradation and the native population's opposition to these practices. The range trends from the north to southeast. Canyons cut by the rivers of the wet western slopes exist in addition to those of the northeast slopes, notably the Copper Canyon. Sierra Tarahumara or Tarahumara is the name for the region of the Sierra Madre beginning at the Durango border and extending north.

Tarahumara moved further into the mountains in order to escape the conditions. Monsoon season is the largest of these effects, with leaf buds following only a few months after the rains begin.

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.

October 28, JPEG. Stretching about 1, kilometers miles , the Sierra Madre Oriental is a range of folded mountains in northeastern Mexico. Formed about 60 million years ago, the mountains are composed of limestone and shale and contain major deposits of copper, lead, and zinc. Some peaks rise more than 3, meters 12, feet. The image above shows the rugged folds and valleys of the Sierra Madre Oriental.

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.
