Windswept Hills

Windswept Hills are uncommon cold biomes. There are three variants in the biome family.‌

Description
Windswept hills biomes feature steep terrain and reach higher elevations than any other biome in the game other than the windswept savanna biomes. The grass and leaves are an aqua color. The surface can be grassy, rocky and gravelly, snowy or icy, with many blobs and veins of ores and those are the only biomes, besides mountain biomes, where emerald ore is found. The cliffs of the windswept hills generally peak at roughly Y-level 140. There are stony areas below the sea level where infested blocks with silverfish can be generated, even below the deepslate layer.

Windswept hills 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 springs and lavafalls). This can create some impressive views at times. These oddities may be magnified in windswept savannas.

Survival in windswept hills 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 windswept hills, 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 windswept hills, 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 hills. Water can also be used to collect snowballs from the hills if snow generates there.

They mostly generate within clusters of temperate and cold biomes, commonly found next to taiga, forest and plains. Oak trees occasionally generate in place of some spruce trees. Llamas can spawn in these biomes.

The exact height at which rain ends and snow starts is randomized and used to be 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.

Variants
There are three windswept hills variants.

Windswept Hills
The windswept hills biome is the normal variant. This biome features the standard stony and grassy terrain, with a bit of tall grass and sporadically generated oak and spruce trees. 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. They are one of the two places where llamas can spawn, the other place being savanna biomes.

Windswept Forest
The windswept forest variant generates groves of oak and spruce trees. This variant does not feature the stony terrain so that the tall grass and trees can generate more often. This biome also generates standalone as a thick separation when a desert is bordering a snowy plains or snowy taiga 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 tall hill that borders a river or another low-elevation biome.

The windswept forest use the same mob spawning chances as the windswept hills.

Windswept Gravelly Hills
The windswept 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. Windswept gravelly hills use the same mob spawning chances as the windswept hills.
