So this is the animation that supports it being some kind of face carved into a Mesa
As does this one.
This one doesn’t though.
The first image of it was shot by Viking 1 on July 25, 1976. It is one of the Cydonian mesas, situated at 40.75° north latitude and 9.46° west longitude. It was discovered by two NASA engineers sorting through the photos.
I have to agree with the NASA line of it being an optical illusion.
Likelihood of it being a real alien carving… 1%
I never say never. But I’ll eat my hat if it’s true.
