My Interview in “MKE Lifestyle” Magazine


The July 2024 issue of MKE Lifestyle magazine is out, and it contains a “Fifteen Minutes With Ray Wiggers” interview on the subject of my newly released book, Milwaukee in Stone and Clay, and its subject matter.

The digital version of the issue may be found here. The interview starts on page 18. Also, take a look at the rest of this and other issues posted online. There are a lot of fascinating photo spreads and articles on the Cream City’s cultural and historical aspects, as well as quite a few features on Milwaukee’s natural setting and environmental-education resources.

My thanks go to MKE Lifestyle for taking an interest in MSC and the concept of architectural geology.

That said, as all persons in the world of words and printing know, errors can creep into an article with amazing ease. In this case, the caption of one interview-spread photo incorrectly identifies the red, Jacobsville-Sandstone-clad edifice shown as the Loyalty Building. Actually, it’s the Button Block, as is unequivocally stated in MSC. The caption also states that City Hall is made of both St. Louis Brick and Philadelphia Brick. Only the first of these is present, so far as I know. Please note that I am not responsible for these errors.

In book publishing, the author generally does the captions. But in popular-press periodicals, it’s usually a magazine staffer and not the person interviewed who writes them. And there’s usually no understanding that caption facts should be checked with the interviewee. Such was the case here.

But rest assured that the correct information is given in MSC itself. And a correction supposedly will be issued in the August issue of MKE Lifestyle.

In the meantime, I hope you enjoy the interview, which contains much more information that is, to the best of my knowledge, completely correct. And don’t forget to check out my page specifically dedicated to MSC. In my newly added “Item 4” section of that page, I go into the corrections in a little greater detail, and also discuss what I consider to be the most important section of the interview, which was, to my very great regret, edited out of the magazine section. Take a look!








It’s Spring, And My Website Is Blooming Anew

Wild Geraniums (Geranium maculatum) in full flower by my door, a few days ago.

Just last week, after eight months of writing, writing, and more writing, I finished the manuscript for the third book in my Stone and Clay series. It covers the architectural geology of a huge area of northeastern Illinois—about 1,600 square miles—stretching from Homewood in the southern Chicagoland suburbs through the Lower Des Plaines Valley and western suburbs up to the North Shore, Waukegan, and Illinois Beach State Park. Now it’s off for peer review.

If you, too, are a book author, you’ll probably understand that finishing and submitting one’s latest manuscript can definitely produce a sort of post partem depression. But in this case, I was able avoid a fit of the hypos by turning immediately to a number of other projects that have long begged for my attention. So I haven’t had that miserable, what-do-I-do-next feeling this time around.

One  of these projects is a major upgrade of this website. My main goal is to make it, among other things, a discussion forum and information supplement to my books. So you’ll find new pages for both Chicago in Stone and Clay and Milwaukee in Stone and Clay. Take a look, and keep in mind that I will be updating quite frequently from now on.

In addition, I’m also redoing my Lectures and Tours pages so potential hosts and participants will see what I’m offering that’s thematically linked to the Milwaukee and Chicago books.

So . . . let me know what you think!

Kind regards,

Ray Wiggers




For Your Delectation: A Photo Show and a Radio Interview

Over the past couple of months, I’ve done a number of media events and interviews to celebrate the recent release of my new book, Milwaukee in Stone & Clay: A Guide to the Cream City’s Architectural Geology.

Two of these, including a slide show of some of my best geology and architecture photos, have been recorded and are currently available online:

My photo-slide show of Milwaukee’s geology and architecture, co-hosted by Boswell Books and Historic Milwaukee, Inc. It has now been posted on YouTube. Here’s the link . Note: It will be available only until Friday 17 May 2024.

My audio interview on the “Lake Effect” program of Milwaukee Public Radio has been posted as this podcast.

Give one or both a look or a listen if you’d like to learn more about the fascinating and often unexpected links between architecture and geology!

And, while I’m at it, here’s the publisher’s link for Milwaukee in Stone & Clay.



Celebrating the Cream City’s Urban Geology


While its official publication date is still April 15, 2024, I’m delighted to report that Milwaukee in Stone and Clay: A Guide to the Cream City’s Architectural Geology is now “in the warehouse.” In other words, it’s been printed and delivered to the publisher. And it’s now being sent to customers who’ve pre-ordered it, and to bookstores and other outlets.

Here’s the publisher’s link.

