The mysterious object can be located at 71 49’19.73″N 29 33’06.53″W using the Google software. If the real mystery to you is that Google has mapped Mars, then that one is easily solved at http://earth.google.com/mars/.
David Martines estimates that the object is 700 feet long. Whatever this might be, Bio Base Alpha, Space Trash, Alien Utopia, or Google glitch or prank, there’s definitely something showing on Google Mars at the aforementioned coordinates. In a fun game of what do you see, at 3:18 of the video, do you spot anything odd as David zooms out?
