The article is on the pool just below Henneth Annûn. For the chapter in The Two Towers (novel) see: The Forbidden Pool.

"Far below them they saw the white waters pour into a foaming bowl, and then swirl darkly about a deep oval basin in the rocks, until they found their way out again through a narrow gate, and flowed away, fuming and chattering, into calmer and more level reaches." --The Two Towers

The Forbidden Pool was a basin of water created by the waterfall concealing one of the two entrances into the hiding place of the rangers of Ithilien. The rangers set a penalty upon the pool; that to enter its waters was to forfeit one's life. Gollum, searching for fish, chanced to find the pool by accident, but was spared death thanks to his master, Frodo Baggins.

Behind the ScenesEdit

It was revealed in the appendices of the film that the water used for the pool had chemicals in it to produce believable foam.
