Iztaccíhuatl (alternative spellings include Ixtaccíhuatl, or either variant spelled without the accent) ( or, as spelled with the x, ), is a dormant volcanic mountain in Mexico located on the border between the State of Mexico and Puebla. It is the nation's third highest, after Pico de Orizaba and Popocatépetl .
The name "Iztaccíhuatl" is Nahuatl for "White woman", reflecting the four individual snow-capped peaks which depict the head, chest, knees and feet of a sleeping female when seen from east or west.
Iztaccíhuatl lies to the north of Popocatépetl, to which it is connected by the high altitude Paso de Cortés. Depending on atmospheric conditions the dormant volcano is visible much of the year from Mexico City some to the northwest.
The first recorded ascent was made in 1889, though archaeological evidence suggests the Aztecs and previous cultures climbed it previously. It is the lowest peak containing permanent snow and glaciers in Mexico.
