Hmm. I'm not exactly sure what it was. 35x35 sounds about right. I just walked it off without measuring
It yielded a ton of cobblestone for us though
And took a freakin' long time!
Got about 3/4 of the way down til I discovered dynamite. :lol: I then discovered that it doesn't give you all the resources as if you mined :x
Our map has since been reset, and we now have a snow world! :roll:
I'm def. gonna have to hop in your guys' server and check things out.
