NB: Unemployment has *not* done wonders for my reading time.
Next up is the latest in the Roadside Geology series, in my adopted State no less.
Richard Ojakangas is a native Minnesotan whose life has been spent in learning about and teaching Minnesota's geological history. He taught at the U of M in Duluth for over 30 years, and is the author of Minnesota's Geology, which is probably the definitive geology book on the North Star State.
That book, however, is not quite meant for the casual reader (although its less imposing than many other books of the type). Minnesota has lacked a Roadside Geology style book for too long. After years without one, Ojakangas has finally written a book for the non-scientist, the latest in the Roadside Geology series, the Roadside Geology of Minnesota.
It's been worth the wait.
After an introduction to the geological history of Minnesota (as you might expect, the Pleistocene, with its glaciations, gets a lot of space) as well as some basic geology to get those who avoided the rock science in high school or college, the book divides into several sections based on Geography. (Northeastern, Northwestern/Central, Southwestern, Southeastern)In each section, Ojakangas gives a general overview of the Geology of that area followed by the meat of the book, Road Guides.
There are plenty of photographs, maps and diagrams to elucidate the text and keep travelers oriented as they visit the various highlighted sites. I learned about plenty of sites that were just off of my route in previous travels that I will definitely visit with book in tow. I had no idea, for instance, of a beautiful beach of rhyolite pebbles lies just 3 miles north of Gooseberry Falls. I'd never heard of Chimney Rock, a spire of sandstone a few miles off of US 61 on the way south from St. Paul. In addition, I have an appreciation for places and locales I have seen, now having a better geological context for them. The composition and nature of Barn Bluff in Red Wing, for instance. I had no idea there's a fault that has shifted the layers on one side of it!
Armchair amateur geologists who buy the Roadside series of volumes will not want to miss this latest volume.I most especially recommend this book, though, for any and all Minnesota travelers interested in the physical geology of the state to buy the book, read it, and then take it with you on your next road trip to, say, Gooseberry Falls, or Winona, or the Boundary Waters, or Pipestone. I certainly will!
