Nen Hithoel

Nen Hithoel was a large lake upon the Great River Anduin amid the Emyn Muil, east of Rohan.
The lake was approximately twenty miles long from north to south, and ten miles wide. Upon the lake's northern approach, the Men of Gondor constructed the huge pillars of the Argonath in the reign of Rómendacil II to mark the northern boundary of their realm, although by the time of the War of the Ring that boundary had long since receded. At the southern end of the lake stood three hills. Amon Hen was the location of Seat of Seeing, stood upon the western shore and Amon Lhaw, the Seat of Hearing upon the east. The third hill formed an island in the lake itself, Tol Brandir. None ever set foot upon the island due to the intense currents at the lake's south end by the Falls of Rauros.
A stair built by the Men of Gondor allowed passage from Nen Hithoel down to the river below the Falls.
== History ==
The Fellowship of the Ring arrived at Nen Hithoel on February 25, 3019 and made camp at Parth Galen close to Amon Hen. The fall of Boromir and the breaking of the Fellowship occurred soon afterwards. Frodo and Sam took a boat for the eastern shore, Merry and Pippin were captured by Orcs, and after sending Boromir's body over the falls in another boat, Aragorn, Legolas and Gimli, as "the Three Hunters", set out to track the Orcs and rescue Merry and Pippin.
