This is a HUGE island I created as a fun map. It goes from bedrock to the height limit to create large mountains and fun cave systems. There is a huge ocean surrounding it as well, so you can add lots to this map without runing out of space. Think about the projects you could do with raised height limit (about 120 blocks high). You will have to look through it to see all the fun, but I'll give you a key piece of information right now. The only trees on the island are at the tallest peaks and you start at the bottom, so this should provide a bit of a challenge to even the most seasoned adventurer. There is no lava so I have provided a nether portal somewhere on the map. Have Fun!
