I was looking for a random world to start a survival game in. When the world was generated, I found a bit weird for me to have spawned in a snow biome (usually spawn in a forest). I started walking around wondering how big this place was. The more I looked around, the more I realized this world may actually be just one big biome. With that thought in my mind, I turned on creative mode and started flying around with a map. The entire map seemed to be just snow. I even went out past the paper map's boundaries and still found more and more snow. Anyone who's looking for an endless snow biome, you have found it.
