Acamarachi

Stratovolcano · Chile · 6023m

Acamarachi, an impressively steep-sided andesitic-dacitic volcano with slopes that reach about 45 degrees, towers above Laguna Aguas Calientes. The 6046-m-high Acamarachi is the highest peak in this part of the northern Andes and lies at the SSE end of a small volcanic complex that extends from the neighboring volcano Colachi. A poorly preserved summit crater and the absence of youthful flank lava flows suggest that Acamarachi was largely constructed in pre-Holocene times, although the summit lava flows may be younger.

Geological summary

Acamarachi, a steep-sided andesitic-dacitic volcano, forms the highest peak in this part of the northern Andes. Also known as Cerro Pili, it is at the SSE end of a small volcanic complex that extends from the neighboring volcano Colachi to the NNW. A large lava dome is located on its N flank. A poorly preserved summit crater and the absence of youthful flank lava flows suggest that the volcano was largely constructed in pre-Holocene times, although the summit lava flows draping the upper cone were considered to be of Holocene age (González-Ferrán, 1995).

From Wikipedia

Acamarachi is a 6,046-metre (19,836 ft) high volcano in northern Chile. In this part of Chile, it is the highest volcano. Its name means "black moon". It is a volcano in the Central Volcanic Zone of the Andes, a zone of strong volcanic activity during the last million years. Old volcanoes in the area are well-preserved, due to the dry climate.
