“Stone By Stone” Becomes Audiobook

September 2002 saw the publication of Stone By Stone: The Magnificent History in New England’s Stone Walls.  Within a week it became a steady New England bestseller. Within the year it went through several hardcover printings and earned the 2003 Connecticut Book Award for nonfiction. By 2004, it was released in paperback.  Originally published by Walker & Company, a new edition was published by Bloomsbury.  The book continues to sell off the backlist.

Throughout it all, there was no audiobook.  This changed in summer 2022 when Tantor Audio, a subsidiary of Recorded Books since 2015, saw an opportunity to publish  this “classic” as an audiobook, doing so on October 25, 2022.  I had the opportunity to read the script.

For those of you who are interested, ask your library to order the audiobook or simply purchase it from Tantor Audio.

Stone Shelters in the Sierras and New England

Shelter in Sierras
Stone Shelter in White Mountains, CA, USA in the glacial high Sierras. Elizabeth Wing.

Years ago, I was traveling through the small town of Putre in northern Chile, when I saw something astonishing.  The shape, size, and composition of its ancient stone walls in the high Andes at an elevation of 3500 meters (11,060 feet) were remarkably similar to those I’d seen in the lowland hills of interior New England. Though the inhabitants of pre-Columbian South America were raising camelids rather than sheep and cows, and though they were worlds apart from post-Columbian North American Yankees, their primitive farmstead stonework was remarkably similar.  Why?  Because the same three fundamental factors came together in time and space: the need to enclose grazing animals in heavily glaciated terrain underlain by crystalline igneous and(or) high-grade metamorphic rock.

Similarly, The Distinctively Basque Stone Shelters of California’s White Mountains, are remarkably similar to some I’ve seen in New England because the same three factors were controlling the outcome: animal enclosure, glaciated terrain, and hard crystalline rock.  This new, 2022, article by Michael R. Wing, Elizabeth H. Wing, and Amin M. Al-Jamal, describes the shelters built during the mid 19th century to protect sheep grazing in the high meadows of the White Mountains of high eastern Sierras of California. The phrase “distinctly Basque” refers not to a cultural style of construction, but to the certain historic knowledge that they were built by Basque (or adjacent French) herders.

The captioned illustration above reproduces their Figure 1, a photo of Big Stone Shelter, which located above tree line at an elevation of 3840 meters (12,600 feet), even higher than in Putre, Chile.  Its features –a glacially rounded boulder, a mix of angular and milled stones, the overall form, and the pattern of stacking– are identical to those of primitive fieldstone walls in New England.  And though this shelter is a small enclosure rather than a wall around a land parcel, New England has many such small enclosures in its formerly de-forested highlands, or as niches attached to walls.  Whether some or all of these were roofed with organic material that has since decomposed is unknown.

The similarities in expedient stone construction built by indigenous inhabitants in the high Andes, Basque herders in California Sierras, and farmers in New England demonstrate the adage that form follows function, regardless of historic or cultural setting. Such walls are ecofacts as much as they are artifacts.

Of course, the story of stone structures everywhere is much more complex than the simple connections made above. And these three connections are only a few among many.  But the conclusion is always the same. Beneath cultural overlays, the expedient architectural requirements of herding animals in rocky glaciated landscapes produces similar results.


Landscapes within Walls within Frames

Last spring I had the pleasure of meeting Gary Perdue, a retired producer/director for Public Television who took up photography as a serious hobby, and the stone walls of Rhode Island as his subject.

After years of shooting, he designed an exhibit in which he arranged his photographs as if they were stones in a wall, and then framed that arrangement as if in the profile view of stone wall.  The frame shown in the image above is one of a dozen or more that, taken collectively, create a powerful exhibit.  I had a chance to see it when he drove it to Storrs, CT from State College, PA in a U-Haul van, accompanied by his wife and son.

Gary is seeking additional venues for the exhibit.  If interested, please contact the SWI coordinator Robert M. Thorson  via the Stone Wall Initiative.


“Living on Earth” features Stone Walls

“Many of New England’s stone walls, like this one in New Hampshire, are going back to nature as they fall into disrepair and become overgrown with moss. (Photo: mwms1916, Flickr CC BY-NC-ND 2.0)” [Photo and caption from Living on Earth.]

