Amon Ethir
Amon Ethir (S. Amon "hill" + ethir "spy") was raised artificially by the people of Finrod in the wide plain of Talath Dirnen, a league east of the Doors of Felagund above the river Narog. Over the years, trees grew on its flanks, but from its clear summit the watchers of Nargothrond could watch the lands about with the clear sight of the Elves, and so the hill got its name, Amon Ethir.[1]:205
After the Sack of Nargothrond, the hill still stood, and it was here that Niënor encountered Glaurung the Dragon. Having plunged the land into a thick fog of dragon-reek, so that only the hill remained above the mists, he cast Nienor into a deep spell of forgetfulness. After the departure of the dragon, Mablung found Niënor in a daze upon the hill and led her away.[1]:208-210
