Minecraft wiki entry for Soul_Sand_Valley, associated text: The soul sand valley is mostly composed of soul sand and soul soil, with gravel found on its coastlines. Soul fire is scattered throughout the valley and nether fossils poke out of the terrain. It lacks a diverse set of plants, with the only native vegetation being crimson roots and mushrooms, although fungi, nether sprouts, various roots and huge fungi may spawn where the valley borders a crimson forest or warped forest. Its fog is cyan and the air particles are gray as the sounds of winds and the voices of ghosts fill the air. Giant columns of basalt called basalt pillars can be found stretching from the floor to the ceiling. Caverns, fortresses and even bastions can also be found in the soul sand valley.