Living on Earth, hosted by Steve Curwood, is Public Radio International’s weekly Environmental News Magazine. On November 30, 2018, it aired three long segments: Trump Climate Change Report, featuring John Holdren, Obama’s former science advisor; Saving the Sumatran Rhino, featuring freelance journalist Jeremy Hance, and New England’s Stone Walls, featuring Steve Curwood and I examining an abandoned 1755 farmstead in New Hampshire.  The highlight of that 10-minute podcast is the recorded voice of Robert Frost reading his poem Mending Wall.

Other topics include answers to the questions:  Who built the walls? Why are they special habitats?  Are humans part of their geology? Did wall  help win the American Revolution?

Stone Therapy

Above is a “pile” of well-stacked stone on a boulder somewhere in western New England. This activity would have helped clear a field or pasture. But more importantly, it turned the mundane act of clearing land into a stacking game, leaving cairns and stacks for us to puzzle over and misinterpret as sacred sites.


Yesterday, I learned of a curious case of stonework performed by an elderly man with dementia. The anecdote, published in the Providence Journal for September 2, 1895, refers to a time “60 years ago,” which dates the case to the mid 1830s.  In this case, the stonework was done as “keep-busy” therapy for an aging farmer with dementia, a reason not usually cited as an explanation for odd stone structures found throughout New England.

It is one of the few cases in my experience where the origin of stone structures –walls, piles, enclosures, cairns– is specifically documented in time, place, and purpose.   The lesson here is that odd stone structures need not be expedient or symbolically sacred.  Unless proven otherwise, those dating to before and after European contact might reflect little more than individualistic, idiosyncratic responses to behavioral cues.

Specifically, an “uncle of the owners” living on “the Josiah Dyke place” in northeastern Connecticut, likely East Thompson, had dementia (also known as senility), the condition of losing one’s mind –especially one’s memories– as part of the aging process.  This particular uncle “spent his whole time in the fields, which are full of stones of all sizes, picking up the stones and placing them with great care in heaps” that were “piled up without mortar into pyramids” that “tapered slightly and reached a height of six feet or more.” They were “so well and so solidly built that although built 60 years ago they are still in as good condition as ever, except where mischievous boys have torn them down.”  “The work was so well done that it became a wonder of the countryside,” bringing gawking visitors in “from far and near.”  

The stones remain as a testament to dementia, a condition that plagues millions of adults today, and to the value of stonework in happily passing the time as a form of engagement with the world, even when one’s mind is slip sliding away.   I know this condition from direct experience because my own 96-year old father has it today.  Being a former band conductor, he physically directs the musical memories floating through his mind.  Another resident of his managed care facility knits while she walks, again a response to the urge to do something physical.   Had my father been the farmer’s uncle from 19th century New England, however, he might have felt the urge to stack stone to occupy his mind to pass the time away.

My favorite aspect of this story is that the micro-history of this demented builder faded away in only six decades. Cultural memory and individual memory both fade away, leaving archaeology to fill in the gaps.

NOTE:  This anecdote is based on an excerpt sent to me by Dr. Tim Ives, the Rhode Island state archaeologist. The original is below the line.  Note that the location is given as “northwestern” Connecticut when it is almost certainly “northeastern,” an easy mistake to make by the author.

“This is not the only curiosity of this region, for the whole country in northwestern Connecticut is full of eccentricities of nature and man. On the Josiah Dyke place, in this region, are a number of curious heaps of stones, piled up without mortar into pyramids wThey were placed there over half a century ago by an uncle of the owners of the property. He was demented and spent his whole time in the fields, which are full of stones of all sizes, picking up the stones and placing them with great care in heaps which tapered slightly and reached a height of six feet or more. The work was so well done that it became a wonder of the countryside, and people came from far and near to look at the stone heaps. Now they remain in the fields, visible from the road, although their builder has long since passed away, and few of the farmers in the locality know their history.”

“Getting” the Anthropocene

The Anthropocene is the epoch of geological time we are currently living in, a discrete interval of Earth history during which the collective actions of a  single species —Homo sapiens— is the dominant geological agency operating on our planet. Though the “epoch” is not yet an official “Epoch” (owing to international debate over the date of its lower boundary), there’s no doubt that we’re in the thick of it.   The preceding epoch, the Holocene, contained the bulk of the present interglacial epoch when the human agency was less impactful.  For New England stone walls, the Anthropocene onset dates to 1607, when the first wall was built by the first English colony at Popham Point, Maine.

