The relief of Coahuila, like most of the Mexican territory, is made up of a great variety of geographical features. To understand the relevance of these, its elevation with respect to sea level must be studied.
The fluctuations between its lower parts, which reach 200 meters above sea level (masl), and the Rio Bravo Valley with its 3715 masl, demonstrate its geological richness.
The action of the fallas in this territory created a variety of mountain ranges, hills, valleys and canyons that are scattered throughout the state. Likewise, there is a combination of large valleys and extensive plains between the north and south east.
The state of Coahuila is formed by the areas of the physiographic provinces of Sierras and Llanuras del Norte, which cover approximately 17%; the Sierra Madre Oriental, which covers approximately 65% and the Great Plains of North America, which take the remaining 18%.
This state is located in the central region of northern Mexico and limits geographically to the north with Texas in the United States, through the Rio Grande riverbed, to the west with Chihuahua, to the east with Nuevo León, to the southwest with Durango and towards the south with Zacatecas.
Division of Coahuila according to its geography
The relief of this state was divided into three zones or provinces according to their geographical location, which are detailed below:
-Zone Sierras y Llanuras del Norte: this area is made up of the folds as in the Sierra Mojada and del Rey that are at 2450 meters above sea level.
-Zone Sierra Madre Oriental: this area is made up of the El Burro, Santa Rosa, Menchaca and La Fragua mountains, which are 2120 meters above sea level, and the area between Parras de la Fuente and Saltillo.
-North American Great Plains Zone: it is made up of the folds that form the El Veterano and El Movimiento hills. There are also volcanoes and lava spills such as Agua Dulce, Kakanapo hill and El Barril hill.
Geographic division according to the highest peaks of Coahuila
A carving study on the dispersion and height of the various peaks in the area allows us to show the effects of the faults on the geography of this state:
1-Cerro San Rafael, which is located at 3,715 meters above sea level.
2-Cerro de la Martha, which is located at 3,680 meters above sea level.
3-Cerro el Coahuilón, which is located at 3,580 meters above sea level.
4-Pico del Penitente, which is located at 3,120 meters above sea level
5-Sierra la Madera, which is located at 3,010 meters above sea level.
6-Sierra de Parras, which is located at 2,860 meters above sea level.
Due to the variety of the relief, in this state we can find different types of temperature, which range from very high in desert areas, to snowy areas in its highest peaks.
Its climate varies between hot and dry, to extremely hot. This naturally affects the type of vegetation that we can find.
This state has four important areas declared as ecological reserves, which are distributed among different reliefs.
