In 1976, NASA sent four Viking spacecraft to Mars to photograph the planet, including a milelong mesa that uncannily resembles a human face. In this wideranging and profound analysis of the Mars data, Hoagland takes readers step by step through these NASA images and the evidence that a highly advanced civilization may have lived and built upon Mars hundreds of thousands of years ago. 50 photographs; 10 line drawings; maps and charts.
