This thesis begins with an overview of the history of rock climbing that presents the opportunity to evaluate rock climbing as a religion/religious act in Section 2. Then, Section 2 delves into alternative spaces where religion exists beyond mainstream institutions, in order to build upon some themes of religious experience to provide the context for a religion of rock climbing. Section 2 further investigates the extent to which these alternative spaces may maintain institutional constraints on par with religious dogma, and indeed may rest on the same assumptions and constraints found in the institutionalized religions. In Section 3, the question of institutional dogma in the rock-climbing religion is engaged by way of a critiquing the institutional modality of gender and sex discrimination in the climbing community. The thesis concludes that women rock climbers are constrained through institutional modalities that determine their experience of rock climbing according to sexist body-normativity. This ultimately negatively impacts their religious experiences of rock climbing.
