Both for sight-seeing and for tutorials, this is a wonderful new book. It illustrates a great many important geological principles while providing glorious sights to see. Almost all of the sites can been visited by road. You'll find many settings of igneous, sedimentary, and metamorphic rocks (JIR spoofs those as ingenious, sentimental, and metaphoric).
Each selection has a 2-page spread: the left side tells coordinates, background, and what you can see. The right side presents 3 or 4 photos, cross-sections, maps, and/or development sequences. As in most cases where a publisher or designer dictates that all selections get equal space, both stories and typography may seem puffed or crammed.
Many places are within a half-day drive for most Americans. There's at least one in every state - one of the selection criteria. Just as in baseball's All-Star Game, where there has to be a player from every team, this promotes a number of less-important selections at the expense of better ones. Baseball depends on its fan-base, but people seeking superior geologic examples know perfectly well that they have to travel to see most of them. I hope the next edition abandons this criterion. Travelers will find concentrations of gem-quality sites easier to take in during reasonable excursions.
The author's illustrations and points are extremely clear. I found no typos, and only 5 minor mistakes.
The glossary, references, and index all have lots of entries, enabling a reader to pursue items. The glossary is a bit terse considering that many readers are novices. But it does distinguish, for example, between "terrain" ("A region of the Earth that is considered a physical feature, such as the Great Plains") and "terrane" ("A body of rock bounded by faults and characterized by a geologic history that differs from adjacent terranes"). It would be improved by listing all the examples in the book. The index probably doesn't list all occurrences of each term.
Whether you seek the newest or oldest rocks, or relics of ancient Gondwanaland or Rodinia, this book shows the way. These 101 geo-sites are well worth the trip for anyone interested in the more durable parts of Nature.
