The United Kingdom’s claim of sovereignty over the Falkland Islands was challenged by Argentina in 1982. When the latter seized the island, they covered the beaches with landmines. The war with Britain lasted less than a month, but the mine fields where left behind. Efforts to clear approximately 25,000 of the buried explosives began in 2009. According to legend, when a local man lost his leg from one of these mines, he impaled a boot on a hill near Port Stanley. In sympathy, others repeated the gesture on what is now called Boot Hill.
