By far the most interesting and well drawn place in the manga, where two of the best battles happened and where another one will happen too. It will be turned to dust by Naruto and Sasuke, damn you Kishimoto.
Was than dust, the whole landscape is about to change. just like the landscape where Naruto and Bee met Obito/ Tobi changed to where the S06P presently is.
One of those faces are going to be blown off in the valley when this is all over.. one big 'RASENGAN' and Madara's face is as good as gone.. and a slash of Sasuke's Susano'o.. Hashirama's statue would be nothing but breadcrumbs..
The place is going to be destroyed, it's going to be called the Valley of Beginnings after the battle with a Statue of Naruto and Sasuke built there. Just a prediction xD
