The Cuautzin lava dome (right horizon) north of the crest of the Sierra Chichinautzin, with cnow-capped Iztaccihuatl volcano on the left horizon. It formed between about 7,360 and 8,225 radiocarbon years ago, producing lava flows and block-and-ash flow deposits around the dome. Cuautzin means "Seat of the Eagle" in the Nahuatl language.
