The snow-capped Falso Azufre volcanic complex rises along the Chile-Argentina border near Laguna Verde (upper left) in this NASA Space Shuttle image (with north to the upper left). The western portion includes Cerro Falso Azure, the high point of the complex, with prominent snow-covered craters. The eastern portion (toward the lower right) is located wholly in Argentina and contains small composite cones and lava domes (with lesser amounts of snow in this image) that appear to represent the most recent activity of the complex.
