Rucapillan--house of the spirit--it's called by indigenous Chileans known as the Mapuche. And what a spirit it has, this volcano in south-central Chile that's perhaps best known as Villarrica. The volcano, one of Chile's most active, rises above a lake and town of the same name 470 miles south of Santiago.
Villarrica is the westernmost of three large volcanoes that run perpendicular to the Andean mountain chain. Pictured here, geologist Jeff Johnson works in the inner crater of Villarrica.Image credit: Richard Sanderson
