July 19, 1995 The Mountains of Mars Picture Credit: NASA,Viking Project Explanation: Volcanic activity on Mars has produced towering mountains. The largest one, Olympus Mons, is pictured here in this Viking Orbiter image. Olympus Mons is a shield volcano nearly 15 miles high and over 300 miles wide at its base. By comparison, Earth's largest volcano, Mauna Loa in Hawaii, is just over 5 miles high and about 12 miles wide. For more information about volcanic mountains on Mars see Calvin J.