If you’d like to get a 30% discount on the book from the publisher, Cornell University Press, just drop me a line at, and I’ll send you an author’s gift card that gives you a QR code that will enable the discount. Note: I can only do this for a short time, because I don’t want to discourage people from buying the book from the talk hosts cited below!

Also, just today (Tuesday, March 5, 2024) my interview about the book aired on WUWM, Milwaukee Public Radio. Here’s the podcast link.

Finally, I will be doing a virtual talk for Milwaukee’s Boswell Book Company in association with Historic Milwaukee, Inc., on May 10, 2024 at 2:00 pm Central Daylight Time. For more on that free event, and to register via Zoom link, go to my Upcoming Events page.

“Chicago in Stone & Clay” Wins Best Popular Geology Guidebook Award

At a ceremony on November 16, 2023 the Geoscience Information Society (GSIS) presented my most recently published book, Chicago in Stone and Clay (CSC), with its 2023 award for the Best Popular Guidebook.

The GSIS, a member society of the American Geoscience Institute and an associated society of the Geological Society of America, is a nonprofit organization composed of science librarians, geoscientists, and other information professionals. One of its continuing and best-known roles is to recognize outstanding books and research papers in the Earth sciences.

I can’t begin to express how honored and uplifted I feel to be recognized by the GSIS selection committee, especially given how many new geology guides appear each year. When I was informed of my selection, the news didn’t just make my day—it made my year.

There’s no doubt about it. I consider this is one of the big achievements of my writing career. This award, along with the Chicago Reader‘s designation of CSC as one of “The Top Ten Chicago Books of 2022,” has given me all the rocket-fueled inspiration I need to carry the Stone and Clay series forward. The Milwaukee volume is due out early in 2024, and I’m now busy writing the third installment, on the Chicago suburbs.

(The awarding officers’ signatures on the certificate above have been typeset to protect their own identity information.)







Coming Soon: “Milwaukee In Stone and Clay”

Sometimes the extended process of writing a book and getting it published makes me feel as though I’m trapped in Zeno’s Achilles-and-the-Tortoise Paradox. However much progress is made, there always seems to be some distance, however miniscule, remaining between me and the goal of seeing the book hit print.

That said, the second volume in my Stone and Clay series is in fact now making its final approach to the finish line. (Forgive the mixed metaphor: I think I shifted within a single clause from an airplane to a racehorse. At any rate, the proofing and indexing of my flying equine has now been finished.)

As it so happens, I’m one of those authors who does my own indexing, and who actually enjoys the process, mostly. But now all that is done, and my Cream City tome is off to the printers. The expected release date? Late winter or early spring of 2024.

I thoroughly expect my publisher (the NIU imprint of Cornell University Press) to once again offer author-distributed discount cards and codes for purchase of Milwaukee in Stone and Clay. If you’d like to receive a sizeable deduction when you buy it from Cornell (probably 30%), drop me a line at and I’ll make sure you get the card and code as soon as they’re available.

And, finally, I have been honored by NIU/CUP with a third Stone and Clay contract—this time, for a guide to the Chicago suburbs, which are a happy hunting ground for anyone interested in the geology of building stone and fired-clay materials. I hope to have that manuscript in for peer review at just about the same time the Milwaukee book becomes available.

A Signal Honor for Chicago in Stone and Clay

I’m unabashedly proud to announce that my recently published book, Chicago in Stone and Clay: A Guide to the Windy City’s Architectural Geology, has been chosen as one of the Chicago Reader‘s “Ten Best Chicago Books in 2022.” To quote from the review by Adam Morgan:

“The city is not a denial of nature. It’s a vast affirmation of it,’ Wiggers writes in this first-of-its-kind guide to the geology of Chicago’s architecture. In surprisingly breezy chapters organized by neighborhoods and buildings, Wiggers explores the stone, brick, terra-cotta, plaster, metal, and ornamental glass that make Chicago an enormous outdoor museum. It adds a fascinating new layer of history to your brain that will change the way you see the city.”

To be so honored by this preeminent publication is a significant career accomplishment for any Chicago-area author, and I’m truly grateful that The Reader found my work worthy of inclusion on its list.

“Chicago in Stone and Clay” Is on the Way!

I’m delighted to announce the scheduled publication date of my next book, Chicago in Stone and Clay: A Guide to the Windy City’s Architectural Geology. It’s September 15, 2022. For the publisher’s description of the book, click on the “Ray’s Publications” link above. There you’ll also see a special 30%-off discount for those who’d like to pre-order a copy.

