Book excerpt: Sherpas are portrayed by Westerners as heroic mountain guides, or "tigers of the snow," as Buddhist adepts, and as a people in touch with intimate ways of life that seem no longer available in the Western world. In this book, Vincanne Adams explores how attempts to characterize an "authentic" Sherpa are complicated by Western fascination with Sherpas and by the Sherpas' desires to live up to Western portrayals of them. Noting that diplomatic aides at world summit meetings go by the name "Sherpa," as do a van in the U.K. built for rough terrain and a software product from Silicon Valley, Adams examines the "authenticating" effects of this mobile signifier on a community of Himalayan Sherpas who live at the base of Mount Everest, Nepal, and its "deauthenticating" effects on anthropological representation. This book speaks not only to anthropologists concerned with ethnographic portrayals of Otherness but also to those working in cultural studies who are concerned with ethnographically grounded analyses of representations. Throughout Adams illustrates how one might undertake an ethnography of transnationally produced subjects by using the notion of "virtual" identities. In a manner informed by both Buddhism and shamanism, virtual Sherpas are always both real and distilled reflections of the desires that produce them.
