Dunharrow
The map of Dunharrow is based on the drawing by Tolkien as well as on the text. Harrowdale was about half a mile wide where the road from the hills to the west, the road to Dunharrow and the road to Edoras met. The Muster took place here, at a place where the Snowbourn ran close to the western hills.
Two villages are mentioned as lying between Edoras and Dunharrow: Underharrow and Upbourn. Only Underharrow appears on the map. (The Muster of Rohan: Bk 3).
The Dwimorberg, beneath which Dunharrow and the Dimholt Gate were situated, was south of the mountain Irensaga and north of the Starkhorn. (The Muster of Rohan: Bk 3: See also Map 42).
The road to the Hold on Firienfeld led up some hundreds of feet to a shelf in the eastern cliffs, winding steeply with a stone ‘Pukel-man’ at each turn. At the top of the road to the Dark Door was lined by standing stones. The camp was mostly to the right of the road and the Gate itself was hidden among dark trees, though they do not appear in the picture. (The Passing of the Grey Company; The Muster of Rohan; Bk 3).
