It can see chakra through solid objects, can't it? >.>

If you can find me what chapter in the manga Sasuke looked through an object entirely, I'll accept it, but I don't remember Sharingan being capable of doing that at all. 

-EDIT- They saw chakra throughout the cave, us seeing the snakes past the pillars throughout the cave was so the reader knew what they were seeing: chakra, not through pillars themselves, but the chakra emanating from it. 

Even then, seeing through the ground and determining you were the target without having vision of him beneath the earth? Not really buying it man, but again, I really don't care enough to ask for an edit since he's going to eventually lose.
