Just a nice little floating island, after all, we dont find one of those everyday (even if this extreme hills biome has many floating structures).

A little Valley just next to a Jungle biome. It looks like a very nice place where you could build a house.

I was acually going to put a location where there were 3 ravines one on top of the other, but while looking for that location this "transparent blocks" glitch revealed me something even better about this extreme hills biome... It has a stronghold underneath it! (digging straight down from the coordinates I gave will not get you inside the stronghold, you will get across the wall of it while mining straight down)
Note: This stronghold is enormous and HAS an End portal, many good chests and a library (thats all i could find)

What can i say about this.... its a really weird floating structure but, even though, cool looking.
