Any custom-made terrains out there available for sharing?

In the terrain generator, I've made a few free play parks using the existing tools for land/water depth and frequencies for randomness of number of and severity of hills, etc. I've been trying to go beyond these by creating winding rivers and/or mountains/cliffs and I'm just not happy with my results. I was wondering if anyone out there has some built some creative custom terrain that they'd be willing to share for my personal use in free play. Thanks all!
