Azanulbizar (Kh. "Valley of the Dim Rills";W. "Dimrill Dale"; S. "Nanduhirion") lay on the east side of the Misty Mountains, at the headwaters of the River Celebrant (W. "Silverlode"), and was tucked between the three great peaks of Fanuidhol, Caradhras, and Celebdil. It became a road which ran down toward Lórien. An enchanted lake called the Mirrormere (Kh. "Kheled-zaram") lay at the vale's center.
