Red Mountains

The Red Mountains (Orocarni) are a mountain range in the far east of Middle-earth within Rhûn. They are rich in minerals (excluding Mithril which is only found in the Misty Mountains), containing twice as many ores as most other biomes.

The Red Mountains consist of a red stone called Sarncaran. From this stone, bricks and other building blocks can be made. At y = 90 and below, grass blocks will generate, with trees such as larch and spruce. High up in the mountains, snow will generate. Mobs found here (Cows, Boars, etc.) can spawn at higher levels than the grass blocks. When you enter this biome, you get the achievement "Mountains of the East". This biome does not have a Fast Travel point.

The sky in this biome is tinged a pale red colour.

Red Mountains Foothills
The Red Mountains Foothills sub-biome surrounds the mountains. They are grassy and contain spruce, oak and larch trees. Sarncaran stone spawns underground here in patches.

Mobs
The Red Mountains were home to four clans of Dwarves, about which very little was known. A Red Dwarves faction is planned to be added to the mod, encompassing all four of these dwarf clans, along with corresponding structures, equipment, crafting table, et cetera. For now, the only mobs that spawn here are the normal Minecraft animals and boars. The four clans were Stiffbeards (ones that lived in the north) Ironfists (ones that live north-middle) Black Locks (ones that lived in far southern) and Stonefoots (ones that lived in center southern) - Ruled By SpeedySC on official LOTR server

Mining
This biome is very important for mining, not only because the red Sarncaran stone spawns at the surface and in underground patches, but also because this biome contains twice as much ore than any other biome in the game.

Vegetation
The Red Mountains themselves are bare of life, but the foothills are full of larch, spruce, and oak trees. The Red Mountains Are Not That Bare, They Have Maple Trees, Oak, Larch, And Spruce all Spawning. Maple Is Very Abundant There
