The biggest salt lake in China, an
Chaerhan Salt Lake spreads over 5,800 square kilometres at 2,670 metres, holding enough sodium chloride to feed the entire world for 1,000 years. The 32-kilometre Wanzhang Salt Bridge is a highway with no piers and no concrete — it floats on brine, held up by nothing but crystallised salt. You can stand on a single crystal the size of your palm and it won't crack.
