Altzomoni is a volcanic peak located in the State of Mexico. Situated between the volcanoes Popocatépetl and Ixtaccíhuatl in the northern portion of the Paso de Cortés, Altzomoni rises 4,200 metres (13,800 ft) above sea level. It is located inside Izta-Popo Zoquiapan National Park.
The area is used as a base for those climbing Ixtaccíhuatl. It also is recognizable for its large television tower, used by Televisa for the transmission of analog television to Puebla and Cuernavaca.
The Universidad Nacional Autónoma de México also maintains an atmospheric observatory on the mountain.[1]
