This Sunday, Jan. 3, 2pm: Grounds Tour and Pawpaw Patch Planting Party


To usher in the new year, our Friends of Herrontown Woods group is hosting a gathering this coming Sunday, Jan. 3, to show off the recent transformation of the Veblen House landscape. Should be a beautiful day, but cool, so dress warmly, and we'll have something warm to drink. In addition to touring the grounds, you can participate in a planting of pawpaws to symbolize new beginnings, not to mention future harvests of delicious tropical-tasting fruits.

Directions: Reach the Veblen House by entering the gravel driveway across from 443 Herrontown Road in Princeton (look for Rotary sign wrapped around a tree), or by taking the trail from the Herrontown Woods parking lot up to the farm cottage (cedar shingle siding) and taking a right through the fence. Veblen House appears as a small white square on this map, north of the parking lot.

Just a few months ago, the grounds around the house were choked with invasive shrubs and wisteria vines. That was before the Tazelaars brought loppers and saws to bear, clearing large areas and opening up pleasing vistas of what I call "the many circled land". Veblen House is located at the edge of the Princeton Ridge. To the east is farmland; up the hill to the west is boulder heaven--boulders born not of glaciers but of ancient upwellings of molten rock. Straight rock walls extend through the woods, marking the edge of what once were 19th century pastures. But at Veblen House, the boulders were put to both functional and aesthetic use. The photo above shows the horse run, where horses could be exercised.


In this photo, a portion of the oval of stones circling the Veblen House can be seen, and an old fencepost in the foreground, likely made out of decay-resistant black locust, is one of several that delineate what was a second and larger oval around the house.


The stone fish pond in the foreground makes a half circle that faces the oval of stones around the house.

There's another, smaller circle of stones that forms a funerary some distance from the house, where the ashes of the Veblens may well have been placed.

And the wells, of course, are all circles dotting the landscape. In the photo is one of three relatively shallow wells that form a line extending from the house, as if they were cleanout points for a long pipe meant to carry wastewater far from the house. One of the wells we discovered just last week, it having been completely hidden under the growth of invasives. Four other wells on the property were for drinking water, bringing the total to seven.

This newly opened area, which receives runoff and seepage from the higher ground up near the house, appears perfect for a paw paw patch. Just one week ago, it was dominated by monster specimens of thorny multiflora rose that, with some major energy input from Kurt and one of his brothers, have been relocated to a brush pile.


The pawpaws were donated by a friend, Stan, who has a knack for growing pawpaws, persimmons, sunchokes, and all sorts of interesting native species that hover on the periphery of our diets, just as Oswald and Elizabeth Veblen's remarkable legacy hovers on the edge of people's awareness.

Fall Flowers Bring December Showers


If Thorstein Veblen, Oswald's famed economist uncle, could coin the term "conspicuous consumption", then why not give it a go at the Veblen House? "Fall flowers bring December showers". There. It may lack the trochaic meter of "April showers bring May flowers", but it wasn't much "toil and trouble" to come up with. And clearly it's true. I mean, this flower was blooming in front of the Veblen House on November 28th, and we had rain the first week of December. Clear correlation.

Or maybe it's that, as winter forgets how to be winter, trees lose their bearings. El Nino, like the wizard Prospero shipwrecked on an island far off in the Pacific, has been playing tricks. There was a memorable conversation between two young men on the train headed into NY a few months ago, in which one described to the other El Nino's impact on our weather in New Jersey. "I don't know if I buy that," said the other, not ready to embrace the concept that the world is so intimately interconnected. Sometimes it's these not so clear correlations that turn out to be true.

Topologist Ian Agol, Veblen Prize recipient, wins Breakthrough Prize

A winner of the 2013 Oswald Veblen Prize in Geometry, Ian Agol, has also just won a Breakthrough Prize of $3 million, for what the prize foundation terms "spectacular contributions to low-dimensional topology and geometric group theory". In a NY Times article, Mark Zuckerberg, one of the founders of the Breakthrough Prizes, described them this way: “The Breakthrough Prize honors achievements in science and math so we can encourage more pioneering research and celebrate scientists as the heroes they truly are.”

Though Agol is based at the University of California, Berkeley, he has a one year position at the Institute for Advanced Study, which includes leading a workshop on 3-dimensional manifolds the week of Dec. 7.

It's interesting to trace the lineage of mathematicians via the Mathematics Genealogy Project. Working back from Ian Agol, for instance, the string of advisors are Michael Hartley Freedman, William Browder, John Coleman Moore, George William Whitehead, Jr., Norman Earl Steenrod, and then Solomon Lefschetz, who succeeded Oswald Veblen as Fine Professor in Princeton's Department of Mathematics after Veblen moved to the IAS in 1933. Another bio of Lefschetz, who was trained in Europe, can be found here.

Agol's thoughts upon receiving the Veblen Prize can be found on pp. 14-16 at this link.

Celebrating the Lives of John and Alicia Nash


There was an extraordinary day of celebrating the life and work of mathematician John Nash and his wife Alicia at Princeton University on Saturday, October 24.

Coming five months after he and his wife were killed in a car accident while returning to Princeton from Newark Airport, the series of talks about his work culminated in a moving talk by Silvia Nasar, author of A Beautiful Mind. It's a powerful story of Nash's descent into schizophrenia. That he had Alicia to return to was mentioned as a powerful force in what for victims of the disease was a rare recovery, allowing them to share many good years before they were taken from us.




The talks were followed by a remembrance service at Princeton University Chapel. There's a writeup with photos on the Princeton University website. Though I didn't know John Nash, I found the service very moving--the beauty of the music, the testimonials, the splendor of the chapel. Jim Manganaro, who was a good friend of the Nashes and has expressed ongoing interest and support for the Veblen House project over the years, was one of the speakers. Noting John Nash's precise use of the english language, he told the story of Alicia saying at the dinner table that an offering of pie was too big for her, since she was on a diet. John pointed out that the piece of pie was not too big for Alicia, but too big for a diet.


A Veblen connection--a chapter of A Beautiful Mind begins with a description of "May" Veblen, Oswald's wife--is written about in a previous post.

Update, Nov. 10: I heard from Joseph Kohn, who MC'd Silvia Nasar's presentation, that the various talks will be making it on to the internet at some point.

Clearing (Around the) House


Friends of Herrontown Woods board members Kurt and Sally Tazelaar have been doing lately what few of us imagined possible. The stone features that once graced the grounds around the Veblen House, long obscured by thick, intimidating stands of invasive winged euonymus, privet, honeysuckle, wisteria, and multiflora rose, are now becoming visible again. Boulders in the garden near the house, the large round "horse run", the 75' by 30' footprint where a barn once stood, a rock wall left over from a farming era--all can be seen again as the pleasing vistas of this wooded site are opened up.

One can begin to see what drew the Veblens to this location, and the pleasure Einstein and others took in visiting.

I recently attended a committee meeting in Princeton where people expressed pessimism about ever winning the battle against invasive species that crowd our nature preserves with inedible foliage. Because wildlife depend on native plant species for food, the dominance of non-native invasives effectively shrinks the functional acreage of habitat Princeton worked so hard to preserve.

Kurt's and Sally's work supports a more optimistic view. Kurt views the Herrontown Woods preserve not as passive open space, but as a gym where he gets his very active daily workout, wielding a saw and a pair of loppers to cut down invasives. With this sort of thinking, he sees habitat restoration not as an occasional workday, but as a way of life that keeps him fit and rewarded with a deepening sense of accomplishment. The invasive plants grow 24/7, so an effort to counter them must emulate that persistence.

It is this sort of example, that feeds optimism and empowerment in an era where problems seem to grow beyond our capacities to respond, that is the most rewarding aspect of our work to restore the Veblen House and grounds.

Herrontown's Farming Tradition Continues


Adjacent to the Veblen House property in Herrontown Woods, a daily ritual is taking place. John Powell is giving this year's two head of cattle (easier just to call them cows) a feeding of grain. Former manager of Jac Weller's farm (now Smoyer Park), John continues the tradition of farming in a part of Princeton that once was home to many small subsistence farms, as the rock walls that thread through Herrontown Woods attest.

