Dismissed by the first Spanish explorers as a wasteland, the Grand Canyon lay virtually unnoticed for three centuries until nineteenth- century America rediscovered it and seized it as a national emblem. This extraordinary work of intellectual and environmental history tells two tales of the Canyon: the discovery and exploration of the physical Canyon and the invention and evolution of the cultural Canyon—how we learned to endow it with mythic significance.Acclaimed historian Stephen Pyne examines the major shifts in Western attitudes toward nature, and recounts the achievements of explorers, geologists, artists, and writers, from John Wesley Powell to Wallace Stegner, and how they transformed the Canyon into a fixture of national identity. This groundbreaking book takes us on a completely original journey through the Canyon toward a new understanding of its niche in the American psyche, a journey that mirrors the making of the nation itself.
