In the Andean mountain range lies a volcanic caldera named Laguna del Maule. Stretching roughly 15 by 25 kilometers (9 by 15 miles) across, it straddles the border between Chile and Argentina. Within the northern part of the caldera lies Maule Lake, surrounded by a complex volcanic landscape.
This perspective image was assembled from data acquired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite on April 9, 2003. ASTER produces images using infrared, red, and green wavelengths of light. Vegetated areas range in color from red to pink, snow is white, water is black, and bare rock is earth-toned.
