Mars April 25, 1998 Mars Global Surveyor views Olympus Mons -- taller than three Mount Everests and about as wide as the entire Hawaiian island chain. This giant volcano is nearly as flat as a pancake. That is, its flanks typically only slope 2 to 5 degrees. The Mars Orbiter Camera (MOC) obtained this spectacular wide-angle view of Olympus Mons on Mars Global Surveyor's 263rd orbit, around 10:40 p.m. PDT on 25 April 1998. In the view presented here, north is to the left and east is up.
