You will spawn in an NPC village, next to the jungle. Near the village there is a small crater, dig through the sand and you will find a dungeon with one chest.
But it gets better! You will notice there is another passage way connected to the dungeon, make you way through it and climb down the hole that is to the right of the lava. At the bottom, you will find a dungeon with not one, not two, but three chests!
This seed works for Minecraft 1.2.
