Mountains

Mountains refer to six somewhat rare cold, snowy, and temperate biomes.

Description
These are the six related sub-biomes that generate in mountainous terrain in areas with low erosion values. They all can generate pillager outposts, with the meadow also being able to generate villages and snowy slopes being able to generate igloos. Some of these biomes are the only places where goats can spawn in the game. Just like the windswept hills, emerald ores can be found in these biomes, especially at higher altitudes and both coal and iron ores are commonly found in the peaks.

Variants
There are six sub-biomes that can make up the mountains.

Slopes
These are the three biomes that can make up the slopes of mountains.

Meadow
The meadow is a grassy biome filled with patches of flowers and turquoise-green grass and tall grass, where sheep, donkeys and rabbits spawn. All small flowers generate except blue orchids, tulips, lilies of the valley or wither roses. Rarely, a lone oak or birch tree of any size can generate and always has a bee nest. Both pillager outposts and plains villages can generate in this biome, making this the only mountain biome where villages can generate. This biome usually generates in the lower sides of some mountains but can also generate standalone in plateaus, mainly next to plains and other temperate biomes.

Grove
The grove creates a forest of spruce trees on the sides of a mountain, reminiscent of a snowy taiga but the surface is covered with snow layers, snow blocks, dirt and a lot of powder snow instead of grass blocks. Rabbits, wolves and red foxes can spawn in this biome. This biome generates in high altitudes beneath the peaks and on hilltops next to forested biomes such as dark forests and taigas, and can generate as a large biome at lower altitudes if next to snowy biomes.

Grove use the same mob spawning chances as windswept hills for hostile and ambient categories. As for others:

Snowy slopes
The snowy slopes is a mostly barren biome covered in snow, multiple layers of snow blocks and powder snow, with some sides also having stone cliffs. Goats spawn in this biome alongside rabbits. This is the only mountain biome where igloos can generate. Just like the grove, this biome generates at the slopes of the mountain, beneath the peaks and in hilltops, usually in areas with less forested biomes, such as plains and snowy tundras, and can start generating at lower altitudes in snowy regions. Polar Bears can spawn in this biome.

Peaks
There are three peak biomes that generate only at the tops of the mountains, if they are tall enough to generate them, and are dependant on the surrounding biomes' temperatures.

Jagged peaks
The jagged peaks biome generates in regions with snowy, cold and temperate biomes and is more likely to generate in taller and more jagged and pointy peaks that often pass the clouds and can peak at y=264. Not all jagged peaks can pass the clouds as it just can be a big meadow hill or short mountain peak. It is covered by a single layer of snow blocks with stone underneath often exposing ores such as coal, iron and emerald, and just like the snowy slopes, stone cliffs can generate in some sides of the mountain. Only goats spawn in this biome.

$$, jagged peaks use the same mob spawning chances as snowy slopes for hostile and passive categories.

Frozen peaks
The frozen peaks are covered by snow, snow blocks, with glaciers of packed ice and occasional small blobs of ice. Only goats can spawn in this biome. This biome usually generates in smaller and smoother hills near snowy, cold and temperate biomes, but it can also generate in slightly jagged and taller peaks but less compared to the jagged peaks biome.

$$, frozen peaks use the same mob spawning chances as jagged peaks for passive category, and windswept hills for hostile and ambient category.

$$, frozen peaks use the same mob spawning chances as snowy slopes for hostile and passive categories.

Stony peaks
The stony peaks are a warmer variation of both the jagged peaks and the frozen peaks biomes that generates when a mountain peak is in a region with lukewarm biomes such as savannas and jungles, and it doesn't generate snowy slopes or groves in the slopes of the mountain, unless there's a colder biome bordering the peak. It is mainly covered by stone with large strips of calcite and exposed ores. The grass and foliage in this biome have a unique vibrant light green tint, similar to the tint of a shattered savanna in Bedrock Edition.

$$, stony peaks use the same mob spawning chances as jagged peaks for the hostile and ambient categories. No mobs spawn as part of the passive category.

$$, stony peaks use the same mob spawning chances as meadow for hostile category. As for others:
