From Wikipedia, the free encyclopedia.
The Ered Lithui (Sindarin for "Mountains of Ash") is a fictional mountain range in J. R. R. Tolkien's Middle-earth.
From the Morannon, where it meets the Ephel Dúath, the Ered Lithui runs generally eastward for hundreds of miles, forming an impenetrable northern border of Mordor. The name "Mountains of Ash" suggests that the range is downwind of Mount Doom and collects its ash fallout.
