From part of a larger National Geographic project comes this little gem of a clip. The 48-minute-long documentary The Man Who Can Fly follows world-renowned rock climber, slack liner, and BASE jumper Dean Potter as he embarks on another extreme excursion. In the clip from the documentary below, Potter walks a highline between the rocks at Cathedral Peak, California. The footage was shot from over a mile away by Michael Schaefer.
