White Mountains (Middle-earth): The White Mountains, a loose translation of the Sindarin Ered Nimrais "Whitehorn Mountains", is a fictional mountain range in J. R. R. Tolkien's Middle-earth.  The mountains are named after the glaciers of their highest peaks.  The range lies mostly East-West, but also has a northern section, which is separated from the main line of the "Hithaeglir" Misty Mountains by the Gap of Rohan.  Even at the southern latitude of Gondor and Rohan, the White Mountains bear snow even in summer, suggesting they are extremely high.  The range has no passes.  The Paths of the Dead pass under it, but only the most courageous (or foolhardy) ever venture that route.  The White Mountains form the northern boundary of Gondor and the southern boundary of Rohan except in their easternmost provinces, where Gondor's province of Anórien lies to the north of the mountains.
