Minecraft: Floating Peninsula

So in my Minecraft world, I have been mesmerised by a certain structure in the landscape.

That's the distant shot. Upon closer inspection...

Yeah. Pretty sweet, eh? Well, I took it upon myself to  sever it from that which it was connected. A floating island in the sky. Well, after a bit of doing so...

Yeah, that's only partway done. On the other side of that, behind me, is a wall. Like this.

I gotta dig through that. Well, actually, I succeeded in doing so.

I'm pretty proud of myself. I also had to light up basically everything underneath the island, because the shadow cast by it was so immense that it was essentially nighttime on the ground, and monsters were spawning like crazy. Trees couldn't grow, anything. It was cool, but annoying.

There's snow on top of it and everything. Now, what I should do is make a river flow off of the side of it closest to the water, so I can skyboat up to it. :D

Skyboat: (Verb) The action of abusing a glitch in Minecraft, allowing one to ride up a waterfall at extreme speeds while in a boat.
