Minecraft 1.8.3 hills seed by mesa and forest with spruce trees
Here's a Minecraft 1.8.3 hill seed with a bunch of extreme hills and mountains at the starting location, and some sheep. There's also a mesa in plain sight of the starting location, but over the first mountain of course.
The seed is: 6400955617174250422
This seed has a spruce tree forest at the start as well, on top of all those cool snow covered mountains. This is a fun Minecraft 1.8.3 seed, and there's also normal forest nearby for a more generic Minecraft experience. Why settle for anything short of awesome, like this one of many diverse and cool Minecraft seeds.
