I don't have time to upload the save right now, but here's the gist of it:
Part of my map is a glacier; obviously, it's all frozen. It has two z-levels of ice.
I tried collapsing the ice to produce water. This is how:
Level 0 (glacier surface):
=========
= =
= ===== =
= ===== =
^ ===== ^
= ===== =
= ===== =
= =
========== is ice floor (the glacial surface). Note the chunk in the middle has a perimeter dug out around it, so it can be collapsed. ^ are upward stairs (see next layer).
Level +1 (one above glacier surface):
+++++++
+ +
+ +
v+ +v
+ +
+ +
+++++++
+ is floors, built as scaffolding above the perimeter hole to block sunlight (although I was stupid and built most of it AFTER the perimeter was dug out). v is downward stairs, supporting this floor.
Levels -1 and -2 (ice layers):
*********
* *
* ***** *
* ***** *
* ***** *
* ***** *
* ***** *
* *
********** is ice walls. Again, perimeter dug out. Obviously, one tile was left until ready to collapse it entirely.
Level -3 (underneath ice layers):
ooooooooo
o+++++++o
o+++++++o
o+++++++o
o+++++++o
o+++++++o
o+++++++o
o+++++++o
oooooooooo are walls of various sorts and + is the natural floor here. This is the area for the ice to collapse into.
Now, those diagrams aren't COMPLETELY exact; I especially left off some access stairway or two, for instance. You'll see more when I upload the save.
Anyway, so I collapse this ice, and what did I get? One of the layers collapsed normally, I THINK, to some degree (it was slightly messy), which hilariously destroyed the floor of Level -3, resulting in microcline-colored "open space" where the floor was, with microcline walls being below on Level -4. Please note that this means the ice did not fall all the way down! I'm pretty sure some of it did, but damn near a whole layer stayed on -2.
But here's the hilarious bit: Level -1 had almost NO ICE WALLS AT ALL. Maybe one or two squares connected to the ones below?
So where did it go?
Easy.
Level +1 (one above glacier surface):
+++++++
+=====+
+=====+
v+=====+v
+=====+
+=====+
+++++++
Level 0 (glacier surface):
=========
= =
= ***** =
= ***** =
^ ***** ^
= ***** =
= ***** =
= =
=========
That's right. An entire layer of ice managed to jump UP and latch onto the scaffolding above. This diagram may also be slightly inaccurate; I think a few bits of ice were off to the sides of the main block too, in the perimeter area. Maybe.
My only possible explanation is that the solid ice didn't really move much or at all; rather, it turned into mist, which then resolidified, and mist liking to travel upwards, a lot of ice wound up getting higher than it was before.
