interesting/weird terrain generation

we all know that minecraft worlds in these older versions can get pretty wild, so i want to see the cool and crazy stuff your worlds have. i'll go first with some screenshots from my world.

(its sorta hard to see but thats a small bay back there surrounded by steep hills)

the last image is especially interesting to me because the floating island in the background has a natural stalactite, i almost cant believe that minecraft just did that on its own.
