     Ed Viesturs grew up in Rockford,Illinois,where the tallest thing on the horizon was the water tower.But

on Thursday,Viesturs became the only American to climb to the top of the world's 14 highest mountains.

     His last hike was up Mount Annapurna,in Asia's snowcapped Himalayas.At 26,545 feet,its peak is the

10th highest in the world,It is the mountain that inspired him to start climbing.

     "It tends to be the trickiest,the most dangerous,"said Viesturs."There's no simple way to climb it.There

are threatening avalanches(雪崩)and ice falls that protect the mountain."

     In high school,Viesturs read French climber Maurice Herzog's tale of climbing the icy Annapurna.

Herzog's story was of frostbite(冻伤)and difficulty and neardeath experiences.Viesturs was hooked right

away.

     Viesturs got his start on Washington's Mount Rainier in 1977,guiding hikes in the summer.Fifteen years

ago,he set out to walk up to the world's highest peaks.Finally,he's done.

     The pioneering climber talks about mountains as if they were living creatures that should be treated with

respect."You have to use all of your senses,all of your abilities to see if the mountain will let you climb it,

"said Viesturs."If we have the patience and the respect,and if we're here at the right time,under the right 

circumstances,they allow us to go up,and allow us to come down."

     What's next for a man who can't stop climbing?"I'm going to hug my wife and kids and kind of kick

back and enjoy the summer,"says Viesturs.But for a man who's climbed the world's 14 tallest mountains,

he will probably soon set off on yet another adventure.
