I found a dark tower in the northern ice caps of Mars. The dark tower was blurred out a bit from NASA using their photoshop software to blur out structures, but fortunately they missed some area. I in turn used my software to bring back its true detail. As you can see, there is a tall tower which has a top that is in the shape of a U. I also circled some other structures, but they are difficult to see and most people wont be able to see them. Finding and seeing these objects comes with practice.
