Trivia
The Final Valley is where in the Anime, Naruto and Sasuke fought their first and last battle.The Last battle resulted in the destruction of the statues of Madara Uchiha (At the left) and Hashirama Senju (at the right) it was because when Naruto and Sasuke had run out of Chakra they resorted to their most commonly used jutsu (Naruto) Rasengan and (Sasuke) Chidori, this caused an explosion as the two jutsu were of high caliber.
