On the border between Chile and the Catamarca province of Argentina lies a vast field of currently dormant volcanoes. Over time, these volcanoes have laid down a crust of magma roughly 2 miles (3.2 km) thick. It is tinged with a patina of various colors that can indicate both the age and mineral content of the original lava flows.
