The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Acamarachi (also known as Cerro Pili) volcano is a stratovolcano in northern Chile. The andesitic-dacitic volcano has very steep slopes (45 deg angle) and forms the highest peak in this part of the Andes.
The volcano contains a poorly preserved summit crater and a large lava dome on the north flank. There are no known lava flows from Holocene times, suggesting the volcano might be extinct.
The summit crater contains a lake about 10-15 m in diameter, which is possibly the second highest crater lake in the world.
Acamarachi is located very close to Colachi volcano, which is only 6 km NNW, but both volcanoes have independent magma systems.
