Sierra Negra

Sierra Negra (left) and Pico de Orizaba (right)

The extinct volcano Sierra Negra (also called Tliltépetl ) is with its 4621 meters - after the Pico de Orizaba ( 5636 m), Popocatépetl ( 5426 m), the Iztaccihuatl ( 5230 m ) and the Nevado de Toluca ( 4680 m) - the fourth or fifth highest mountain in Mexico.

Location

The Sierra Negra (or Tliltépetl ) is only about 6 km ( straight line ) from the highest mountain in Mexico, Pico de Orizaba (or Pico de Orizaba ) away. Both mountains are located near the border of the Mexican state of Puebla to the eastern state of Veracruz within an established national park in 1937. The nearest city, Ciudad Serdán lies about 12 kilometers west.

Geology

For a long time remained the most non snowed mountain unnoticed, as he was considered a geologically connected to the Pico de Orizaba side peak. Only towards the end of the 20th century saw you the different geological structures of the two peaks. The Sierra Negra thus applies today as much older than the Pico de Orizaba.

Others

On the summit of Sierra Negra rises, completed in 2006 and operated by Mexican and U.S. universities Large Millimeter Telescope. Another solar telescope is already; the construction of other astronomical instruments is planned.
