Abstract

This is a story of what happened on the Aiguille du Grepon. It is based on fact and designed to reveal both the appearance and reality of motivation in climbing, a combination that is often difficult to express in a traditional academic style. The story differentiates motivation along two dimensions, a goal dimension with intrinsic and extrinsic rewards at opposite ends and a relational dimension with exclusive and inclusive rewards at opposite ends. These polar opposites are integrated in the experience of outdoor adventure through the story. They are further reflected in the attitudes of a previous generation of climbers. It is suggested that these motivations define the games of outdoor adventure in general, and that we should be self-conscious of them both in education and in play.
