As one of the largest geological features in the Solar System, the shield volcano Olympus Mons is truly impressive. In the days when we were limited to looking at Mars through telescopes, astronomers couldn't see Olympus Mons itself but they were able to discern the bright clouds that regularly appeared over the volcano. This lead astronomers to name this feature Nix Olympica, the Snows of Olympus. It wasn't until the Mariner 9 mission to Mars that we discovered the true nature of this feature: a massive shield volcano.
For purposes of comparison, find a geologic map of the state of Washington and look for the Mt. Saint Helens volcano. Once you've found it, consider it's size relative to the state of Washington. Now if we were to take a map of Olympus Mons and superimpose it on the map of Washington, Washington would disappear.
Clouds Over Olympus Mons Source Image Background
The image seen here is a composite of two Wide Angle Camera images taken by the Mars Global Surveyor in March 1999. The image is centered on 18.3° latitude, 134.2° longitude. The two Wide Angle Camera images cover the same geographic area but one image was made using the camera's red filter and the other using the blue filter. The area covered by the image shown here is approximately 850 kilometers wide.
