Was there photoshop when Viking circled Mars?
If the Face was alone, then yes, a trick of light. But it isn't!
Look at the giant pyramids... inside the structre are 4 smaller mounds (forming the points of a square). Inside that square is a dip. You can draw a
straight line from the dip right through the mouth of the Face.
Now take the SE pyramid. Draw a straight line from its SE corner... you'll come across the D&M pyramid, a 5 sided structure resembling Di Vinci's
"Man in a Circle"; the line you drew connects to the left arm. Draw a straight line rmitting from the head of this 5-sided pyramid... in perfectly
bisects the Face in half.
You now have a right angle triangle.
Go back to the "City" (Pyramids). Just to the NE of this is probably the most interesting feature which doesn't get nearly enough press; "The
Fort". Three sided, hollow (it seems more like a triangular wall). The bottom left corner appears to have the image of a nose or spaceship (1950's
design). This has been speculated to have been the living area (more details on this below). The corner on the bottom right, however, points to the
Face!
Now go to the Face again. Draw a straight line from the mouth to the right, and you;ll come across a crater. On that crater, at about the 1:00
position is a cone pyramid built ontop the crater debris. On the crater side facing the Face is a cliff like obtrusion, built again ontop the crater
debris. Analysis shows that, viewed from the City center (the dip), if the "cliff" was not there, then the crater rim would be in view.
And yes, there have been other features found on Mars; it's just that the Face is the most famous, and the surrounding structures add more to the
picture of that area (when viewed as a whole).
*I've read Richard Hoagland's book "Monuments of Mars" quite a few times*

These are the people who brought the Face to light, and have discovered the other key structures in the Cydonia landscape.
