Descent into the Caviahue caldera from Copahue volcano

by Jonas Kuhn, Heidelberg University, Heidelberg, Germany

After fieldwork at the crater rim of Copahue volcano, two researchers descend on its flanks down toward the Caviahue caldera. The picture is taken with a near infrared-converted camera, enhancing the contrast between vegetation and blue sky or lakes.
