Mexico's Big 7 - No 5

Sierra Negra (also, and perhaps more properly, called Cerro La Negra) is a companion peak of Mexico's highest mountain, the Pico de Orizaba. At 4,640 m (15,220 ft) above sea level (depending on which source one consults) it is one of Mexico's highest peaks, perhaps even the fourth highest. However, because it is overshadowed by its much higher companion it is not as well known as, for instance, the slightly lower Matlalcueitl, and is often not included in lists of Mexico's mountains.
The summit of Sierra Negra is the site for one of the world's premier astronomical instruments, the Large Millimeter Telescope. The service road for this project is claimed to be the highest road in North America. A part of the telescope facility is visible as a white dot in the first picture below and more clearly in the second picture.
