   The highest peak outside Asia, it can be hiked to the summit without ropes, yet thin air still kills climbers.

   It is so wide that the cooler north rim and warmer south rim have noticeably different plants and wildlife.

   It was once so polluted that 1858's 'Great Stink' forced Parliament to finally build London's sewers.

   Stretched out, Norway is so long that its northern tip is closer to the North Pole than to its own southern coast.
