Minecraft Seed: -7555088704316963702
The seed has a total of 5 ravines. You spawn not too far from a waterfall. If you head towards the waterfall there is a cave, or if you head right from the spawn point towards the trees there is a small cave that hides 3 ravines. Down in the cave near the waterfall if you follow it down and around, at the end, dig around till you hit gravel and continue a few blocks and it will open up. Then go away from the waterfall and follow it around. Go right when it splits off and you should find a lava fall. On your immediate left there will be the zombie dungeon 🙂
In total, its lapiz, diamond, redstone, obsidian, iron, gold, A LOT OF SHEEP, coal and everything else in between (except Emerald). It’s a lot of fun. 🙂 GOOD LUCK!
