The Ash Mountains or the Ered Lithui was a mountain range that formed the northern border of Mordor.


According to the The Atlas of Middle-earth, the range was some 500 miles in length stretching from the Black Gate and Cirith Gorgor, where it met the Ephel Dúath in the west and Rhûn in the far east. Barad-dûr stood on an outcrop of this range on the plateau of Gorgoroth to its south.[1]These mountains were probably heavily blackened by the volcanic activity of Mount Doom hence the name.
