Cerro del Topo Chico

Cerro del Topo Chico (literal English: Small Mole Hill) is an inactive volcano located in the western portion of the city of San Nicolás de los Garza and within the northern limits of the Monterrey metropolitan area (both cities are in the Mexican state of Nuevo León). The gray areas depicted on the photos are limestone quarries from which raw material is extracted to manufacture cement. Some other known mountains or elevations of the zone are: the Cerro de la Silla, Cerro de las Mitras, the Sierra Madre Oriental -the "m" figure visible from various parts of the city-, Cerro del Obispado, Cerro de la Loma Larga and La Huasteca.
