Rock Climbing in Yosemite National Park

"The Dawn Wall" is a documentary film that shows how Tommy Caldwell and Kevin Jorgeson managed to climb El Capitan's southeastern face, called "The Dawn Wall" in Yosemite National Park, California.  It took them 19 days to go up the vertical granite, and six or seven years to prepare that remarkable feat.  "It's highly precise" Jorgeson says of the preparations and he compares the moves across the rock to a dance choreography or to a gymnastics routine in this NPR interview.

The beginning of the interview contains some technical descriptions of the climbing equipment, so this 31':49" interview could be classified as C2.
