Great Tree

The Great Tree is an enormous oak growing in the Village Hidden in the Waterfall. The tree is described to dwarf mountains in size and has a vast network of branches stemming from its trunk. At the base of the tree is a cavity that serves as the entrance to a black site that the Hidden Waterfall uses for storage of sensitive intel. The site is under constant guard.

History
Sasuke Uchiha was spotted around the Great Tree by people of the Hidden Waterfall, who sent word to the Village Hidden in the Leaves for a request for help. Team Kakashi was sent, and they searched the Great Tree, as well as the Village and the territory outside, but they could find no sign of Sasuke. The Hidden Waterfall's leader, Shibuki, was thus satisfied that any potential threat had been assuaged.
