I was digging a stairway down, and the game said I found a magma pipe... Okay. Do I expand around my stairs and find Obsidian! Yay! Wait... White sand and Obsidian? So, I apperently found a Magma Pipe and an Aquifer 4 blocks from eachother... Is that normal?

[Jackrabbit]

Basically, yes. Have fun! Obsidian factory, here we go!

[Soadreqm]

Yeah, aquifers don't really make any sense at the moment. And neither do magma pipes. They happen right next to each other whenever a magma pipe is generated in a biome with an aquifer. You can use the pipe for getting past the aquifer, if it goes high enough and you happen to have a map with no other path.

I once got bottomless-pit + Aquifer...

I when I embarked I thought I'd a big natural waterfall as the aquifer drained into the pit...

But it didn't so I was sad.

Dwarven Engineering solves all your problems, and then makes them come back twice as bad.
On the bright side, you can first dig out your city lining the pit before activating the waterfalls.

Rest assured that if I didn't love my current quote so much this would be my new sig. It is so absolutely true.

Basically, if a magma pipe goes up through a layer with an aquifer, the aquifer will be "dry" a certain radius from the magma pipe. Also, obsidian will replace the border of the pipe, although some of the regular soil around it can be aquifer-free too.

What i would like to know is what happens if I:
-Channel out a 3x3 square of aquifer
-Run magma over it, makeing a 3x3 square of obsidian at the aquifer level.
-dig a staircase in the central square.

Sensible it would be if it stays dry, but this is DF. Has anyone tried this?

why didn't you just manufacture one ?
only a few channels would have been needed


such a kind of forst would give a whole new twist to the chasm challenge that we had ages ago

This is actually one of the well-known methods for piercing aquifers.

Aww, crud. That's no fun.

Obsidian is always the border of the pipe.

[G-Flex]

I know. I meant it replaces whatever rock/soil would normally be there.

[Tormy]

Yeah this can happen in DF...I am not sure that this can happen or not on our planet [real life] however.

[Yanlin]

Well, it's like the glue inside the tube. Except that it does get stuck to the sides even without oxygen exposure.
