This is Kiruna, a small northern Swedish mining community. The 18,000 residents here are facing a particular conundrum that has them —ahem —between a rock and a hard place. You see, their mining livelihood depends on the rich veins of iron ore dotting the area, but digging deeper tunnels to harvest more of that resource would essentially collapse their town by leaving the surface too unstable to support its buildings. So what did this community decide to do? Move down the road!
