Minecraft wiki entry for Mountains, associated text: 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.