While the cattle are distracted with food, John goes after several pesky horseflies on the cattle's backs.

Neighbors and passersby love the sight of the cattle in the pasture. In addition to working with the county to acquire and preserve the Veblen cottage nearby, which is an 1870s farm cottage, the Friends of Herrontown Woods hope to see John's farm preserved, and have offered to help with management of this mini-farm in coming years, so that one small part of the Herrontown neighborhood's farming tradition can continue far into the future.

Weyl Fermion Discovery--The Veblen Connection

When I saw the headline "After 85-year search, massless particle with promise for next-generation electronics discovered" among the Princeton University website's top stories, my response was a bit cynical. So many headlines tease us with important discoveries that could transform society, only to reveal deeper into the text that the discovery won't find practical uses for decades, if ever.

The text reporting this discovery, however, got more interesting as it went along. Turns out the massless particle was first proposed "by the mathematician and physicist Hermann Weyl in 1929." If you look at the Robert Nolan biography of Oswald Veblen, you find that Veblen "was largely responsible for selecting the other members of the original faculty (of the Institute for Advanced Study): James W. Alexander II, Albert Einstein, John von Neumann, and Hermann Weyl."

The Princeton University article goes on to say:
"Weyl fermions have been long sought by scientists because they have been regarded as possible building blocks of other subatomic particles, and are even more basic than the ubiquitous, negative-charge carrying electron (when electrons are moving inside a crystal). Their basic nature means that Weyl fermions could provide a much more stable and efficient transport of particles than electrons, which are the principle particle behind modern electronics. Unlike electrons, Weyl fermions are massless and possess a high degree of mobility; the particle's spin is both in the same direction as its motion — which is known as being right-handed — and in the opposite direction in which it moves, or left-handed."
Maybe someone's imagination, massless and possessing a high degree of mobility, will find useful applications for the Wehl fermion much sooner than later, in which case we will need to invent a dance in which we all spin both directions at the same time.

Veblen's Mathematical Genealogy


I was talking to a classical pianist the other day, and told her I'm three generations removed from Bela Bartok. She replied that she's 6th generation Beethoven. My link to Bela Bartok stems from having studied piano with Michele Cooker, who studied with Gyorgy Sandor, who was a student of Bartok's. Though Michele taught me piano rather than composition, maybe some quality of Bartok rubbed off, because I went on to write many short piano pieces for my students, in the spirit of Bartok's Mikrokosmos.

Similar lineages are traced in the world of mathematics. Jon Johnson, who's on the board of Friends of Herrontown Woods, sent me this link documenting Oswald Veblen's mathematical descendants. By this count, Veblen had 16 students and 10,126 descendants. The second number will steadily increase as descendants advise each new generation of mathematicians. The majority of Veblen's mathematical descendants can be attributed to three of his students, Alonzo Church, R.L. Moore, and John Whitehead. That Veblen played the advisor role for just 16 students must owe in part to his having left Princeton University to join the Institute for Advanced Study, which did not have the traditional advisory relationship between faculty and graduate students.

Taking a Step Towards Reuse


One central theme of the Veblen House project is reuse. This can be seen most obviously in the form of saving and repurposing a remarkable historic house, but also plays out in small everyday ways, like the salvaging and repurposing of this climbing wall. Part of a backyard play set, it was put out for the trash in my neighborhood. As it happens, there's a muddy stretch of trail between the Veblen House and cottage that could use a boardwalk, and this looked to be perfect for the purpose.

With the handholds removed, it was rolled into place on a wheelbarrow similarly rescued from the curb. Another piece was added, meaning that about 100 pounds less "stuff" got hauled to the landfill, and we no longer have to dodge the mud. It also saved the time and materials that a newly constructed boardwalk would have required.

Imagination and re-visioning stand between an economy's phenomenal productivity and a bulging landfill. Resourcefulness means fewer resources are needed to achieve the same result. The climbing board spent years offering a challenge to kids. Now it offers kids and adults easy passage over a former challenge. What more can we ask, really, from a boardwalk or from ourselves, than to change the world one step at a time?

