Just how to locate lava in Dwarf Fortress
What's an excellent way to locate lava in Dwarf Fortress v0.31.08 (or thereabouts)? (Ideally without disloyalty.) I recognize if I dig right down I'll at some point locate some, yet I generally end up burglarizing a below ground cavern with hostile animals and also I would certainly such as to stay clear of that. Additionally, I would certainly like it to be a little closer to the surface area so I do not need to construct some sort of hugely huge pump pile to relocate the lava approximately a valuable degree.
Should magma similar to this be readily available on the majority of maps or is it very depending on get started area? Should I look 20 degrees down and also dig a grid? 40 degrees?
