Italy\u2019s alpine frontiers with Switzerland and Austria generally follows the watershed line. Thanks to climate change and shrinking glaciers, that line has been shifting, so Italy entered into agreements with Austria (in 2006) and Switzerland (in 2009) to redefine their borders as moving borders, shifting as the watershed line changes. (This is not something I would have expected: see, for example, U.S. state boundaries remaining where the Mississippi River <em>used to be<\/em>, rather than its present course). Italy\u2019s official maps are updated every two years. In 2014 and 2016 Italian Limes dropped solar-powered GPS sensors on the surface of a glacier to track the shifts in the border in real time; the accompanying art installations slash exhibitions allowed visitors to plot the border at that moment.
