Ant, Jon - that all makes some kind of sense.

I'm sure it'll all become more apparent in game.

I told you, it's not an ugly hole!

I plan to build something big. 120 blocks high, double real life scale. I'm thinking now though that maybe I should do it 1:1 so there's hardly any digging. Or one of each maybe.

Oohh, yay, thank you :D There are some chests right next to the hole which might have some iron tools in, and possibly some iron ore. Haven't got any diamonds though.

I have drawn a square around the area that needs clearing but I think it needs moving up (on the dynamic map) 5 or 6 blocks.

I'm also gonna have fun finding the materials to build what I want. I think a large part of it can be made from dirt (orange wool would be better though) but need to find lots of white and black. I started to build one part from dirt, gravel and sand to see what it looks like and its huuuuuge.

It's north of that on the sand. It shows up as a black hole with a dirt square around it and a round thing in it.

Ant: Nope, much more fun than that.
