In 1995 one of history's greatest explorers, Reinhold Messner,
set out to cross the Arctic Ocean by sled. He went 11 miles
before turning back. Next month Ben Saunders (left), a
26-year-old adventurer from Devon, England, will attempt to ski,
walk and swim, alone and unsupported, 1,240 miles over the North
Pole from Russia to Canada--the same route Messner chose. Says
Saunders, a veteran of two polar expeditions who plans to haul
his gear in a 250-pound sledge, "I'd like to think that I'm at
the edge of what's possible." --Julia Morrill
