This is a great account of the eminent evolutionary biologist George Gaylord Simpson's expedition to southern Argentina in the 1930s. Before I read it, I thought this book might get bogged down in detailed descriptions of the fossils that Simpson and collegues were digging out of the Argentine soil. Instead, it turned out to be a wonderful account of the culture and characters of the people there and the magnificent scenery he encountered. While a little bit dated in some ways, I highly recommend it as a travelogue, not just an account of a scintific expedition. Check out the reviews this book gets from Amazon.com and other sources!
