The elongate Iztaccíhuatl has a more conical profile when viewed from the Querentano hut on Popocatépetl to the south. One of the youngest vents of Iztaccíhuatl produced a lava flow north of the Paso de Cortés saddle between the two volcanoes. The flow traveled 5 km to the east.

Popocatépetl volcano is seen here to the south from the Iztaccíhuatl summit ridge. Unlike the eroded Iztaccíhuatl volcano, which has been infrequently active during the Holocene, Popocatépetl has been vigorously active.

The northern end of the Iztaccíhuatl summit ridge is seen here from east of the Paso de Cortés to the south. A postglacial vent is located on the lower south flank of the volcano, north of the saddle between Iztaccíhuatl and Popocatépetl.

Iztaccíhuatl along with Popocatépetl are the subjects of legends with their morphologies reflecting their characters. The profile of a sleeping woman can be seen here from the west above the Valley of Mexico. A series of overlapping cones constructed along a NNW-SSE trend forms the summit ridge. From left to right they are La Cabeza (the head), El Pecho, Las Rodillas, and Los Pies (the feet). The volcano is mostly Pleistocene in age, but minor Holocene activity has occurred.

Iztaccíhuatl rises SW of the Puebla basin in central México. A series of overlapping cones constructed along a NNW-SSE trend forms the summit ridge, which is 6 km long just above the snowline. Glaciation has extensively eroded the summit and flanks of the dominantly Pleistocene edifice. The Toltec climbed Iztaccíhuatl and left terracotta, carved stone, jade, and obsidian artifacts just below the summit, forming the highest archeological site in North America.

Iztaccíhuatl (left) and Popocatépetl (right) seen east of the Valley of Mexico. The differing profiles of the two volcanoes are due to varying styles and durations of volcanism. Iztaccíhuatl's elongate form reflects migration of volcanism over long periods of time along a NNW-SSE trend; it is largely Pleistocene in age, and has been extensively eroded. The more symmetrical Popocatépetl is much younger and has more-localized vents.

The Sierra Nevada east of the Valley of Mexico is a N-S-trending volcanic chain that runs perpendicular to the E-W trend of the Mexican Volcanic Belt. As with other transverse volcanic chains such as Cántaro-Colima and Cofre de Perote-Orizaba, the volcanic features in the Sierra Nevada range are younger towards the south. The broad forested volcanoes of Tláloc and Telapon in the distance are Pliocene in age, Iztaccíhuatl in the center is largely Pleistocene, and Popocatépetl in the foreground has been historically active.

Iztaccíhuatl rises more than 2.5 km from the floor of the Valley of Mexico to form one of Mexico’s highest volcanoes. The profile of a sleeping woman in the legend of Popocatépetl and Iztaccíhuatl can be seen in this view from the west. The massive 450 km3 volcano is a composite of overlapping edifices along a N-S-trending line.

Iztaccíhuatl (right) and Popocatépetl (left) rise above farmlands at the eastern margin of the Puebla basin within Izta-Popocatépetl National Park. Andesite and dacite lava flows erupted from vents along the N-S-trending summit ridge of Iztaccíhuatl extend all the way to the base of the volcano. A small plume rises from the summit of Popocatépetl in this 1996 photo.

Iztaccíhuatl and Popocatépetl are part of the N-S-trending Sierra Nevada range SE of Mexico City. Iztaccíhuatl, in the center of the range, is to the upper left, and Popocatépetl is in the foreground at the southern extremity of the range. The Sierra Nevada separates the Valley of Mexico from the Puebla basin, which can be seen to the east. Ashfall from recent eruptions covers the summit snow cover this 1996 photo.

Iztaccíhuatl is a massive 450 km3 stratovolcano SE of Mexico City, seen here from the SW. The summit is composed of several overlapping edifices, including the northernmost peak, La Cabeza (left), the snow-capped high point El Pecho, and Las Rodillas (below the lower Ayoloco glacier near the center). Most activity ceased during the Pleistocene, and the volcano has been extensively glaciated, as seen by the sharp-crested glacial moraines below the Ayoloco glacier.