Veblen House Hosts Rotary Club Youth Exchange Students

New experience, new friends, new spaces, new plants--that was the outcome of an afternoon spent on the Veblen House grounds with participants in the Rotary Youth Exchange Program. The Friends of Herrontown Woods teamed up with the Rotary Club of Princeton to play host to eighteen of the volunteers—from Belgium, Brazil, France, Germany, India and South Korea—all of whom are staying in the U.S. for a year with the help of four Rotary clubs in New Jersey.


My group bravely took on an intimidating stand of multiflora rose in the lower field, cutting back the tangle and hauling the thorny branches off to the woods. The object was to make room for some hazelnut sprouts rescued from a nearby construction site.


Metaphorically speaking, we took a couple lemons (a patch of invasive shrubs and a roadside hazelnut cut down to make way for a house) and made some lemonade,

and had some fun along the way. The eight hazelnuts have all since sprouted and are growing, protected from deer by some fencing.


Meanwhile, other students did some habitat restoration deeper into Herrontown Woods,
and cleared wisteria that had overgrown a the large circular stone wall where horses were once exercised next to the Veblen House. The cleared space within the horse run made a good gathering spot for a group shot. 

All in all, an exhilarating and productive afternoon. Thanks to all the students, and to the Rotary for making this possible.

A Beautiful Mind

The tragic loss of John Nash and his wife Alicia in an auto accident two days ago has prompted me to complete a post about the Veblen connection in Sylvia Nasar's book, "A Beautiful Mind". A good friend of Nash's, Jim Manganaro, had given me quotes from the book that mentioned the Veblens. We had often discussed my possibly talking to Dr. Nash, to see if he had any memories of the Veblens, but we didn't quite make it happen.


After a performance two years ago at McCarter Theater of "Proof", a play that explores the connection between genius and madness,

Sylvia Nasar took part in a panel discussion. Afterwards, I asked if she might still have notes from the research she did for the book, notes that could provide some insights about the Veblens. She didn't sound optimistic about easily finding them, but it's interesting to pull some quotes from the book relevant to the Veblens.

On the first page of Chapter 3, "The Center of the Universe", describing the scene Nash found when he arrived in Princeton after WWII, Nasar writes, "May Veblen, the wife of a wealthy Princeton mathematician, Oswald Veblen, could still identify by name every single family, white and black, well to do and of modest means, in every single house in town." It's an intriguing tidbit suggesting that Elizabeth Veblen, who instituted the tradition of afternoon tea at both old Fine Hall and the Institute for Advanced Studies, may have had a central role in the town's social fabric as well.

I had not encountered any other reference to Elizabeth Veblen as "May", though my notes, perhaps from talking to Nasar, say that May was the name of one of Henry Fine's sisters.


The third chapter continues with a wonderful description of old Fine Hall, "the most luxurious building ever devoted to mathematics". After Henry Fine's tragic death, as with John Nash due to a reckless car driver, the Jones family funded the building of the original Fine Hall, "designed by Oswald Veblen".

Describing all the contributions Turing and other mathematicians with connections to Princeton made to the war effort, Nasar writes that "Oswald Veblen and several of his associates essentially rewrote the science of ballistics at the Aberdeen Proving Ground."

"Princeton in 1948 was to mathematics what Paris once was to painters and novelists, Vienna to psychoanalysts and architects, and ancient Athens to philosophers and playwrights." This is the Princeton that Oswald Veblen had a central role in creating, a setting that attracted the likes of John Nash.

Nature/Culture Walk


On the premise that holiday weekends can sometimes have unexpected gaps, we're offering a nature and culture walk at Herrontown Woods--Sunday, May 24, at 1:30pm. Along with walking the trails and seeing what's growing, there will be talk of recent habitat restoration efforts and the mysteries of magnetism found in some of the boulders. Culture comes into play with the Veblen and farming legacies. Meet at the parking lot (it's down the short road across from Smoyer Park entrance on Snowden Lane).