Work at the University of Connecticut, especially a 2016  article published in the Elsevier journal Anthropocene by Katharine M. Johnson and Will Ouimet, is bringing New England walls to an international audience (Physical properties and spatial controls of stone walls in the northeastern USA: Implications for Anthropocene studies of 17th to early 20th century agriculture,

Philosophically, the key idea for me is that, in the woods of New England, the main Anthropocene impact is already past and was generally positive in diversifying the landscape and leaving archaeological ruins that enhance our lives.

“Gray rectangles on the gray hillsides.” An ode to Donald Hall

“The Veteran and a New Field,” by Winslow Homer (1865), selected from the Metropolitan Museum of Art as the cover Illustration for Donald Hall’s memoir “Life Work” (Beacon Press, 2003). 

Why this mention of Donald Hall on the SWI website?  Because –more than anyone else except Robert Frost — he helped me understand what the rural New England psyche was all about, and why it’s so tightly tied to fieldstone walls.  He did so for me neither in person nor poetry, but in his literary nonfiction.  I treasure my signed copies of his books, and my memory of when he signed them.  I write this post on the occasion of his very  recent death on June 23, 2018 at the age of 89, the end of a flesh-and-blood life summarized by his obituary in the New York Times.

Why this image of a flat, stone-free, warm, highly productive field?  Because it’s everything that Hall’s outdoor prose was not,  offering a well-deserved rest from the hilly, hardscrabble, colder, and tougher landscape of his actual life, as exemplified by this passage from  Seasons at Eagle Pond, a collection of essays written from his family farmhouse on New Hampshire’s  Grafton Turnpike, and published in 1987 by Houghton Mifflin.

And although we may regret the darkening day, the beauty of late autumn is real and serious. With the leaves down, granite emerges from the hills, and everywhere we see again the hill’s true shape and the stonewalls that the ancestors built—to enclose their animals and to clear their fields of rocks—making gray rectangles on the gray hillsides.

My introduction to Donald Hall was through another small book of collected essays —Here at Eagle Pond–wand published in 1990 by Houghton Mifflin.  It’s penultimate essay, titled “My New England,” helped bond me to New England, having arrived six years earlier as an alienated immigrant from Alaska who arrived married a woman from Maine.  His essay gave me the cultural identity I was seeking beneath the plasticized exit-ramp culture of our lives.   On page 189 he wrote:

Even today, the culture of the North Country derives from people who moved inland from coastal cities to wilderness late in the eighteenth century. The veterans and families who headed for the lonely north selected themselves to work harder than their brothers and sisters, with less comfort, in return or independence.  Six Keniston brothers fought in the Revolution, one of them my great-grandfather Ben’s grandfather.  They grew up outside Boston and after the war scattered north along with thousands of their fellow veterans to the woodlands of new Hampshire and Maine and what would become Vermont.

Paul Fenton’s ox-cart man brought the dream of liberty north after the Revolution. This independence was not so much the abstraction of the Declaration – lofty, glorious, and Frenchified – as it was a dream  whereby the single unit of a family could exist in benign anarchy without regulation or cooperation.  The liberty boys wanted each man his own nation, little city-states in the hills, small valleys dividing narrow units separated from each other by granite.

Separateness from others was not a price to pay but a reward to win. Settlers built rudimentary houses while they cleared ancient trees and moved rocks, making stonewalls.  Because each family settlement required about forty acres for survival, they could not be crowded. They would never acquire one or save it, but they would contrive their own comfort.  The natural world provided wood for warmth and ice for chilling; add a great garden, with a root cellar for storing apples, potatoes, squash, cabbage, carrots, turnips; add one cow; add deer and turkey shot in the wild, sheep for shearing, maybe flax grown to make linen, bees and sugarbush for sweetness.  In this society, men worked in woods and fields while women labored inside at ten thousand tasks.  Notions of self-sufficiency became a brief reality—which still creates New England character, in the endurance of its superannuated dream.

This works for me. Someone who understands the ionic-strength cultural bond between New England’s stone walls and its regional identity.  Or, as I once wrote: “The soul of New England perches on a rock.”

“Atlas Obscura” on New England’s Stone Walls

“Stone wall, with moss, Putney, Vermont,” by Anna Kusmer.

