Cajón del Maipo
Cajón del Maipo is a canyon located in the southeastern portion of the Santiago Metropolitan Region of Chile. San José de Maipo is the capital of the commune that includes the entire Andean sector of the Metropolitan Region.
The canyon encompasses the upper Maipo River basin which features a series of confluent rivers including El Volcán River, Yeso River and Colorado River as well as minor streams that include San Gabriel, Manzanito, Coyanco, El Sauce, El Manzano and San José.
The valley is surrounded by some of the highest peaks in the region including the San José, Maipo and Marmolejo volcanos. The canyon is a popular tourist destination, especially for trekking.
The Maipo volcano is located in the Andes Mountains approximately 100 km (62 km) southeast of Santiago, Chile, on the border with Argentina. Maipo is one of the most active Chile-Argentina border volcanoes.
Rising to an elevation of 5,264 m, (17,270 ft) above sea level, the stratovolcano has a symmetrical, conical shape. Its cone towers about 1,900 m (6,230 ft) above the floor of the Diamante caldera.
The Diamante caldera was formed during a major explosive eruption about 450,000 years ago. It covers an area of approximately 15 x 20 km (9 x 12 m) on the border between Chile and Argentina.
Lake Diamante is located to the immediate east of the Maipo volcano, on the eastern side of the Diamante caldera, within Argentine territory. The lake formed when drainage channels from the caldera were blocked by lava flows during an eruption in 1826. The lake is a popular tourist destination.
San José Volcanic Group
The San José Volcanic Group is a massive volcanic group on the Chile-Argentina border at the end of the Cajón del Maipo. The complex covers an area of approximately 10 km (6 mi) x 5 km (3 mi).
The San José volcano, from which the group takes its name, is a stratovolcano on the south end of the group. The complex includes the La Engorda, Espiritu Santo, Plantat and Marmolejo volcanos. The Marmolejo volcano lies on the northern end of the group.