The Rotary Club of Princeton includes the Veblen House at Herrontown Woods among its service projects. They're having their annual Pancake Festival fundraiser at Palmer Square this Saturday, May 23, 8am to noon. Money raised goes to community projects and scholarships. All you can eat--pancakes, fruit and bacon--for $10. Pre-K free.

A House as a Character in a Play

There's an extraordinary play at McCarter Theater in Princeton, continuing through this month, called Five Mile Lake. The five characters keep us spellbound for an hour and a half, but there's also a house that serves as a character of sorts. Like the Veblen House, it's a fixer upper in a beautiful natural setting. One character values the house, not only for its inherent value but also as the legacy of his grandfather, and puts time and money into fixing it up. His brother in the play values neither the house nor the past generation that left it in the family's trust. The Veblen project brings out that divide in perspective. In the play, the mending energy applied to the house takes on a metaphorical quality as the characters seek in each other a way to "come in from the cold".

Another fixer upper, with less prospect of repair, will figure prominently in the play that begins McCarter's new season in September, Baby Doll, by Tennessee Williams. Perhaps it can be said that all characters in plays, whether houses or human, tend to be fixer uppers.

Found Beauty--Springtime at the Veblen House


With the deep woodlands of Herrontown Woods to the west, and a small farm to the east, the grounds of Veblen House offer a transition, from field to forest and from english garden to native woodland. Though it's been decades since anyone has cared for Elizabeth Veblen's gardens, much remains. The two quince trees met their demise several years back, but the redbuds still put on an impressive show.

A clearing near the house is filled with Ajuga, a member of the mint family.


In another clearing, I found the first sprouts of ten native green-fringed orchids. I protected only one last year, having thought they might be nothing more than common lily of the valley. It grew instead into the lovely orchid, which spurred a visit this spring to protect more before the deer could find them.

In another flower bed, multiflora rose had displaced a portion of the remnant irises. Cut down during a Rotary volunteer day two years ago, the invasive rose was kept in check by the deer last year. We're leaving it as an experiment, to see if the deer do the same this year.



Earlier in the spring, daffodils made a beautiful display next to the small barn and corncrib, after FOHW board member Sally Tazelaar removed the thick tangle of multiflora rose that had grown over them.

Through all these acts, large and small, we reconnect with the love and energy that a previous generation invested in this special place in Princeton.

A Walk in the Woods for K-2 Students

There was lots to see as Denise Troxel's class of K-2 students left Stone Hill Church and headed into Herrontown Woods. We saw big beech trees with smooth gray bark that looked like the feet of elephants where they touch the ground, and the yellow flowers of spicebush just beginning to open. We saw the prickly "gum balls" of sweetgum trees, and jumped from rock to rock, root to root, when the trail got a little muddy.


Then, as we were crossing the little stream flowing out of the headwaters, we peered down into the clear water. What grabbed everyone's attention? One of the special things about Herrontown Woods is that a whole little section of the Harry's Brook watershed is preserved. We were in the headwaters, a big flat expanse that catches the rain and slowly releases it into the beginnings of a stream unspoiled by development. The steady supply of clean water provides habitat for a creature found nowhere else along the Princeton ridge--the marbled salamander.


The young salamanders were first discovered earlier this spring by Tyler Christiansen, a remarkable naturalist who was featured in the documentary "Field Biologist".

We also saw water striders walking on the water, and the tiny red flowers that had fallen from a red maple just upstream.

Then we headed off-trail, past boulders made furry and speckled by moss growing on them. Dodging an occasional wood briar with its little thorns, we found the woods otherwise open and easy to walk through.


The kids scanned the woods for a vernal pool like this one, made when rainwater fills the hole left by a tree toppled years ago by a storm. It's called a vernal pool because it holds water in the spring, then disappears in the summer. Because fish don't live in them, these pools make a good place for insects to live, and for frogs and salamanders to lay their eggs. We found a few that didn't contain much life. Maybe they dry out too fast to make a good home.



Then we found a vernal pool that had all sorts of life. Water striders dimpled the surface with their legs, predatory beetles scurried about.



We found a dragonfly larva, which didn't seem to mind posing on my hand for a minute, and a spider trying to walk on the water. Spotted salamanders, rarely found anywhere else in Princeton, had visited this pool weeks earlier and laid their white clusters of eggs.

