Ravine at spawn: -1775820978
Ravine is a new type of randomly generated landscape, which can be useful to the player because of resources that can be found there. Unfortunately, these are pretty rare, but using the right seed you can reach into it right away. Ravines are very steep and the hardest thing about it is to get to the bottom, but here you can use waterfalls to accomplish that.
