Minecraft wiki entry for Mountains, associated text: 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. ‌[BE only]
