Could these "structures" be optical illusions of natural geological formations? Of course. But to dismiss them outright as not possibly being artificial in origin is just as unscientific as declaring that they absolutely are created by intelligent beings. The suggestion that they are artificial is such a large claim, however, that these images should be examined carefully and with skepticism - but with an open mind. These images of seemingly artificial structures could dissolve into natural formations with more detailed, higher resolution photographs - just as, by most examinations, the so-called "Face on Mars" has resolved into a large mesa.
