Rock climber extraordinaire Lynn Hill is featured in a new Discovery Channel documentary Valley Uprising.
Hill earned the title of living legend in 1993 when she became the first person, male or female, to free climb what's known as the nose on El Capitan in Yosemite National Park.
Hill told INSIDE EDITION, "It had been an objective of so many people for so long, and it hadn't been done, and I was really proud to be a woman."
Climbing the cliff is no easy task. Hill explained, "It's glacial polished granite and the edges are very small. It requires a lot of coordination and strength."
More than 20 years later, there's only been one other person who's completed an all-free ascent of the nose in one day.
