The Yuhualixqui Volcano is one of the monogenetic volcanos of the Sierra de Santa Catarina chain of mountains. This one is entirely within Iztapalapa. Most of the chain forms part of the border between Iztapalapa and Tláhuac to the southeast.
The Nahuatl name, Yuhualixqui, translates roughly to “that which overshadows” or “place where shade is given.” The mountain also is referred, though rarely today, as the Alvarado Mountain or the San Nicolas Volcano.
The peak rises to some 2,420 meters above sea level. It’s one of the most overexploited and deteriorated parts of the Sierra. A private mining company actually purchased the mountain about 40 years ago. The overall body has been reduced by about 60%. It was also badly shaken by the earthquake of September 19, 2017 which caused a significant landslide and further deterioration.
The mountain is a daily part of life in San Lorenzo Tezonco. It’s been celebrated here for generations. Residents and activists have protested for many years to halt ongoing extractions. The peak is a major source of captured groundwater in the area. It’s also a habitat for local rabbits and hares.
It’s about 2.4 kms from the nearest peak of Xaltepec.
