The Mering Stream or (Sindarin) Glanhír formed the border between the realms of Gondor and Rohan, together with the White Mountains and the Mouths of the Entwash. West of the Mering Stream lay the Rohanese province of Eastfold and east of the river lay the Gondorian province of Anórien. The Mering Stream flowed through Firienholt, which grew about the mountain Halifirien, last of the Warning beacons of Gondor.
