That's where it is.

you have to upload it to an image hosting website (like imgur.com) and then give us the direct image link from that

Imgur and most of other image hosting sites are inaccessible from where I am.

You can make caverns like these fairly reliably by setting numbers in advanced worldgen for "openness 0, density 0"  or a bit higher on openness like 30 maybe.
Those parameters SOUND like you'd have a cramped little cavern, but in actual fact, you still end up with big open cavern. If openness is 50 it's still all one huge room or two, but tends to be a bit shallower. Setting openness a little lower, like 30 will still leave just a handful of huge nodes that go much deeper, and openness of 0 gives you more like large tunnels and smaller nodes, but still cavernous as long as density if 0, still large enough to build cool things in, and they will tend to be very deep.

If you want cool cliff dwellings, go for the 0 openness.  If you want a good chance of a straight drop for maximum distance, go for more like 30 openness.

You can think of it sort of like "the cavern has a certain amount of volume of tiles it takes up at a given density value, and the less open it is, the more it has to twist around and go vertically to meet its quota, so it goes deeper, but if it is too twisty, you won't have straight lines that go deep, even if the whole system does"


Similarly, if you want huge uniform expanses of unbroken rock, try to embark on a granite-likely area, and set advanced worldgen to have a very deep "above layer 3" or 4.

That's interesting mechanism!

Thanks, I like tinkering with the advanced world gen so this is very useful information. I currently have a rather deep third cavern myself, although it's nowhere near 80 Z levels. It's more like a couple of dozen deep but it has cool cliff-side shelves protruding from the walls which is kinda neat. Aside for that one cool deep sub cavern the layout under my current fortress is an absolute flooded mess of spaghetti. I think it might be part of the reason I don't seem to be getting FBs.

Man I just had the opposite experience. I had the magma sea at like 90z and the surface of the tundra is 114z.... Everything is smooshed together.

That ought to work for you.

Thank you very much!

I guess there was a hell of a lot of space...in hell.
