The author is (properly) defensive about his state's lack of scenic wonders. For a fact, any random square mile of Utah probably will have more visible, interesting geology than the entire state of Illinois. That being said, Mr. Wiggers manages to make what geology there is fairly intersting. I think this book would be ideal for someone who lives in Illinois. He provides thirty-seven sites spread thoughout the state that could be visited on a day or weekend trip and teach you a lot about your state you probably didn't know.

Geology Underfoot in Illinois nicely points out that this state is not all corn and fields! The book is divided into chapters by county, so quick reference is easy. Directions to the interesting geologic formations are given, but sometimes these directions can be ambiguous and confusing. The explanations of how formations occurred are concise, interesting, and easy to understand. This book is perfect for geology students, travellers, and people living in Illinois. It's best when used as a field book; as a casual read it tends to be repetitive and dry.

... and he shows his affection in every word of _Geology Underfoot in Illinois_. Here the reader will learn, in a casual and sometimes humorous way, the history of the Prairie State, what rocks and minerals it holds, and prevailing overall, how the glaciers impacted North American terrain during the Ice Age. Because the book proceeds regionally from north to south, natives and tourists alike can follow along by car or on foot. But even if you never visit Illinois, there are juicy tidbits for you to chew on and be surprised by. Like the fact that Illinois is NOT flat. Like the bizarre origins of the Streeterville neighborhood, which was created in the 1880s only after George "Cap" Streeter grounded a ship along the Lake Michigan shoreline and encouraged construction waste to be dumped around it to form a landfill. Or what happened to the Amoco Building when its pricey Italian-quarried marble sides were exposed to the extremes of Chicago weather. Or the fact that the kitty litter capital of the world may very well be located in the southern tip of the state. Sadly, the black and white photos chosen to accompany the text miss the mark in capturing the true beauty of the sites. You'll simply have to see the places in person.

The author continues to make numerous appearances at nature centers and society meetings throughout Illinois. His presentation style in likable, informative, and funny, and audience members walk away knowing more about geology than they would have guessed possible. If you get a chance to see him speak, take it. You'll find the time well spent. [This reviewer was an Illinois resident when these comments were written.]
