Abridged History of the 10th Age
The most northerly mountains of Arinnfal, Hlutmont is riddled with mines. Many of these are potent sources of iron, though there are also copper, zinc, and silver. Almost without exception, these mines are on the south face of the mountains rather than the exposed north face. The area is not heavily terraced or farmed like other parts of Arinnfal due to the large amount of industry there.
