So after loading a new map for 1.8 I found a desert. In the desert is a few spots where there is no sand but a blank stone face with assorted dirt, coal, etc. There is sand nearby and it gradually drops to this spot. The average height of these are y = 66. Is this just a feature of the desert biome or do others have this feature too?
Also you can see it across the river in my forest biome.
