Mountains of Shadow

A range of mountains that ran north to south between Ithilien and Mordor, and formed the western border of Sauron's Dark Land. Also known by the Elvish name of Ephel Dúath, their main pass was through the valley of Imlad Morgul, guarded (at the time of the War of the Ring) by the tower of Minas Morgul. In their northern parts, the mountains had a series of ridges and hills on their eastern side, known as the Morgai.

The Mountains of Shadow on the borders of Mordor are not to be confused with the Ered Wethrin that bordered the land of Hithlum, north of Beleriand, and whose name is also translated into English as 'Mountains of Shadow'.
