Iztaccíhuatl , is a dormant volcanic mountain in Mexico located on the border between the State of Mexico and Puebla within Izta-Popo Zoquiapan National Park. It is the nation's third highest, after Pico de Orizaba at, and Popocatépetl at. 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 is to the north of its twin Popocatépetl, to which it is connected by the high altitudePaso de Cortés. Depending on atmospheric conditions Iztaccíhuatl 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.
Geology
The summit ridge of the massive volcano is a series of overlapping cones constructed along a NNW-SSE line to the south of the PleistoceneLlano Grandecaldera. There have been andesitic and dacitic Pleistocene and Holocene eruptions from vents at or near the summit. Areas near the El Pecho summit vent are covered in flows and tuff beds post-dating glaciation, approximately 11,000 years ago. The most recent vents are at El Pecho and a depression at along the summit ridge midway between El Pecho and Los Pies.
In Aztec mythology, Iztaccíhuatl was a princess who fell in love with one of her father's warriors, Popocatépetl. The emperor sent Popocatépetl to war in Oaxaca, promising him Iztaccíhuatl as his wife when he returned. Iztaccíhuatl was falsely told that Popocatépetl had died in battle, and believing the news, she died of grief. When Popocatépetl returned to find his love dead, he took her body to a spot outside Tenochtitlan and kneeled by her grave. The gods covered them with snow and changed them into mountains. Iztaccíhuatl's mountain is called "White Woman" because it resembles a woman lying on her back, and is often covered with snow — the peak is sometimes nicknamed La Mujer Dormida, "The Sleeping Woman". Popocatépetl became an active volcano, raining fire on Earth in blind rage at the loss of his beloved.
