Intrepid Explorers

Here's a slide show of the Top 10 Intrepid Explorers of All Time.

Included:

Leif Ericsson
Sacagawea
Christopher Columbus
Amerigo Vespucci
James Cook
William Beebe
Chuck Yeager
Louise Arner Boyd
Yuri Gagarin
Anousheh Ansari

I think it's a little heavy on space exploration not to include anybody who walked on the Moon. Where's Richard Halliburton, you might well ask. How about Thor Heyerdahl? The Arctic explorers get short shrift. I guess everybody would have a different top 10 list.