And over in the corner were clusters of wood frog eggs, made green by algae that grow on the eggs and help supply them with oxygen.



After checking out the hole high in a tree where raccoons live, the students found the trail again and headed back towards Stone Hill Church, newly acquainted with some of their little neighbors living and growing in Herrontown Woods.

Stone Hill Church Volunteers Clear Old Barn Site


One of Herrontown Woods' neighbors is Stone Hill Church. Back when they were located on Westerly Road, their kids helped me periodically with habitat restoration at Mountain Lakes. Now that they've moved up to the ridge in northeastern Princeton, they've started helping in Herrontown Woods. Last year the Friends of Herrontown Woods helped them build a spur trail from the church into the preserve. Their trail is graced this time of year by spring wildflowers--trout lilies, wood anemone and rue anemone--with the fiddleheads of ferns just beginning to emerge.

This past weekend, I led thirty kids on an expedition from the church into the woods and over to the Veblen House to clear some invasives.

 On the way, we visited the cliff, then passed by the 19th century Veblen farmstead, then through the gate over to the Veblen House. This is the first year we could actually see the daffodils in front of the barn, after Sally Curtis cleared all the multiflora rose that had kept them hidden.

The goal for the kids was to clear privet and multiflora rose from the footprint of a larger barn that used to stand next to the circular horse run. The premise here is that if people can actually see the features around the Veblen House--the horse run, the remnants of the English garden Elizabeth Veblen tended, the barn footprint--it will be easier to appreciate the history and potential of the site. There's a curious story that a public employee used to sleep in the barn. After the barn burned down in the 1950s, they found a metal box containing his paychecks, which he apparently never cashed. That would have been an interesting lifestyle.


One of the more rewarding aspects of working with youth on invasive shrub removal is that they learn to work together. One will use a garden rake to push the thorny branches of a rose bush out of the way so another can duck under with loppers and cut the stems near the ground. Another then drags the branches off to the edge of the worksite. The roses grow in a very gangly way, so everyone has to be alert and aware of each other, to avoid getting accidentally pricked by a thorn. The aim is to get back to a more gentle nature--the expanse of ferns and wildflowers they saw next to their church, or the garden that once embellished the Veblen House.

One of the teenagers climbed a dogwood tree to liberate it from the clutches of a wisteria vine. The vine had originally been planted for a trellis next to the house. No doubt it was lovely, and fragrant, but when the house was boarded up, the wisteria undertook a kudzu-like expansion into the nearby woods.


Everyone approached the challenge of invasives removal in a different way. These girls used a bucket brigade method to transfer cut multiflora rose to a pile.

After several hours, and with half the barn's footprint now visible, the kids headed back through the woods to the church.

Thanks to everyone at Stone Hill Church for lending a hand at the Veblen House!

Veblen House History and Raingarden Tutorial at Updike Farmstead on April 4th

The Friends of Herrontown Woods and the Historical Society of Princeton are teaming up to present an indoor/outdoor program this Saturday, April 4, at the HSP home base: Updike Farm on Quaker Bridge Road. Come learn about the latest research on the Veblen House's history, the ongoing adventures of restoring Herrontown Woods over the past few years, and the logic of raingardens. And you can check out the Updike Farm, where renovation of the big barn is underway.

Here's the press release:

The themes of history and nature are featured in the special events offered at the Historical Society of Princeton’s April 4th Community Day at Updike Farmstead. Steve Hiltner, local naturalist, musician, writer and editor of the blog, Princeton Nature Notes, will lead three different programs to educate and inspire visitors.

At 1:00 PM -- Siting a Raingarden in Your Yard -- Raingardens are a popular, creek-friendly and attractive way to create habitat while filtering runoff from your house. Join a tour around the Updike farmhouse as Steve Hiltner discusses factors to consider when deciding where best to put a raingarden in your yard. Downspouts, sump pumps, air conditioners -- all will be discussed as potential sources of water to sustain a wildflower garden through droughts.

