Yosemite climbers reflect on historic ascent

They said it couldn't be done, but as we saw last night, two men reached the top of the rock formation known as El Capitan using only their hands and feet. Well, there's a lot more to the story. John Blackstone got to the bottom of it. After 19 days clinging to the 3,000 foot granite wall, Tommy Caldwell and Kevin Jorgensen were able to just walk the last few feet to the cheers of friends and family. Although we're very dirty and quite smelly. All I wanted to do is just wrap myself around my wife and hold my little kid. Today, their calloused fingers were still sore and Caldwell's voice was gone. As they challenged the wall, photographers hung on ropes nearby and crowds watched through long lenses from the meadow below. But the struggle was theirs alone. When you're in the moment and you're climbing those pitches, it's just... It's as solitary as you can get. It's just you and the moves. You seem to be defying gravity. That's what we do up there, I guess. You know, it's dead vertical in a lot of places. You can get away with standing on and hanging on to very small holds. So it creates really cool technical terrain that you can choreograph or navigate. We've seen those falls. What is that like? Is that frightening? A lot of times I feel like when I start to fall, my mind is still doing the move. It's like there's like a lag to the fact that I'm actually falling. And then you're on the end of the rope and you have to try again. The crowd watching from below were just small dots. But two of those dots were Caldwell's wife, Becca, and their son, Fitz. Becca said to me that she thought sometimes you're more comfortable hanging off a mountain than you are on flat ground. I'm pretty comfortable up there. And pretty much in all of the rest of life, I'm super clumsy. I'm not very smart. You're super clumsy? I'm not very smart. I forget stuff all the time. But on the wall? Yeah, it all comes together. Over the last 19 days, it all came together to make rock climbing history. John Blackstone, CBS News, Yosemite National Park.
