Publisher's Synopsis
- Olympus Mons, the largest volcano in the solar system, rising three times as high as Mount Everest and covering an area the size of Missouri
- Tharsis Planitia, the "high plains of Mars," with plains rising 29,000 feet-wide enough to cover Europe.
- Valles Marineris, an equatorial canyon so vast that America's Grand Canyon would be a mere tributary.
Plus: the "face" on Mars, the White Rock, the "Canals" of Xanthe-and the first possible evidence of an ancient Martian life-form.
