I'll try to get you all something more cohesive to look at soon.
I'll wait until I see a better sketch, I'm not sure exactly what you are doing with the above sketch.

Edit: While I was waiting I added a "side" view of the ERC area. To explain: The top right is the cone (link-in) and the Museum (just a rough sketch, I know we haven't decided what the museum will actually look like so I put in the original). Then the path from the cone, past a Japanese garden, through some statuary, and then down to the gazebo (which I did stylize in a Japanese style, it can be larger or smaller, can also add benches, bushes, so forth). Then we have the jungle surrounding the ERC and the valley beyond.
So, that is the picture I have floating around in my head.
