National Geographic Live: Mark Synnott, Life on the Vertical

A big wall rock-climber of the highest order, he’s made legendary first ascents of some of the world’s tallest, most forbidding walls, from Baffin Island to Pakistan. Mark has climbed Yosemite’s El Capitan 24 times, including several one-day ascents. Today, he uses his skills to break scientific ground, reaching incredibly inaccessible environments in search of rare species.

It’s all in the spirit of adventure and exploration in order to educate about these sites of strange, remote beauty. Synnott has been a contributor for both National Geographic Television and National Geographic Magazine since 1998.
