Island With 2 Ravines And Mineshaft
Minecraft Seed: 1528064087
This is a Large Biomes seed that drops you on a medium sized island with many trees. There is no land nearby (I quit looking because I couldn’t find any).
There is a ravine on the surface that also intersects a 2nd deeper ravine! This can easily bring you down to depth 24 right away. There’s also an entrance to an abandoned mineshaft for all kinds of treasure 😉
