The Greenland case describes the experience of four young Norwegian men determined to set a world record for unsupported crossing of Greenland. The case describes the team, their preparations, and their experiences as they crossed in "good" weather that was often whiteout blizzard conditions with temperatures dropping as low as -78 degrees F. Throughout the case, one of the team members reflects on things he learned about himself, about the team, and about leadership from the experience (recorded in italics). The teaching note (available to registered faculty) is supplemented by a PowerPoint presentation that helps introduce the expedition to Greenland, other "risky recreation," and the concepts related to resonance or flow. A video supplement is also available. The case lends itself to a profound discussion of leadership on its own and leads in nicely to a discussion of world-class performance and the purpose of life, which both startles and pleasantly surprises most students and participants.
