NASA's Mars Global Surveyor shows two views of the topography of a major volcano in the Alba Patera region on Mars.

Two views of Alba Patera with topography draped over a Viking image mosaic. MOLA data have clarified the relationship between fault location and topography on and surrounding the Alba construct, providing insight into the volcanological and geophysical processes that shaped the edifice. The vertical exaggeration is 10:1.
