The broad glacier-covered summit of Volcán Copahue along the Chile/Argentina border is seen from the SE with conical Callaqui volcano in the distance. The lake-filled active crater of Copahue (lower center) has been the site of historical eruptions. The composite cone was constructed along the Chile/Argentina border within an 8-km-wide caldera formed 0.6 million years ago. The eastern summit crater is part of a 2-km-long, ENE-WSW line of nine craters that cuts across the western rim of the caldera.
