On the border between Chile and the Catamarca province of Argentina lies a vast fieldof currently dormant volcanoes. Over time, these volcanoes have laid down a crust ofmagma roughly 2 miles (3.5 km) thick. It is tinged with a patina of various colorsthat can indicate both the age and mineral content of the original lava flows.
