Cerros de Incahuasi, Volcanic summit in Antofagasta Region, Chile

Cerros de Incahuasi is a mountain of several summits in the Antofagasta Region of Chile, near Sico Pass, whose highest point reaches 5,634 m. It is the partly collapsed remnant of an ancient volcanic edifice, and its Incahuasi Sur volcano was active about 10.5 million years ago.

Cerros de Incahuasi is the remnant of an older volcanic edifice that partly collapsed, leaving several summits near Sico Pass. The Incahuasi Sur volcano in the range was active about 10.5 million years ago. It lies on the Calama–Olacapato–El Toro fault, which runs southeast from Incahuasi Sur.

The name Incahuasi comes from Quechua, meaning "Inca house", a term also used for the nearby Sico Pass. The range lies along the Calama-Olacapato-El Toro fault, which runs southeast from Incahuasi Sur and has drawn geologists studying the region's volcanic belt.

The remote location demands thorough preparation and specialized equipment before attempting to climb. Extreme altitude and harsh environmental conditions require proper acclimatization and suitable gear for safe visits.

Cerros de Incahuasi is the partly collapsed remnant of an older volcanic edifice, and its Incahuasi Sur centre was active about 10.5 million years ago. A volcanic belt and the Calama–Olacapato–El Toro fault run southeast from that centre, a structural line visitors can trace on maps of the range.
