For the first time in known history, a human being has sailed the seas, trekked the jungles, and skied both poles to circumnavigate the entire globe north to south, and back north.
The man who has perhaps seen more of Earth than any human alive just completed what might be one of the greatest expeditions ever attempted.
Last week, renowned explorer Mike Horn completed his epic 3-year Pole2Pole voyage, traversing the entire globe longitudinally. That included two pole crossings, one of which saw Horn become the first person to ski across Antarctica at its widest point unsupported.
The 53-year-old South African even added a stop in Pakistan to Summit K2 along the way.
