Acamarachi Volcano

Acamarachi is a stratovolcano situated in the Antofagasta Region, northern Chile. It is 6,046 m high and lies northeast of the volcanoes Aguas Calientes and Lascar. The Acamarachi volcano lies on a high plateau called Puna de Atacama and contains a steep-sided cone with slopes which reach 45 degrees.

The Acamarachi has a geologically old summit crater, and a large lava dome on the north flank. The summit crater contains a lake about 10-15 m in diameter, which is possibly the second highest crater lake in the world. The summit lava flow dates back to the Holocene era. A long time ago, the volcano was an Inca sanctuary. Metal and textile artifacts have been found, which are exhibited at the R. P. Gustavo Le Paige Archaeological Museum in San Pedro de Atacama.
