The ravine treasures of this seed lay deep down in the earth directly to the right of the spawn point. If you stand on the edge of the ravine to look down, you’ll see a tree and lapis lazuli at the bottom. That’s just a hint of what’s to come down in this ravine.
Minecraft PC 1.10.X Seed: 1011494625331452340
Finding lapis lazuli right off the bat is rare, but this ravine is deep enough that it allows you to do just that.
Though it’s probably the least of the things you can find in this ravine, the tree next to lapis lazuli gives you wood when you’re down there. This way you can make tools without hiking back to the surface after you’ve taken the perilous journey down the cliff.
For the rest of the ravine treasures on this seed, go into the hole below the tree. Continue down to the cave at -247 / 18 / 264. While the other caves may contain some iron and gold, they all ultimately lead to dead ends.
The Abandoned Mineshaft
As you go through this cave, you can pick up gold and redstone on your way. When you come to the circular room with lava, turn to the left and go through the tunnel with a waterfall flowing down into it.
Follow the tunnel until you see two planks of wood near the ceiling. That marks the beginning of the mineshaft.
You can explore the mineshaft to find chest minecarts containing rare items. You can find one early on at -240 / 25 / 209.
The Real Ravine Treasures: Diamonds
If you want to find diamonds quickly, go back out to the tunnel where you first saw the two wooden planks. Continue toward the glow of the lava that’s up near the ceiling. Around -253 / 22 / 214, there will be a hole in the ground with more lava glow.
Over the lava fall and past the lava pool, you’ll see three diamonds in the wall. Though the lava is intimidating, you can get rid of it with a couple buckets of water. You’ll find that there are actually six diamonds total to mine.
This seed makes it easy to get great ore and diamonds early on, and that’s just in one ravine. Continue to explore and see if you can find anything else exciting on this seed!
