Cerro Galán is a caldera in Catamarca Province, Argentina, considered to be the best exposed large caldera in the world.[citation needed] It was formed 2.2 million years ago when 1,050 km3 of material was erupted, producing ignimbrite deposits stretching up to 100 km away. The caldera was originally the site of a large lake, but resurgence of the eastern caldera floor has confined the salty Laguna Diamante to the caldera's western edge.
