Also, the flow from all of the remaining strong springs in the area adjacent to the peak are captured to augment Mexico City's water supply.

Ajusco is a lava dome complex of Pliocene-Pleistocene age, surrounded by block and ash flow deposits.

Parts of this range account for about half of the area of the Mexican Federal District, the rest of which is occupied by Mexico City.

The area around the peak is a popular destination for residents of Mexico City and tourists, with activities such mountain biking, horseback riding, motorcycling, hiking and climbing.

The Ajusco area is also home to Six Flags México (the largest amusement park in Latin America), the TV Azteca television network, the National Pedagogic University, the UNAM radio transmission center, the Fondo de Cultura Económica and El Colegio de México.
