A line of hills to the southwest formed the southern boundary of Nevrast. In the south, it was an east-west range that divided Dor-lómin and Mithrim to the north from Beleriand to the south, then in the east it curved around to the northwest, forming the boundary of Hithlum and separating it from Anfauglith. The Mountains of Mithrim were a northwesterly spur that separated Dor-lómin from Mithrim.
The Ered Wethrin disappeared beneath the waves at the end of the First Age.
