El Coahuilón Mountain Range, Mexico
El Coahuilón, identifiable as a dark greenish-brown arch, is a mountain range located on the southeast side of the Mexican state of Coahuila, extending into Nuevo León.
The highest peak in the formation is about 3460 metres high. These mountains are part of the Sierra Madre Oriental, a system that runs from northeastern Mexico to the south side of the country.
As the dark green color suggests, the landscape on the slopes of El Coahuilón is forest with pine, fir and other evergreen tree species. Furthermore, this ecosystem has plenty of evergreen oaks and bushes.
Two cities are visible near the mountain range: Saltillo and Monterrey. Both can be identified as flat, tan patches amidst the darker, hillier surrounding terrain.
Saltillo (center) is the capital city of the state of Coahuila and the municipal seat of the municipality of the same name. The city is located 400km south of the Texas border, and 90km west of Monterrey.
Monterrey (northeast of Saltillo, above the arch of the mountain range) is the capital city of the state of Nuevo León. The city is ranked 2nd in terms of surface area in the country.
