Once upon a time there was a big coal mining town at Kadykchan, with almost 20,000 people living and working there. That all changed in late 1996, as winter was approaching. For reasons I don't fully understand (apparently to do with an accident in a coal mine) the authorities decided to abandon the town, overnight. To help people who didn't really want to move (most people) to make up their minds, they turned of the electricity and hot water (like all Russian cities, the hot water was provided by the city and piped to everyone's apartment). It being -40 ish outside at the time, the city of 16,000 was abandoned by the next day. It still stands now as an eerie ghost town, about 3km off the Road of Bones, immediately adjacent to where the old summer road thru Tomtor meets the maintained section.
