Drawing from his frequent forays to Death Valley, Red Rock Canyon, Kelso Dunes, and other locales, the author illuminates the desert's intriguing flora and fauna as he explores a controversial, unresolved scientific debate about the origin and evolution of its unusual ecosystems. Eminent scientists and scholars appear throughout these pages, including maverick paleobiologist Daniel Axelrod, botanist Ledyard Stebbins, and naturalists Edmund Jaeger and Joseph Wood Krutch. Weaving together ecology, geology, natural history, and mythology in his characteristically eloquent voice, the author reveals that there is more to this starkly beautiful landscape than meets the eye.
