William Least Heat-Moon is a travel writer whose Blue Highways (1982) spent 42 weeks on The New York Times bestseller list. His following works, PrairyErth (1999) and River Horse (2002), created a trilogy that established him as one of America’s preeminent travelogists. His “deep map” approach is an intensively topographical method of writing a sense of place which interlaces the travel documentary with autobiography, archeology, folklore, memory, natural history, reportage, and interviews.
