Cerro Solo, Stratovolcano in Copiapó, Chile.
Cerro Solo is a stratovolcano in the Andes on the Chile-Argentina border that rises to about 6.215 meters. Its slopes display the typical structure of a volcanic peak with exposed rock layers from past eruptions.
The peak was first summited in 1950 by a group of Chilean mountaineers who established the initial climbing route. Its formation traces back to ancient volcanic activity that shaped the central Andes region.
The territory surrounding Cerro Solo forms part of the Catamarca High Andean and Puna Lakes Ramsar Site, preserving natural mountain ecosystems.
Access is via marked hiking trails that demand proper preparation and specialized gear for the high altitude. The climate at this elevation is harsh, and visitors should plan for changing weather and adequate acclimatization time.
The volcano contains nine separate eruptive centers developed through different volcanic episodes rather than a single cone. Light-colored rhyodacite deposits visible in the slopes come from ancient pyroclastic flows and give it a distinctive appearance.
