Incredibly Dirty Slopes

So I was interested in seeing the new, less dirty slopes of Snapshot 4, but was incredibly disappointed, because just as soon as I joined the world, with a random seed (1093385784098641064), it was the most dirty slope I've ever seen in Minecraft. I was just posting this to let the devs know. I know it's not actually a snowy peak, like the changelog said, but it would be really cool if the devs added that smoothness to the other snowy biomes.
