The north Undeep, between the Field of Celebrant and the Brown Lands, as seen in The Lord of the Rings Online

The North Undeep and the South Undeep were two great westward lands of the Anduin, located between the Brown Lands and the great Wold of Rohan, east of Fangorn forest. They were strategic points when Eorl and his men came from the North to the Fields of Celebrant.[citation needed]
