"...[I]t seems possible that the Earth has been visited by various Galactic civilizations many times (possibly, during geological time). It is not out of the question that artifacts of these visits still exist...or even that some kind of base is maintained within the solar system to provide continuity for successive expeditions. Because of weathering and the possibility of detection and interference by the inhabitants of the Earth, it might have appeared preferable not to erect such a base on the Earth's surface."
--Carl Sagan, "Intelligent Life in the Universe"
Most of the images featured here, such as the "Face," "Fort" and "Main City Pyramid," can be seen in the map above. Also indicated are the "Mound" features under examination by Drs. Horace Crater and Stanley McDaniel of SPSR.
More of the Cydonia region is visible in the image above, though in less detail. The "City" complex can be seen on the far left; to the far right is the "Cliff" feature (next to "splash"-style impact crater). The "D&M Pyramid" is visible on the bottom. Analysis of the angular relationships between many of these features [including the "Mounds" (above)] suggests a mathematical preoccupation with 19.5 degrees.
