Olympus Mons

The largest volcano in the solar system is Olympus Mons, shown in the image to the left. Olympus Mons is three times as high as the largest mountain on Earth, Mt. Everest, and is as wide as the entire chain of Hawaiian Islands! Measurements returned by Mars Global surveyor show the unbelievable size of Olympus Mons.

Mars has several other *very* large volcanoes. Some of them are found on top of a big bulge in the side of Mars called the Tharsis Ridge.