This book, a product of three decades of research, teaching, and tour-guiding, has been a joy to write. I’ve been blessed with an outstanding acquisitions editor and production team, and I’m so happy with the result I’ve entered into a contract with NIU/Cornell for a second book, Milwaukee in Stone in Clay, the writing of which is now well underway.

Rekindling an Old Flame




Just two weeks ago I crossed through the magic portal:  I retired, not from other and better activities, but from almost two full decades of college teaching.  But even before I’d delivered my last lecture, run my last lab, and graded my last exam, I’d rediscovered at home an old, old flame—a  collection of thousands of quotations I’ve culled from a lifetime of reading in many different subjects.

Starting in the early 1970s I carefully marked the most interesting ideas in each book I read and then, before consigning it to the shelf, wrote down  the passages I especially liked on note cards and looseleaf sheets kept in bulging three-ring notebooks.  Later, a few years ago, I started to transcribe those quotations into digital form. But then the demands of my teaching drew me away again.

Now I’m back at it, hammer and tongs. And—joy of joys for a compulsive organizer—I’m doing it more systematically. First, I’m recording in more permanent form my lists of all the books I’ve read since I began keeping track at the age of twenty-one. They total about 2,700 titles. (To the average modern American this may seem a large number, but when one considers the bibliophiles and intellectuals of the past, it’s really not much to crow about.)  Next, I’m entering the individual quotations on my daily tick list into one of seventy-one different sections that highlight those themes in science, art, religion, philosophy, I deem especially important.

But why should I bother? From traditional print sources like Bartlett’s to a plethora of websites of varying levels of competence and seriousness, aren’t there enough quotation factories already? Perhaps. All I can say is that I’m madly in love and this is something I simply have to do. And so I shall whether or not it ultimately assumes any public form. The real point here is that I suddenly find myself swimming with a tsunami of great ideas, rather than bobbing in the windless sea of third-rate academic cant. It’s an exhilarating ride, and as a small New Year’s gift to you, I share below a few of the items from my ever-growing hoard. Because this site is primarily devoted to natural history, these selections mostly but not exclusively touch upon familiar themes. 

(And by the way, let me know  if you can identify the scribbler pictured at top, who is one of my personal Heroes of Art. At this point I can’t offer the first responder a new sports car or wall-sized flatscreen TV, but you will earn my undying admiration. )

The mists of the North have bewitched the Black, or Pontic, Sea. Beyond it lay the Bosporan kingdom and at its western end the Symplegades opened to the Amazon coast—merciless cliffs with dark patches streaked like walnut leaves in autumn; and the eastern or Caucasian end was known as the ‘furthermost run for ships,” where seventy tribes all spoke their separate tongues. “Thence people go to Amisus and Sinope, a sea voyage of two or three days, since the shores are soft because of the outsets of the rivers,” which build small sombre beaches, blackish like a dream. The water is shallow with flat rocks, and so little salt that rock-doves come to sip it; the foam is not crisp like the Aegean but greenish as old ivory, and loosely spangled; and the sun flecks it weakly, like flashes from rings.

I was as interested in the discovery of limestone as if it had been gold, and wondered that I had never thought of it before. Now all things seemed to radiate round limestone, and I saw how farmers lived near to, or far from, a locality of limestone. . . . I read a new page in the history of these parts in the old limestone quarries and kilns where the old settlers found the materials of their houses.

[Of the eruption of Mount Vesuvius in 79 CE] We had scarcely sat down when night came upon us, not such as we have when there is no moon, but that of a room when it is shut up, and all the lights put out. You might hear the shrieks of women, the screams of children, and the shouts of men; some calling for their children, other for their parents, others for their husbands, and seeking to recognize each other by the voices that replied; one lamenting his own fate, another that of his family; some wishing to die, from the very fear of dying; some lifting their hands to the gods; but the greater part convinced that there were now no gods at all, and that the final endless night of which we have heard had come upon the world.

You would never believe the sport and entertainment that your human puppets provide daily for the gods. You are aware that these gods set aside their sober morning hours for composing quarrels and listening to prayers. But after that, when their minds are well clouded from the nectar and they have no desire to transact business . . . they sit there, gazing down at mortal men and watching them argue. There is no show like it. Good God, what a theater!

