“Nevado de Toluca” is a large stratovolcano in central Mexico, located about 80 kilometres (50 mi) west of Mexico City near the city of Toluca. It is generally cited as the fourth highest of Mexico's peaks, after Pico de Orizaba, Popocatépetl and Iztaccíhuatl. It is often called by the Nahuatl name Xinantecatl which is usually translated as “The Naked Lord”.
The volcano has a 1.5 kilometres (0.93 mi) wide summit caldera which is open to the east. The highest summit, 4,680 metres (15,354 ft) Pico del Fraile (Friar's Peak), is on the southwest side of the crater and the second highest, 4,640 metres (15,223 ft) Pico del Aguila (Eagle's Peak), is on the northwest. There are two crater lakes on the floor of the basin at about 4,200 m (13,800 ft), the larger Lago del Sol (Sun Lake) and the smaller, but deeper, Lago de la Luna (Moon Lake). [Wiki]
