2016 Update: This original seed here was not working anymore due to a biome code update, so I updated it with a new snow and mountain biome seed thanks to MillaTheHound. Here's a Minecraft seed on the Xbox 360 with a Snow biome, ice plains, cold taiga, ice spikes, and mountains at spawn. There is also a flower forest, roofed forest, beaches, plains, forest, ocean, and a few other biomes in this seed!
The seed is: 59