At 2:00 PM -- Preserving Oswald Veblen's Historic House and Legacy -- Oswald Veblen was a famous mathematician and visionary who was instrumental in bringing Einstein and the Institute for Advanced Study to Princeton. A "woodchopping professor,” he loved the woods, and founded Princeton's open space movement in 1957 by donating 100 acres for Herrontown Woods, Princeton's first nature preserve. He and his wife also donated their home and farmstead for a public purpose. A new nonprofit, the Friends of Herrontown Woods (FOHW), is seeking to acquire and restore this unique, historic house, and realize Veblen's vision. FOHW's president and co-founder, Steve Hiltner, will talk about the passion, sweat-equity and serendipity that has made the restoration of Veblen's Herrontown Woods such a rewarding experience.

At 3:00 PM -- Tree and Wildflower Walk --Learn about plants on this informal walk around the Updike Farmstead grounds to learn about the stately trees and plants growing along the fence lines of the property, including the giant red mulberry tree that bears delicious berries in June.

All programs are included with $4 museum admission. Updike Farmstead is located at 354 Quaker Road, Princeton. For questions, contact Eve Mandel, Director of Programs and Visitor Services, at (609) 921-6748 x102 or eve@princetonhistory.org.

An Ice Rink and Other Sculptures at Herrontown Woods

It was a sense of mission that caused us to venture into Herrontown Woods on a windy winter's afternoon so cold my hands were freezing up after just a few camera shots. But as often happens, once we got out there, we found plenty to appreciate. There were the tawny leaves held tight by beech trees, contrasting with the snow in the bright afternoon light. The snow we thought would slow our way had already been packed down by neighbors walking their dogs, and ground often wet in spring and summer was conveniently frozen hard.


This flat, densely wooded terrain, part of the Levine Tract preserved after the Veblens were gone, may not look promising for an interesting find.


But what's that mound rising up in the middle of an otherwise flat expanse north of the ridge?

Why, it's an ice rink, carved out of the rocky ground by a bulldozer long ago. Whether that was the intent is unclear. Might a homesick, bulldozer-driving Canadian have gone rogue a half century ago? If so, he correctly predicted that the water table would stay high enough in that area to insure seepage into the three foot deep, L-shaped cavity, and plenty of water to freeze in the winter. Nice math: Man + time + machine + hydrology + wintry weather = ice rink. It's all beginning to add up.

As you can see, the ice is thick enough to hold my daughter, a dog named Leo, and what appears to be an angel. After weeks of cold weather, the pond, which has no outlet, is probably frozen solid.

Next time, we'll bring a shovel and clear us a nice spot for that hockey game the mythic Canadian longed for.

Leaning over the water, all along the perimeter, are black birch trees whose buds begin to taste like wintergreen after a few seconds of chewing.

The beech tree leaves decorated our walk back, but there was still more sculpting to see.

Kurt showed me where he and Sally have been doing some habitat restoration around the sculpted features jutting out along the dramatic dropoff overlooking the Veblen cottage. Though the glaciers--essentially giant natural bulldozers--didn't quite reach our area during the last ice age, the powerful winds that blew down from them must have contributed to exposing these boulders.

And now Kurt, another force of nature, has been re-exposing the boulders by removing invasive shrubs from the steep slope. If they're too big to pull out, the Privet, Linden Viburnum, Honeysuckle, Multi-flora rose, and winged Euonymus are being cut down, improving prospects for the spicebush, blackhaw Viburnum, and other natives. This spring will mark the first time this dramatic geologic feature will be visible in decades.

Walking down the hill to the cottage and farmstead--a beautiful sight in a snowy landscape--we craned our necks to see the tops of the towering tulip poplars, where late sun was highlighting last year's array of tulip-shaped blooms still held tight in vaulted canopy.


On the way back to the parking lot, we saw some work by Herrontown Woods' sculptor in residence, the pileated woodpecker. Signature features are the size and vertical shape.

And the fresh woodchips on the snow suggested the work had been done earlier in the day.

Deep in the tree was the prize. Looks like carpenter ants to me.

Back home, we warmed our feet and hands next to the woodstove, as the Veblens certainly would have after an exhilarating winter's walk.
