In this extraordinary Baedeker--accessible, up-to-date, and prodigiously illustrated with photographs from Mariner 9, Viking, Pathfinder, the Hubble Space Telescope, and the ongoing mars Global Surveyor spacecraft--visitors will encounter:

• 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.
