cliffail

I tried the Glacier seed with the 1.8 update and it still pretty awesome!
I've made several homes in this world because I frequently get lost, but there is a massive cave/mine-shaft network close to the small outpost with melon's growing outside, and there is a huge cliff range not too far away either.
You can just about see the mountain range in the top right hand corner of the map where it's partially loaded. Download this just to get a look at it, it's unreal!
