Wall of Andram.
The Long Wall.
Cutting through central of Beleriand was the Wall of Andram. When comming from the North and Taleth Dirnen it might not have seen evident because of the fall of the land from North to South but seen from South it appeared as an endless chain of hills. In the West the outcrop of the Wall there were many caverns and gorges and Ringwil floved in thiese and from the North-edge had Narog been cutting through and ran benieth the terraces of Nargothrond. Near the middle of Andram came Sirion from the North and Aelin-Uial and plunged underground at the North-edge of the wall until it issued 9 Miles further South at the walls feet through the Gates of Sirion. The Wall ran from West to East South-East for 350 Miles but as it ran Eastward the hills became lover until they merely was flat hills The last hill of the Wall was named Ramdal. But 25 Miles further East was a high hill Amon-Ereb. The South-Western end of the Wall of Andram was also called the High Faroth ( Where Narog comes out of the gorges.)
