The late-Pleistocene Sierra Nevada in Chile has a N-S oriented glaciated ridge and a 7-km-long E-W alignment of fissure vents in the center of this Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 40 km across). Steep cliffs on the western side expose the stratigraphy of the summit area.
