Yellow Mountains
From Tolkien Gateway
The Yellow Mountains were a range of mountains to the South-East of Middle-earth, a southern continuation of the Red Mountains. Both ranges were created when the Valar thrust the center of Middle-earth to the east as extra protection for Valinor.[1]
We don't really know anything on the fate of the mountain range but it may have felt the effects of the War of Wrath and were ruined.
