In 2000, Mark travelled along with his friend Bruce Parry for 77 days to climb Puncak Mandala in the Indonesian part of New Guinea. This is the third highest mountain of Australasia, but is little known and rarely climbed (their ascent probably being only the third one). During the expedition, the team had first contact with some members of the Korowai tribe. In the course of the expedition, the adventure documentary, Extreme Lives: Cannibals and Crampons. was co-directed and written along with Bruce Parry. The film won both the Banff Mountain Film Festival and Kendal Mountain Film Festival.
