An aquifer is a subterranean layer of Template:L-bearing rock or Template:L. Attempts to mine through them will result in the mined-out squares immediately filling with Template:L, effectively halting excavation at or below their level. This, in conjunction with the fact that they are often located in areas rich in Template:L, and Template:L, makes it difficult to find great quantities of Template:L in areas with aquifers, making for more challenging gameplay.
Dealing with aquifers
The ore method
On maps where the aquifer is not held in a layer of soil, but instead is held in a sedimentary layer such as sandstone, it may be possible to tunnel down through deposits of ore such as magnetite. For this to work you have to find a spot where there is coincidentally an ore deposit on each Z-level you need to dig through. This is only possible through tiresome trial and error, or through the use of a utility like reveal.exe.
The magma/obsidian method
If you have access to a supply of magma, you can create your own obsidian caissons. By channeling into the aquifer layer and then filling these channels with magma, it is possible to create a wall of obsidian between your working area and the Template:L-bearing rock or Template:L. However, changes to world generation with the last version have made this method more difficult than it once was, as it is now harder to find magma vents that extend above the aquifer level.