Earlier this spring, Anna Kusmer, working on an AAAS (American Association for the Advance of Science) science writing fellowship, interviewed me for a story about New England’s fieldstone walls for the internationally popular website Atlas Obscura.  Their “mission is to inspire wonder and curiosity about the incredible world we all share.”  Her piece, titled New England is Crisscrossed with Thousands of Miles of Stone Wallsnicely summarizes the continuing fascination we have for these old walls, and the work of the Stone Wall Initiative in helping to appreciate and conserve them.   To help share her work, I reproduce her lead image.

Highlights from “Northern Woodlands” Magazine

Drawing by Adelaide Tyrol for Northern Woodlands Magazine, March 18, 2018.






On two recent occasions, I was interviewed by Joe Rankin for two articles on stone walls for Northeast Woodlands magazine.  The first was about the creatures inhabiting stone walls.   The second was a Q&A on curious facts about stone walls. Below are a few key illustrations with detailed captions. I found both articles very interesting and nicely done.  The links are embedded in the descriptions above.

Below are two photos with captions that I sent (and they edited) for the second article. I share them here because they show a  remarkable contrast between two of New England’s “wild walls” (not mason-built or maintained), and help illustrate how the precise technical (but not esoteric) language of my classification (Exploring Stone Walls, Walker, 2005) can help us understand the phenomenon more richly.

“Robert Thorson’s teaching wall in Storrs, Connecticut. This is the archetype wall for the crystalline metamorphic terrain of southern New England: a classic farmstead wall consisting of a single, un-coursed tier of stacked two-handers.” 
“This remnant of single wall construction in Lyme, New Hampshire, shows a variety of features: Shapes are blocks, slabs, and pillows; sizes are mainly two-handers, with one one-hander; order is stacked, rather than laid or tossed; structure is a single-tiered, un-coursed wall one-on-two-and-two-on-one, with one error; lithology is mainly granite and gneiss.”

A Few Interesting Facts

On two recent occasions, I was interviewed by Joe Rankin for two articles on stone walls for Northeast Woodlands magazine.  The first was about the creatures inhabiting stone walls.   The second was a Q&A on curious facts about stone walls.  In preparation for the second interview, I jotted down a few points for discussion, which I share below:

Stone walls are landforms.  In fact, they are signature landforms, defining our region as do the lakes of Minnesota, the caverns of central Appalachia, the canyons of the Southwest, and the volcanoes of the Northwest.  Indeed, we live in the Anthropocene epoch, in which human beings are the dominant agency on the planet.  One of the things we do is move mass from one place to another at a greater average rate than did the glaciers during the ice age, a previous epoch.  The stone walls are the most widespread an ubiquitous indicator of our power.

Stone walls reveal that we are part of nature.  Prior to the age of fossil fuels, the mass moved by muscle power is so monumental, the geographic pattern so widespread, and the style so uniform that we must concede that New England’s stone walls emerged naturally as a consequence of the conversion of forest to farm.  Above this “natural” expression of agroecology is the cultural gloss.  Thus, walls are more analogous to the dam’s of beavers than to the fortress walls of castles.  They are “artifacts” arising from an ecological imperative.

At the peak, there were about 250,000 miles of stone wall in New England, based on historic inventories by Robert Thorson (Stone by Stone) and on statistical predictions based on LiDAR mapping in southern New England by a team from the University of Connecticut [1].

The average height of a stone wall is indeed “thigh high,” as Thorson claimed based on the anecdotal evidence of thousands of walls.  This average wall was confirmed by Johnson and Ouimet’s statistical analysis to be 0.76 ± 0.23 m high and 0.96 ± 0.50 m wide.

Prior to the Gilded Age (of outside money), most walls were built on farms one segment at a time by people from those farms and with resources coming from those farms.  During and after the Gilded Age, many of the original walls were built (upgraded) as capital improvements by expert laborers (masons) paid for with money coming from urban and industrial wealth.

The oldest documented stone wall in New England was built in 1607 by English residents of a “Virginia” colony at Sagadahoc, Maine, now known as Popham Point, located at the mouth of the Kennebec River, Maine.  A letter describing that site from the 1620s described “Rootes and Garden Hearbes and some old Walls” left behind after that one-year attempt at colonization failed [2].
