Tommy Caldwell and Kevin Jorgeson recently became the first rock climbers to complete a free ascent of The Dawn Wall on El Capitan in Yosemite.
You can see a dizzying visual representation here at the New York Times. Their feat was the most difficult climb ever completed, by some estimates.
And one of those guys was missing a finger.
"I totally didn't notice but several people pointed this out on Twitter: Caldwell only has 4 fingers on his left hand," writes Kottke.
"He cut off his index finger with a table saw, got it reattached, and then removed again so it wouldn't hinder his climbing."
