Kufu's pyramid UPSIDE DOWN on the top of the pillar. Complete with Gold Cap.

Properly dwarven open pit mining involves mining it all out, channeling out the edges, and pulling a lever to simultaneously deconstruct all supports.

And then making a sandwich while your frames are resolving. Or perhaps a 9 course meal.

If the hollow tube does not extend to the lower pair, then you could manage to acquire another four squares of candy. However, the only way to know is to Reveal or save scum.

Or just have Derm standing by.

Trap door quantum stockpile. Channel floor. On upper level, lay hatches. Lay stockpile on upper and lower levels. Connect doors to repeater. Food is stockpiled, and dropped to lower level. Hatches close, process repeats.

My current moat is actually filled by pumps dragging water up from the aquifer.

Channel from above. Dig your trench, two levels tall, and at the bottom of the top level, and then channel out off to the side. It's technically possible to channel out from a level you haven't mined.

This is why I learned my lesson. Flood gates exist for a good reason. (To drown elves with magma.) But also too dam water out of moats so stupid Dwarves don't die.
