|“||The Mountain crept ever nearer, until, if they lifted their heavy heads, it filled all their sight, looming vast before them: a huge mass of ash and slag and burned stone, out of which a sheer-sided cone was raised into the clouds. Before the daylong dusk ended and true night came again they crawled and stumbled to its very feet.||”|
–The Return of the King, Mount Doom
Mount Doom is a structure in the Lord of the Rings Mod which, similarly to The Pits, always spawns in the same spot in every world. This location is just south of the Mount Doom waypoint, or around x=92718, z=60970.
Mount Doom is a large, very round mountain, which reaches a maximum height at y=232. At the top of Mount Doom, there is a crater full of lava.
This is the fifth structure that always spawns in the same place, regardless of the world.
