Many features familiar on Earth are displayed on a vast scale made more awesome by the planet's modest size. Great canyons are incised into the surface, huge dry river beds attest to past floods, volcanoes tower to heights almost three times that of Mt Everest, and vast seas of sand surround the poles. Global dust storms regularly cover the entire planet. At the poles, caps of carbon dioxide advance and retreat with the seasons. This book incorporates images acquired by the Viking orbiters, beginning in 1976. The pictures here represent only a small fraction of the many thousands taken, and were chosen to illustrate the diverse geology of Mars, and its atmospheric phenomena.''
