The old survival lava islands i was able to dig up from an old page. Couldn't let it go.

Welcome to Survival Lava Islands

Welcome to Survival Lava Islands. This map is intended to be a more challenging version of the original Survival Island map with exploration being encouraged primarily on the surface of the map, rather than underground. This means you can enter and leave islands as you please; there are no rules aside from no leaving the map boundries into naturally generated terrain. (The Nether's allowed though.) The map contains no dead-zones where Monsters can spawn and waste spawn slots so expect to be swarmed by dozens of Creepers, mauled by packs of Zombies and be knocked into Lava by Spiders and Skeletons.
Special thanks to Tyken132 for the Lava Map.

I believe this is version 5.0 of the map which has no problem running on 1.1, but you can probably use it in later versions (Most features of new updates won't be present and/or something might break).

Credits go to the original creator "Kozoi", who apparently doesn't exist anymore.
