The regions of Anórien, with its capital Minas Anor, and Calenardhon, with fortresses at Isengard and Helm's Deep, lie to the north of the White Mountains. Calenardhon was granted independence as the kingdom of Rohan. To the northeast, the river Anduin enters the hills of the Emyn Muil and passes the Sarn Gebir, dangerous straits, above a large river-lake, Nen Hithoel. Its entrance was once the northern border of Gondor, and is marked by the Gates of Argonath, an enormous pair of kingly statues, as a warning to trespassers. At the southern end of the lake are the hills of Amon Hen (the Hill of Seeing) and Amon Lhaw (the Hill of Hearing) on the west and east shores; below Amon Hen is the lawn of Parth Galen, where the Fellowship disembarked and was then broken, with the capture of Merry and Pippin, and the death of Boromir. Between the two hills is a rocky islet, Tol Brandir, which partly dams the river; just below it is an enormous waterfall, the Falls of Rauros, over which Boromir's funeral-boat is sent. Further down the river are the hills of Emyn Arnen.
