Today i found a site with almost every feature, including:
HFS
Brook
UG River
Chasm (if you expand a tiny bit)
Magma Pipe
UG Pool
Flux
A few pictures of the site first.
My problem with the dwarf heaven site was that it didn't have any sedimentary layers, and therefore no bauxite. This site has a sedimentary layer, and hopefully bauxite, as it can be contained in any sedimentary layer.

That's right I generated this with standard "smaller" parameters, I believe that is everything, and just to let you know, I am running vanilla DF here.
Really, who needs magma pools when you have magma pipes? Or aquifers when you have other water sources, and ones that DON'T prevent you from digging.
Have fun on this (Almost) Perfect site!
