After load the seed and at the spawn point, the extreme mountain, never close like that. Just turn around and you will see large mountains, overhangs, waterfall and more unatural stone. As the images below we trying to put some texture pack and it look like so cool, so you can try with other texture pack to make your own ways. This seed is one of the best extreme mountains seeds we have seen so far.
