Explore yourself. First click that link and make full zoom. Then in the righ corner, click on longitude, then enter those land marks, then click on explore mark in the right side.

These Map images were taken by NASA's Messenger Spacecraft. But NASA never said what is this. It is unusual in this map. It is in very bright color,  has no shadow. Something odd, may be UFO or large Alien Space craft.
