Also called Orodruin and Mount Doom, Amon Amarth is the Elvish name meaning "Mount Doom". The mountain was given this name when its fires started up again after Sauron returned from Númenor.

Amon Amarth is a volcanic mountain on a barren plain in the land of Mordor. It was in the fires of the Cracks of Doom on Amon Amarth that Sauron first forged the One Ring.

And it was back to this mountain that the Ringbearer Frodo Baggins brought the Ring in order to destoy it.
