Super Volcano
The Ticking Bomb Beneath Yellowstone National Park
If you know nothing about volcanoes, plate tectonics, or geologic history, then this book is a reasonable, basic, and accessible introduction. The author leans toward verbosity and is a bit florid, but not excessively so. But if you are interested in the geology of Yellowstone Park then there are better places to look.
The sub-title is "The Ticking Time Bomb Beneath Yellowstone National Park". This is why I bought this book and why I was disappointed. Only one chapter (less than 25%) deals with the relevant geology and that at a very low level. One chapter concentrates on the human history of Yellowstone where the geology is incidental. There is an overlong chapter on the history of plate tectonics and the rest of the book, by far the majority, is simply a catalog of volcanic eruptions through history (and even at that he misses Novarupta, AK in 1912, the biggest of the 20th century and Mt. Etna, Sicily, in eruption since 2001). The volume of ash and magma, the number of casualties, and social affects are reported in great detail. This is not uninteresting in itself, but is hardly geology. The attitude throughout is rather 'Gee Whiz' than scientific. In fact there is very little science in the book at all. There is not a diagram of a typical volcano let alone a super volcano. There is little about the mechanism of geysers and even less on fumaroles. And, in fact, he uses a rather limited definition for 'caldera'. This makes for a nice campfire story but is not very enlightening.
On top of that the book loses a star for design. It has a plethora of the annoying insertions so prevalent in magazines; a sentence of two from the text is enclosed in a box and scattered at random throughout. These are even more distracting in a book than they are in a magazine article. They add nothing to the text, they breakup continuity and they take up space.
If you are after human history of volcanic activity then you will get it here, if a little redundant. If, like me, you are looking for a scientific explanation, or, at least, a description of Yellowstone geology it is not here.
I have no doubt that the author's travel writing is very good; he should stick to that.
