A photographic study in Selenography (lunar geology), whereby an attempt is made to determine whether there is evidence (alien artifacts) for extraterrestrial activity on the moon and Mars. If aliens have been occupying our planetary neighbors, there should be some traces of their activities. George Leonard (Somebody Else is on the Moon), Fred Steckling (We Discovered Alien Bases on the Moon), and Richard Hoagland (The Monuments of Mars) say there are. This series of volumes uncovers the truth once and for all. Illustrated with hundreds of new enhanced B&W NASA photographs 340 pages.
