This is a Minecraft 1.2 seed, so it works on MCPE, Xbox and Windows 10! (read more)
Watch the video above to find the ravines and the mineshaft!
This seed has 4 ravines, one of them has a mineshaft connected to it! Mineshafts just got added in Minecraft 1.2 update, at least to Pocket Edition. I am not sure if Xbox had them already.
The spawn is really cool - you spawn on an island with a ravine! Even if you don't want to find the other 3 ravines and the mineshaft, you can start playing some survival island playthrough with this seed!
That's what the mineshaft looks like inside the ravine! There's a lot of chests, so you will have some amazing loot after exploring it. Be careful though, there's a lot of monster spawners too with some cave spiders!
