Book excerpt: Offering a critical analysis of Smithson's view of time, it provides comprehensive case studies of three of his most influential projects: "The Monuments of Passaic," a sardonic tour of a decaying New Jersey city conducted in the wake of the passage of the National Historic Preservation Act; "Incidents of Mirror-Travel in the Yucatan," a textual-sculptural-photographic travelogue that coincided with a series of revolutionary discoveries about Maya history; and the Spiral Jetty."--BOOK JACKET.
