Evidence: Both seem to resemble a simple mesa, a natural landform quite common on Mars. The 1998 photograph was slightly blurry, so three years later Michael Malin and his crew returned to the Red Planet, to the Cydonia region. Mr. Malin set the Mars Global Surveyor camera to maximum resolution, and snapped an excellent picture from above the Face. And, going even further, I will point out that each pixel in the 2001 photograph spans1.56 meters, as the Viking I's 1976 photo spans 43 meters per pixel. As you can see, this is a significant difference and must not be overlooked.
