The Face on Mars (i.e. the Cydonia Masif) Rendered from a combination of NASA data sources. The low resolution height field was created by NASA from the original Viking image. I then enhanced it with details from Mars Global Surveyor image E03-00824. Texture details were cloned from satellite images Morocco (for the exposed rock) and The Sahara (for the sand). The color is fictional, as is the Marsbase.
