Originally an aboriginal trade route, the road now known as the Oodnadatta Track stretches roughly 400 miles through the Australian Outback, snaking past hills, ruins, and barren stretches of moonscape once prowled by the Humungus in Mad Max. In 2013, Oodnadatta got so hot that meteorologists had to add a new color to their heat maps and motorists were forced to stay put when temperatures soared to the point that gasoline was evaporating before it could hit their gas tanks.
