Concluding Statement: Even thoug hmy colleague still believes in the "Face on Mars" to be a alien made structure. I still believe it's only a butte or mesa. With my evindence of the "Face on Mars" only looking like a face due to the techonology of the time, the shadows of the sun, the angle the picture was taken, and our ability to see faces when none are there, I believe I have conclusive evidence that the "Face on Mars is nothing but a butte or mesa.