The profile of Iztaccíhuatl seen from the summit of Papayo volcano to the north. The northern base of the volcano is the Llano Grande edifice (the oldest edifice of Iztaccíhuatl) and the NW-flank La Trampa lava flows. The low-angle ridge extending to the NE (left) consists of the Teyotl dacite lava flows that erupted from a vent on the upper northern flank about 80,000 years ago. A gas plume can be seen at the summit of Popocatépetl to the far right.

The broad Iztaccíhuatl massif rises north of Paso de Cortes, the saddle between Iztaccíhuatl and Popocatépetl volcanoes. The summit of Iztaccíhuatl is at the left, NNW of the apparent high point Las Rodillas (center). The sharp peak at the right is Los Pies (also known as Amacuilecatl), the southernmost major peak of the volcano.

The volcanoes bordering the Valley of Mexico appear in Aztec legend. Popocatépetl (right) is said to hold a funeral torch for Iztaccíhuatl (left), the sleeping "Woman in White." The hills in the foreground (seen from the summit of Xitle scoria cone) are part of the broad Chichinautzin volcanic field south of Mexico City. Chichinautzin means "Burning Lord," a possible reference to eruptive activity.

Photo by Lee Siebert, 1997 (Smithsonian Institution).
Monogenetic cones of the Chichinautzin volcanic field are seen here below the western flanks of Iztaccíhuatl. These cones, including Cerro Tenayo to the lower left, lie at the easternmost extension of the 90-km-wide Chichinautzin volcanic field, south of the Valley of Mexico. The compound Iztaccíhuatl volcano is mostly Pleistocene in age.

Iztaccíhuatl rises above the clouds in this aerial view from the NW. The summit ridge is formed by a series of overlapping edifices. La Cabeza is to the left, glacier-covered El Pecho in the center, and Las Rodillas to the far right.

A view from a helicopter heading east towards Popocatépetl (right) and Iztaccíhuatl (left) in March 2000 during a monitoring flight. Opposing winds above 6 km give the gas plume from Popocatépetl an "S" shape. The Centro Nacional de Prevención de Desastres (CENAPRED) is engaged in an active monitoring program on Popocatépetl using instrumentation to evaluate seismic, geodetic, and geochemical parameters of the ongoing eruption.

The N-S-trending Popocatépetl-Iztaccíhuatl volcanic chain lies between the Valley of Mexico and the Puebla basin. Snow-capped Iztaccíhuatl volcano lies just above the center of the image. The city of Texmelucan can be seen at the upper right. Across the Paso de Cortés from Iztaccíhuatl is steaming Popocatépetl volcano, located SE of the city of Amecameca (mid-left margin). A voluminous prehistorical lava field from Popocatépetl forms the forested lobe extending about 20 km down the eastern flank at the lower right.

An ash plume from Popocatépetl reaching over 9 km above sea level and dispersing to the south on 23 January 2001. Larger explosions the day before had produced plumes that rose 8 km above the summit and pyroclastic flows that traveled 4-6 km down the north flank. The large dark-colored area below and to the left of the volcano is a lava field. The elongate Iztaccíhuatl volcano is visible to the lower right.

Iztaccíhuatl (left) and Popocatepetl (right), two of the highest volcanoes in Mexico, are seen from the SW on a rare smog-free day. The morphology of Iztaccíhuatl is due to multiple vents across the summit region . Fresh snowfall at Popocatepetl covers periodic ashfall deposits.

This photo looks south from Telapón volcano and shows the rounded Papayo lava dome in the foreground, with snow-capped Iztaccíhuatl (left) and Popocatépetl (right) in the background. These volcanoes, along with Telapón, and Tláloc stratovolcanoes, form a N-S-trending chain east of Mexico City and transverse to the Mexican Volcanic Belt trend.
