Mitheithel

The river Mitheithel or Hoarwell was a great river of Eriador.

It began in the northern Hithaeglir and then sped through the Ettenmoors, after which it bent south. The Great East Road crossed it at the Last Bridge, after which it was met by the Bruinen, forming the Angle where the Dúnedain dwelt after the fall of Arnor.

From there the Mitheithel formed the northern border of Eregion, until it was met by the Glanduin at Swanfleet and became the Gwathló.
