Mountains



Mountains or Extreme Hills are common cold and snowy biomes. There are four (nine) used variants and one (two ) unused variant in the biome family.

Description
Mountain biomes feature steep terrain and reach higher elevations than any other biome in the game other than the shattered savanna biomes. The surface is made of grass block, stone, ores and gravel. The standard mountains biome generally peaks at roughly Y-level 140. As the climate is cold, rainfall changes to snowfall above approximately Y-level 92 where stacked snow layers form on blocks above that point, along with water freezing into ice. The grass and leaves are an aqua color, just like those in snowy tundra biomes or taiga biomes. Llamas and goats may spawn in mountain biomes; they are the only places where goats can spawn and one of two places llamas can spawn, the other place being savanna biomes. Additionally, emerald ore exclusively generates in mountain biomes and infested stone patches generate below sea level.

The exact height at which rain ends and snow starts is randomized between Y levels 91 and 98. More specifically, the lowest possible snow layer should form at Y level 91, and the lowest height at which snow always forms is Y level 98.

Mountain biomes have some unusual features and formations compared to other biomes due to the terrain generation algorithm.

Floating blocks and even small floating islands are common, as are overhangs and large waterfalls (occasionally, even lavafalls). This can create some impressive views at times. These oddities are magnified in shattered savannas.

Survival in mountain biomes can be challenging to beginners, due to the heights often risking heavy fall damage and higher elevations bringing snow and ice, but can be fairly easy once the player has acclimated to the area and found or made a flat-enough space for shelter. Llamas can also serve as useful pack animals when tamed. Water must be protected by light or a roof to prevent it from freezing when above the snowfall line, however, and the player must be aware of their surroundings to avoid falling off steep cliffs, especially when fighting hostile mobs. Care should also be taken when mining in mountain biomes, due to infested stone occasionally generating; the player might get swarmed with silverfish if they're not prepared.

Water buckets can be used to climb mountains, by dumping the water onto a higher ledge and climbing up to the ledge. The player can safely collect the water into the bucket and repeat the procedure until the player is on top of the mountain. Water can also be used to collect snowballs from the mountains if snow generates there.

Mountain biomes generate within clusters of lush and cold biomes, commonly found next to taiga, forest, or plains biomes. Oak trees occasionally generate in place of some spruce trees.

Variants
There are a total of five (eleven ) mountain variant biomes, including one whose generation has been discontinued in new worlds.

Extreme Hills
The mountains or extreme hills biome is the normal mountain variant. This biome features the standard stony and grassy terrain, with a bit of tall grass (and sporadically generated oak and spruce trees).

Llamas can spawn here, and silverfish-infested blocks and emerald ore generate naturally.

Wooded Mountains
The wooded mountains generate groves of oak and spruce trees. This variant does not feature the stony terrain so that the trees can generate. This biome also generates standalone as a thick separation when a desert is bordering a snowy biome.

While the increased wood supply can be useful, the risk of fatal fall damage still exists, especially if this variant generates on the edge of a mountain range and border a river or another low-elevation biome.

Wooded mountains use the same mob spawning chances as extreme hills.

Gravelly Hills
The rare gravelly mountains or gravelly hills variant replaces the top few layers of stone and grass with gravel across its landscape.

Due to the gravel replacing most of the grass, trees generate far less often, making this variant relatively barren. Players should be careful when surfacing from underground in this biome, as the top layers of gravel can pose a suffocation hazard.

Gravelly mountains use the same mob spawning chances as extreme hills.

Gravelly Mountains+
Gravelly mountains+ (also reffered to as modified gravelly mountains in the F3 menu) is a rare variant of the wooded mountains biome that has the exact same features as the regular gravelly mountains, making this biome indistinct from the former. The peaks are still covered in gravel, large valleys often generate among the peaks and the trees are still quite sparse in this biome, making this a difficult biome for survival, due to its barrenness being combined with steep terrain. Differently however, it can rarely generate standalone as a thick separation when a desert lakes biome is bordering a snowy taiga or tundra.

Gravelly mountains+ use the same mob spawning chances as extreme hills.

Mountain Edge
The mountain edge variant is a currently unused variant. Similarly to the jungle edge biome, it was a technical biome intended to provide a smooth transition from other biomes to the mountains. It is similar to the taiga hills biome, but with a few oak trees. The terrain was gentler and not as steep as the normal mountains, with oak and spruce trees growing. This biome was phased out in the Java Edition 1.7.2 update development and does not generates naturally, though can still be seen using the Buffet world option or addons.

Mountain edges use the same mob spawning chances as extreme hills.

Upcoming
There are 5 additional height-dependent sub-biomes which make up an uncommon mountains biome. These several biomes can occupy the same X and Z coordinates, varying only along the Y level, and are cold (in the case of mountain meadows) or snow-covered. Coal, iron and emerald ores can be found at higher altitude than other biomes. In Bedrock Edition, these biomes are bordered by forest or flower forest and do not generate stone shores when next to an ocean (forest will just cut to ocean instead). These new mountains generate with either plains, deserts, forests, jungles, any oceans or snowy tundras as base biomes, which result being connected or even completely surrounded by those biomes. In Java Edition, these biomes don't generate a forest or flower forest border, so they can generate from sea level altitude, and all of them can generate pillager outposts, with the meadow also being able to generate villages.

Mountain Meadow
The meadow features an almost flat field filled with patches of flowers and turquiose-green grass or double tall grass, where sheep, donkey and rabbits spawn. In Bedrock Edition, sweet berry bushes, cornflowers and dandelions can be found here. $$, all small flowers generate except blue orchids, tulips, lilies of the valley or wither roses. Trees do not naturally generate here in Bedrock Edition, however, in Java Edition, oak and birch trees, pillager outposts and villages can. Those trees often have bee nests. Meadow villages look like plains villages.

Mountain Grove
The grove creates a forest of spruce trees on the lower slopes of a mountain. Rabbits spawn in this biome even though grass blocks are not going to generate. The water will freeze into ice and the surface is also covered with snow, snow blocks and a lot of powder snow.

Snowy Slopes
The snowy slopes feature steep terrain leading up to the peak biomes and is also covered in snow, snow blocks and powder snow. Goats and rabbits can spawn in this biome. On north and east sides of mountains, it can also generate with stone instead of snow blocks and dirt.

Lofty Peaks
The lofty peaks is one of the three highest mountain biomes, which rarely reaches up to y=260. Which peaks biome generates depends on temperature, with this biome usually generating in areas with temperate biomes such as dark forests and birch forests. This biome will only generate on mountains that are tall enough to generate it. It is covered with snow blocks. $$, goats can spawn in this biome.

Snow Capped Peaks
The snow capped peaks is one of the three highest mountain biomes, which rarely reaches up to Y=260. Which peaks biome generates depends on temperature, with this biome usually generating in areas with cold and snowy biomes such as taigas and snowy tundras. This biome will only generate on mountains that are tall enough to generate it. It is covered by snow, ice, and patches of packed ice. $$, goats can spawn in this biome.

Stony Peaks
The stony peaks is one of the three highest mountain biomes, which rarely reaches up to Y=260. Which peaks biome generates depends on temperature, with this biome usually generating near dry and tropical biomes such as deserts, savannas, badlands and jungles and it doesn't generate snowy slopes in the lower areas. This biome will only generate on mountains that are tall enough to generate it. It is covered by stone and gravel. The grass in this biome has a light green color slightly more vibrant than the plains grass color. Goats can spawn in this biome.
