Amon Ereb
Amon Ereb (S. amon "hill" + ereb "isolated, lonely"), sometimes just Ereb, was the broad, shallow-sided hill that dominated the southern plains of East Beleriand.J.R.R. Tolkien, Christopher Tolkien (ed.), The Silmarillion, "Quenta Silmarillion: Of Beleriand and its Realms"The hill was the highest point in that region and the easternmost hill of Andram, but was standing alone. Within sight of the Gelion, it had tremendous strategic importance, because it guarded the eastern passage around the Long Wall of the Andram into the southern parts of East Beleriand and the northern Taur-im-Duinath.J.R.R. Tolkien, Christopher Tolkien (ed.), The Silmarillion, "Map of Beleriand and the Lands to the North"It was here that Denethor of the Nandor met his end in the First Battle.J.R.R. Tolkien, Christopher Tolkien (ed.), The Silmarillion, "Quenta Silmarillion: Of the Sindar" Much later, Caranthir fortified it to guard his escape into the south after the Dagor BragollachJ.R.R. Tolkien, Christopher Tolkien (ed.), The Silmarillion, "Quenta Silmarillion: Of the Ruin of Beleriand and the Fall of Fingolfin" and the Fëanorions withdrew there after Nirnaeth Arnoediad.

A small circle appears in Forlindon on Tolkien's early draft map for The Lord of the Rings.J.R.R. Tolkien, Christopher Tolkien (ed.), The Treason of Isengard, p. 302 Christopher Tolkien cannot explain this featureJ.R.R. Tolkien, Christopher Tolkien (ed.), The Treason of Isengard, p. 301 and notes that in his own 1943 redrawn map, the circular area is no longer present.J.R.R. Tolkien, Christopher Tolkien (ed.), The Treason of Isengard, p. 322 If one does a correct collage of Beleriand and Eriador maps, however, the small circular map seems to coincide with Amon Ereb.See notably the maps independently reconstructed by Charles Noad, "A Note on the Geography of the First Age" in Amon Hen no. 38, April 1979, reprinted in Mallorn no. 27, September 1990, p. 40; Ronald Kyrmse, "The Geographical Relation between Beleriand and Eriador" in Mallorn no. 26, September 1989, pp. 25–27; Didier Willis, "Du Beleriand aux confins de Rhûn" (French) in Tolkien, le façonnement d'un monde (2014), vol. 2, pp. 197-212. This might suggest that Amon Ereb was once thought to have survived the submersion of Beleriand, although there is no textual evidence for it.==Portrayal in adaptations==1982-97: Middle-earth Role Playing:In MERP, Amon Ereb does indeed survive the destruction of beleriand.http://vignette2.wikia.nocookie.net/merp/images/4/47/Forlindon.jpg/revision/latest?cb=20120930011312
