Wife of El Capitan climber awaits husband's ascent to top

YOSEMITE NATIONAL PARK, Calif. -- Rebecca Caldwell, wife of Tommy Caldwell, said she is anxiously awaiting her husband's goal of reaching the top of El Capitan in Yosemite National Park during his attempt to free climb the Dawn Wall.

"It's going to be emotional," she said. "It's going to be a really special moment."

Caldwell has a blog where she's been documenting her and her husband's climbing adventures.

Caldwell said she was surprised by the amount of attention the climb has gotten.

"We did not expect people to latch on to this," she said. "It's exciting because it's more than just a climb. It's deeper than that. It speaks to what's human in all of us and what we can all relate to."
