Abismo de Helm
Upstream from Edoras, deeper into Harrowdale, are the hamlets of Upbourn and Underharrow. At the head of Dunharrow (from Old English "Dûnhaerg", "the heathen fane on the hillside") is a refuge, Firienfeld, in the White Mountains. Aldburg, capital of the Eastfold, is the original settlement of Eorl the Young. The Hornburg, a major fortress guarding the western region, is in Helm's Deep, a valley in the White Mountains.
