Expedition Behavior is something that can make or break a course. It can bring people together as a group and as a team, or it can completely tear it apart. According to Harvey (1999), NOLS Instructor and author, EB addresses basic human needs: The most basic human needs [are]…food, water, shelter, and feeling of security…After the basic needs of the human organism are met, good expedition behavior springs from all the most decent of human traits: respectfulness, flexibility, tolerance of others, courtesy, politeness, direct communication, self awareness, open-heartedness, teamwork, sharing, and selflessness (p. 166-167).
