A rare biome consisting of hardened clay, stained clay, and dead bushes – similar to a desert. Red sand will also generate here instead of regular sand, with occasional cacti. Its composition is useful when other sources of clay are scarce. However, finding mesa biomes can be difficult due to their rarity. On the other hand, it offers great variety - there are a total of six variations of this biome to explore. Mesas can contain above ground abandoned mineshafts. They also allow gold ore to generate near surface levels, rather than just at layer 32 and below.
