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.”

The real danger lies in our loathing of man and our pity of him.

And indeed, preparations for that event are already well underway.

[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.


It’s Time to Go Back on the Road

As of today I’m three weeks into my new public-outreach initiative and the response has been encouraging, to say the least.

At last count, fourteen public libraries, nature centers, gardening groups, and educational institutions in northern Illinois have scheduled me to present natural-history talks and to lead tours.  More, I’m told, are on the way. (See my Upcoming Events page for all the details.)

But this isn’t just (or even primarily) about one educator scaling back his college teaching so he can return to his old love of writing and direct involvement with the public. It’s a small but potent indicator of what I sense is a much larger trend.

At a time our newly elected federal administration is trying its damnedest to roll back environmental safeguards, to pin the vastly researched and substantiated issue of climate change on a hoax perpetrated by the Chinese, and to turn the workings of governance into freakish self-parody,  public institutions and citizen’s groups are counter-punching, consciously or unconsciously, by showing revivified interest in presenting natural-history themes to their constituencies. Or so it seems on my stretch of turf.

If my supposition is true, we’re witnessing a very human invocation of Newton’s third law: an equal and opposite reaction to the original disturbing forces of nature blindness and unbridled greed. It just might be that species Homo sapiens is at its best when it’s pushing back against patent absurdity. At any rate, may this trend last as long as I’m taking my show on the road — and much, much longer than that.

In his Outline of History, H. G. Wells noted all too prophetically that “human history becomes more and more a race between education and catastrophe.” There’s no doubt about that. But it’s finally time to realize what education actually is — especially nature education.  Online and social-media interactions aren’t enough. Watching shark specials or disaster documentaries on a glaring, vision-degrading screen aren’t enough. The acquisition of worthwhile knowledge intrinsically requires face-to-face human interaction. Listening to someone who has something informative to impart. Then discussing it, and framing new ideas based on what you and other people think.

So hit the road yourself. Put the phone away for a while and get involved in a local fossil-collecting, gardening, or birders’ club. Or take a real, nonvirtual geology or biology course at your local community college — not just so you can get a higher-paying job, but to better read the greater world around you and thereby become a better citizen. Urge your local library or nature center to present talks and activities where you can actually learn something new and not just be entertained (pace puppet shows, Celtic-music groups, and tree-planting ceremonies). And if you’re in northern Illinois or have the ability to get yourself there, consider stopping by for one of my public lectures. It would be a pleasure to meet you.


This site was begun on 6 February 2017 as an update and reworking of Ray Wiggers’s earlier site, which, after the better part of a decade, had to be discontinued due to his heavy college-teaching load.

Now that this site is up and running, pages and updated information will be added frequently — everything from listings of public talks and tours to blog posts on important natural-history topics.
