Don't overthink this one. The song Town With No Cheer on this album is about a town in Australia, and so is this one. Coober Pedy. It's an opal mining town. The houses there are built underground because of the scorching heat, and there's even an underground shopping center. There's literally a world going on underground in Coober Pedy. The big black bones rattling around in the danger zone could be dynamite or explosive charges, miners tools, maybe even railcars carrying sedimentary rocks out of the mine for processing or the rocks themselves. Being on the other side of the globe, the people there are literally awake while the rest of the world (or at least half of it) is asleep.
