The linear grayish lava flow extending into two lakes at the center originated from the Achín-Niellu cinder cone in the snow-covered area at the bottom-center of this NASA Space Station image with north to the upper left. The distal end of 7.5-km-long flow forms a large delta into Lago Epulafquen. A cinder cone separates this lake (known in the Machupe language as "Two Lakes") from the large lake at the upper right, Lago Huechulafquen. The lake at the right-center is Lago Curruhué.
