Annals of the former world is an omnibus of McPhee's writing on North American geology. It includes four of his previous books plus an extended coda relating to the mid-continent geology. He writes well, and engagingly, although the continuing immersion in hard-science geology proves a bit much for one book. As a result I read the first two books included, Basin and Range and also In Suspect Terrain, as well as the coda, Crossing the Craton. I will hold off and read the two remaining books, Rising From the Plains, and Assembling California, individually at a later time.
Basin and Range details the history and internal structure of the landforms that characterize Nevada and Western Utah. In this narrative McPhee travels with a geologist expert in the topic, Kenneth Deffeyes, of Princeton University. The account includes not only instruction and explanation by Deffeyes, but McPhee's own detailed exposition and guidance to useful literature on the topic and region. This is the format applied throughout the omnibus. McPhee quickly exposes the reader to the vocabulary of geology. At times he treats it as a literary opportunity and seemingly plays with the words for their effect alone.
The travel companion in book two, In Suspect Terrain, is Anita Harris, a respected research geologist in the U. S. Geological Survey. A native of Brooklyn, she told McPhee, "I knew that if I went into geology I would never have to live in New York City." Their travel takes them on I-80 from New Jersey to Chicago, examining geological profiles, almost roadcut by roadcut, along the way. McPhee develops the history and content of the geological theory of drifting continents, or tectonic plates. This gained widespread acceptance following research in the 1960s. Harris serves a a bit of a foil to the theory. She accepts, and incorporates parts of the theory, but not all. Her sense is that the proponents are too accepting, not taking time to explain away discrepancies.
The mid-continent shows few rocks. This region was geologically stable, lacking the mountain building of Nevada or the Northeast. Here the basement rocks lie covered with soil. To see Nebraska's underlying rocks, one must go to Colorado. There those rocks have been uplifted and exposed. McPhee finds his specialist tutor on this region in University of Kansas professor Randy Van Schmus at the University geology field camp in Colorado. The rock layers under examination are ancient, from before life on earth to leave behind fossil remains. To differentiate and determine the age of these rocks such markers as their magnetism and chemistry must be found. McPhee and Van Schmus detail the technology that provides such information. It is a mind-boggling process.
Annals is an ultimately informing book. It also instills a sense of wonder about the natural world, especially with regard to the concept of time. One can relate fairly easily to the idea of billions of dollars (though we personally may not deal in those figures), but the idea of billions of years remains unfathomable. And yet, that is the reality, 4.5 billion years, at the heart of this book. The science, the vocabulary, and the shifting locations make this book a challenge. Can you create a map in your head? A suggestion is to try one of the individual earlier titles; the reduced bulk may make the challenge seem more manageable. Taken one at a time, the two books covered here would rank as 4 stars each.
