i know, and everyhting i've had dumped has gone off the side of the mountain, into one single space, most of it is rock but lots of other stuff too, is there any other way other than dumping?
You can make blocks (which fit into bins, but can't be used for all of the same things), dump the stone (a 1x1 space, out of sight, out of mind, can be managed from the stocks screen), hide the stone from sight (it's still there, but hidden from your view), atom smash it out of existence with a drawbridge (it is removed permanently from the game).
I
think that's everything, except
magma, of course.
I prefer to just ignore the clutter while otherwise useless dwarves make blocks on repeat to train an army of highly skilled masons. The blocks go in bins and out of sight, and are later used to build outlying fortifications, workshops, and machines. This increases fortress wealth, which I counteract by using dumps early on (smallest space, allows me to place the destination) and subsequently reclaim (and use as block material) for training later. Putting masons/mechanics/stonecrafter workshops near the bottom of the shaft I drop the stone down was a convenient way to make dumping work much better for me. Then there's no wasted effort, as dumped stone isn't being tossed into a useless out-of-the-way spot, but right where it's going to get used later.
Rather than reclaiming with the d-b-c method, using the stocks screen can keep you from accidentally reclaiming corpses and body parts you're dumping. (I also use this method for bones and skulls, and it's convenient for items to be melted down, as well.)
