    Iron ore becomes increasingly more likely to spawn between Y=-24 and Y=56 as you approach Y=16. As a result, for many biomes, iron has the highest odds of spawning at Y=16. Mountains, however, throw us a curveball. If you can manage to find somewhere on the map with mountains high enough, iron ore has the highest possible chance to spawn around ...
