Pico de Orizaba, also known as Citlaltépetl (from Nahuatl citlal(in) = star, and tepētl = mountain), is an active stratovolcano, the highest mountain in Mexico and the third highest in North America, after Denali of Alaska in the United States and Mount Logan of Canada. Pico de Orizaba is also the highest volcanic summit in North America. It rises above sea level in the eastern end of the Trans-Mexican Volcanic Belt, on the border between the states of Veracruz and Puebla. The volcano is currently dormant but not extinct, with the last eruption taking place during the 19th century. It is the second most prominent volcanic peak in the world after Africa's Mount Kilimanjaro. Pico de Orizaba overlooks the valley and city of Orizaba, from which it gets its Spanish name. During the colonial era, the volcano was also known as Cerro de San Andrés due to the nearby settlement of San Andrés Chalchicomula at its base. Its Náhuatl name, Citlaltépetl, comes from citlalli (star) and tepētl (mountain) and thus means "Star Mountain". This name is thought to be based on the fact that the snow-covered peak can be seen year round for hundreds of kilometers throughout the region. This name is not, however, used by Náhuatl speakers of the Orizaba area, who instead call it Istaktepetl (Iztactépetl in the traditional orthography for Classical Nahuatl), meaning 'White Mountain'. A third name, Poyauhtecatl, which means "the one that colours or illuminates", has also been recorded. This name was given by the Tlaxcaltecs in memory of their lost country. The peak of Citlaltépetl rises dramatically to an elevation of above sea level; it has a topographic prominence of . Regionally dominant, Pico de Orizaba is the highest peak in Mexico and the highest volcano in North America; it is also the third highest peak in North America after Denali and Mount Logan. Orizaba is ranked 7th in the world in topographic prominence. It is the second most prominent volcanic peak in the world after Africa's Mount Kilimanjaro, and the volcano is also ranked 16th in the world for topographic isolation.
