This APM image shows the Nevado de Toluca (center left), a large stratovolcano in central Mexico, located about 80 km west of Mexico City near the city of Toluca. The volcano has a 1.5 km wide summit caldera which is open to the west.
It is generally cited as the fourth highest of Mexico’s peaks, although by some measurements, Sierra Negra is slightly higher. The highest summit, 4680 m Pico del Fraile (Friar’s Peak), is on the south side of the crater and the second highest, 4640 m Pico del Aguila (Eagle’s Peak), is on the north.
There are two crater lakes on the floor of the basin at about 4200 m, the larger Lago del Sol (Sun Lake) and the smaller, but deeper, Lago de la Luna (Moon Lake).
