With their vertical aptitude, climbers go places few others can. Often that results in a first ascent, but, occasionally, it also leads to exciting new discoveries. That’s certainly the case with the expedition at the center of Namuli, a film named for the second-highest mountain in Mozambique. Climber Majka Burhardt (a guest at Mountainfilm in 2008 and 2010) became so obsessed with this peak that she assembled a team of athletes, scientists and community members to climb it in order to understand it better. In the process, they discover a bounty of unanticipated biodiversity and gain a better sense of why the region around this mountain deserves stronger conservation.
