20 Days Across Canadian Wilderness

On Friday, two decorated adventurers will set out to cross country ski for 20 days and 150 miles through the Canadian wilderness. During the 2008 Canadian Arctic Trek for Earth Health, Ed Viesturs and John Stetson plan to get a close-up look at look at how global warming is reshaping the Arctic and the lives of the Inuit people.

The team will post daily updates edviesturs.com.

The dedicated earth-conscious athletes - Stetson is a veteran sled dog musher and Viesturs recently became the first American to ascend the world’s 14 tallest mountains without supplemental oxygen - hope the trek will focus attention on the interconnectedness of life on earth. "We live in a fish bowl," Viesturs says. "And we need to keep our little home clean."
