Mark Synnott has traveled to Greenland, Russia, Patagonia and Nepal, among others, to find unclimbed rock faces to scale, and he’s made first ascents of some of the world’s tallest walls. He also uses his expeditions to search for and gather information about rare species living in what would otherwise be inaccessible locations. He’ll talk about his adventures while sharing photos and videos in this presentation.
