Volcanoes in Chile, South America
On the border between Chile and the Catamarca province of Argentina lies a vast field of inactive volcanoes. Over time, these volcanoes have laid down a crust of volcanic rock about 3.5 kilometers (2 miles) thick. This crust is tinged with various colors depending on the age and mineral content of the original lava flows. This mountainous region has little vegetation.
