Callan Bentley A fun, if a little musty, compendium of random writings about geology and geologists from a wide variety of sources, excerpted and packed together into a slim paperback volume. It begins with Mark Twain and concludes with Russell Baker, and there are hundreds of entries in between – some poems, some short essays, some clipped … Read more
This is a thoughtful volume on mass extinctions written for the novice. One thing I really liked about this book is that it was written very clearly from the mind of a skeptical scientist who is conscientious about explaining each step in his thinking while explaining fairly complicated, murky stuff for a lay audience. Hallam … Read more
Callan reviews a recently-published book that offers “a new geological history of North America.”
My favorite popularizer of modern geology is Marcia Bjornerud. Her sensibility for what is interesting and important matches very nicely with my own – I feel she is a kindred spirit, though one infinitely more talented with language than I am. Lovers of geology found much to delight them in Reading the Rocks. She took … Read more
The Great Derangement: Climate Change and the Unthinkable, by Amitav Ghosh Marcia Bjornerud put me onto this one. An interesting book that explores the roots and results of our response to climate change. The author, an acclaimed Indian novelist, is particularly interested in the unwillingness of artists and novelists to grapple with climate change, citing … Read more
This weekend, my family and I traveled to a little agrotainment complex north of Harrisonburg, Virginia, a joint called Back Home On The Farm. It featured a corn maze, hayrides, petting zoo, apple cider donuts, and pumpkin picking. All typical fall frolic; good clean fun. But there were also big blocks of limestone everywhere on … Read more
Callan reviews five books, both fiction and non-. In this batch, we get Neal Stephenson’s latest techno-thriller, about geoengineering and its discontents, Barack Obama’s first memoir, a novel by Charles Dickens, a collection of short stories by Andy Weir (author of The Martian), and Bill Bryson’s sole foray into popular science writing.
Happy Saturday! Here are two erratics (glacially transported boulders) that I saw last week in coastal Maine. This one shows prominent subparallel striations: And this one, in the town of Penobscot, next to the greasy spoon called Bagaduce Lunch, shows aligned feldspars that suggest magmatic flow: Nothing like a good erratic to get the weekend … Read more
This volume is a compilation of reporting that author Nathaniel Rich previously published (sometimes in rather different form) in a variety of periodicals, but mainly the New York Times Magazine. The general theme is humanity’s alteration of the natural world, for good or (usually) for ill. The first piece, on West Virginian lawyer Robert Bilott, … Read more
Earlier this summer, I was lucky enough to visit a soapstone quarrying operation in Schuyler, Virginia, right on the Albemarle/Nelson County line. These soapstone bodies are metamorphosed ultramafic intrusions into the Neoproterozoic sedimentary deposits of the Lynchburg Group. The protolith peridotite sill crystallized at ~580 Ma, meaning the host sediments are older than that (but … Read more