“My dear, dear aunt,” she rapturously cried, “What delight! What felicity! You give me fresh life and vigor. Adieu to disappointment and spleen. What are men to rocks and mountains? Oh, what hours of transport we shall spend! And when we do return, it shall not be like all other travelers, without being able to give one accurate idea of anything. We will know where we have gone—we will recollect what we have seen. Lakes, mountains and rivers will not be jumbled together in our imaginations; nor when we attempt to describe any particular scene, will we begin quarreling about its relative situation. Let our first effusions be less insupportable than those of the generality of travelers.”

[Of his exploration of the Andes] When we reached the crest and looked backwards, a glorious view was presented. The atmosphere resplendently clear; the sky an intense blue; the profound valleys; the wild broken forms; the heap of ruins, piled up during the lapse of ages; the bright-coloured rocks, with quiet mountains of snow; all these together produced a scene no one could have imagined. Neither plant nor bird, excepting a few condors wheeling around the higher pinnacles, distracted my attention from the inanimate mass. I felt glad that I was alone: it was like watching a thunderstorm, or hearing in full orchestra a chorus of the Messiah.

Nemo Contra Naturam

After spending many hours driving through the suburban and industrial expanses of my native Lake County, Illinois — many of which are looking decidedly shabbier, more threadbare, and more deserted than they were two decades ago — I unwind whenever possible by hiking in the magnificent nature preserve of Illinois Beach State Park.

Just this morning, on the bank of its Kellogg Creek canal, I had frank and meaningful discussions with a pair of kingbirds in a surviving American elm, with a typically indignant and chattery kingfisher, and a catbird mewing somewhere nearby in  the grapevine-clad shrubs.  Then in the marsh and wet prairie I exulted in the late-summer splendor of the DYCs — the goldenrods and seven-foot native sunflowers that struggling botany students call the Damned Yellow Composites on account of their shameless  hybridization and blurring of identification traits.  Ah, those bold and golden yellows, punctuated here and there by the regal blues and purples of the New England asters and blazingstars. Ah, nature.

On the drive home afterward I passed rows of half-abandoned strip malls and an ex-Kmart whose deserted parking lot is now a tarmac for hundreds of herring gulls. Suddenly a decades-old realization popped back into my consciousness: what I was seeing there, in all the despirited jumble of our decaying consumer culture, was every bit as much a production of nature and its forces as the harmonious and colorful prairie ecosystem I’d just left.

Nemo contra Deum nisi Deus ipse is a Latin maxim used by the great German poet Goethe in his autobiography: There can be no one against God, unless it is God Himself.  I mutate that very pregnant thought into Nemo contra Naturam nisi Natura ipse: There can be no one against Nature unless it is Nature itself.  Everything this planet and its cosmos have suffered to be born is a part of nature, and every human work is, ultimately, natural. And for that reason all history is natural history. When a prominent environmentalist writes a book entitled The End of Nature, he lacks the cold and steely eye of the geologist who knows that humankind is just the latest great disturbing force, very much within nature, driving yet another mass extinction. This is certainly not to say that the environmentalist is wrong to scream bloody murder at the rapid global warming we’re so stupidly causing. But the better title, harrowing enough, would have been The End of Civilization and Various Other Ecosystems. The Earth abideth forever. Well, almost forever, until that part of nature we call the  Sun becomes a red giant billions of years hence.

If we dare to recognize that civilization is as much an efflorescence of nature as a prairie is, it doesn’t mean we have to spend as much time birdwatching at the local Auto Zone outlet as we do in much more aesthetically pleasing spots. There is, as Thoreau and a host of others have noted, tremendous spiritual recharging to be had when one devotes oneself to nonhuman nature in wild places. But neither should we be unaware or disdainful of some magnificent windows that nature has opened for us in urban and suburban settings. In botany, one of the most fascinating things one can do is to study the ecology of weed species on waste ground — with its fascinating examples of survival in harsh surroundings and amazing evolutionary adaptations. From the standpoint of the native-habitat restorationist these often-alien plants may be politically incorrect in the extreme. But even they can teach the willing mind many wonders.

Still, the educator in me has the most fun showing tour participants how much nonhuman Earth history — sometimes stretching back three and a half billion years — there is to be found and celebrated in any built environment — from the collar-county suburbs and Fox Valley towns to the heart of the Loop.  This investigation into the ancient natural origins of our brick, terra cotta, and building stone is the domain of my most fervent intellectual love these days, architectural geology. I’ve just finished a scholarly article on it (publication date as yet unknown). This theme will also be, I hope, the subject of my next book. To get a sense of the proposed book’s subject matter, keep an eye on the photo gallery I’ll be putting up on this site soon and adding to frequently.
