I was exploring for the amazing update that was just released and I happened to be looking for a lush cave. I came across one at 11330/134/-93738, when I noticed some snow. After following the snow in spectator mode, I wondered why there was snow, so I used the debug menu to find out what biome the game thought I was in. It turns out, it generated snow below an above grove biome. Near that snow shown in the picture, you will find a small jagged peaks biome, which is weird. I think that a mountain may have generated under a mountain, but I don't know for sure.

If this is intentional, let me know.
