Utterly Mad

And here I was thinking "no aquifer, race to the cavern".

Aquifer is probably much smarter and more interesting, but I have no idea how to breach one in new DF in the desert. Usually, I just self-drain them, or collapse them, but don't know if either work anymore. My only aquifer start since .40d was in one of my few 2010 games, and I started *beneath* it somehow. So that would be a problem for someone else.
