Chile - January 9th, 2011

Visible at the center of this orthorectified image is Maipo, a stratovolcano in the Andes, lying on the border between Argentina and Chile. It is located 90 km south of Tupungato and about 100 km southeast of Santiago.

Maipo retains a symmetrical, conical volcanic shape, unlike many of the other nearby peaks, making it the best known peak in the region, though it is not the highest. (Nearby Castillo is 5,485 m high.) Maipo is also almost the southernmost 5,000 metre peak in the Andes. (That honor goes to Sosneado, about 50 km to the south).

Maipo is located within the Diamante Caldera, a feature of about 15 km by 20 km size that is about one-half million years old. It rises about 1,900 m (6,230 ft) above the floor of the caldera. Immediately to the east of the peak, on the eastern side of the caldera floor, is Laguna del Diamante, a picturesque lake that formed when lava flows blocked drainage channels from the caldera in 1826. The lake covers a surface area of about 14.1 kmĀ² and is one of the largest freshwater resources in the Province.
