Minecraft wiki entry for Best_biomes_for_homes, associated text: The mountains biomes is perhaps one of the most spectacular biomes, with peaks and stone cliffs, but also one of the most difficult to navigate. In mountains biomes, it is often better to build bases in the mountains, instead of on them. Large surface caves, floating mountains, and overhangs are often found. Snow falls above y-level 95, allowing for snow farms and ice farms in this biome.
