how can we say that olympus mons is 21,230 meters tall if mars has no sea-level to measure from?
As far as I know, all mountains on Earth have their respective hight determined by the Earths sea level. Mars has no sea, and in return, shouldn't have an anchor to measure its terrain features. How do you then determine the hight of the mountains on Mars?
