Stones That Traveled: Glacial Erratics, Deep Time, and the Stories They Leave Behind

Glacial erratics are immigrant stones—carried south by ice, dropped without explanation, and left behind to challenge our sense of permanence, place, and deep time.

There are rocks that merely sit where gravity has placed them, and then there are rocks that arrive with stories already embedded—foreign syllables carried south on ice, dropped without explanation, and left for us to puzzle over. Glacial erratics belong to the second category. They are migrants with no passports, refugees of deep time, whose presence quietly contradicts the landscape that hosts them.

Long before anyone reached for a hand lens or an ice-flow diagram, people answered such contradictions with imagination. In Ireland, a boulder perched just so on a mountain side is not a geologic problem but a resting place. Leprechauns, we are told, favor such stones—high enough to observe human intrusion, solid enough to outlast it. Skepticism, as folklore reminds us, is not always a stable position. Kevin Woods—better known as McCoillte—found that out the hard way when doubt collided with experience on the slopes of Slieve Foye. What followed was not merely a conversion story, but an act of modern mythmaking: folklore translated into bureaucracy, imagination petitioning regulation, and “The Last Leprechauns” entering the unlikely language of conservation. Stone, story, and belief hardened together into something oddly durable.

Rocks such as this are a favorite perch for leprechauns to rest and contemplate the works of man who have invaded their world. Inhabitants of Carlingford who wander Slieve Foye have come upon them often enough, their stories and certitude in the existence of the Little People are resistant to manifold doubters with their reasons and arguments. Kevin Woods, aka McCoillte, was a doubter until worked on a stone wall on property he owned on Ghan Road, Carlingford. His belief did not arise on the discovery of the leather purse, covered with ages of dust and lime, nor with the gold coins inside. McCoillte pocketed the coins for luck. As luck would have it, McCoillte loved to walk on Slieve Foye. It was on one such walk he and his dog encountered Little People who paralyzed them to escape. His unexplained absence led to troubles with the wife. This experience brought McCoillte around to enough of a belief that he, with lots of help, succeeded in petitioning the E.U. European Habitats directive to recognize leprechauns a protected species. A reserve was establish on Slieve Foye to protect the “Last Leprechauns” and you can google this phrase to learn more about McCoillte’s stories.

Back in the Finger Lakes, we tend to use a different grammar when confronted by an out-of-place rock. We name it, classify it, and trace its lineage northward. Erratics scattered across Tompkins County are geological sentences that begin somewhere else entirely. The bedrock beneath Ithaca—Devonian shale and sandstone—cannot account for crystalline intruders left behind like forgotten punctuation marks. These stones speak of ice sheets thick enough to erase valleys and decisive enough to transport mountains in fragments.

Some of those fragments have been domesticated. Cornell, for example, has never been shy about rearranging its stones. An unremarked erratic along the Allen Trail may once have been shrugged off as inconvenient rubble, while another—dragged from the Sixmile Creek valley—was carved into a seat and made eloquent. The Tarr memorial boulder, resting near McGraw Hall, transforms erratic stone into deliberate monument. It invites rest, contemplation, and perhaps gratitude for those who taught us how to read landscapes written by glaciers.

We find boulders of crystalline rock, commonly derived from Adirondack sources, left behind on the surface of ablation moraine, in the Finger Lakes Region. Cornell finds some and move them, maybe the case for this unremarked erratic found along the Allen Trail of FR Newman Arboretum. Another enormous erratic, brought in from the Sixmile Creek valley, was carved into a seat as a memorial to Professor R.S. Tarr who deciphered much of the glacial history of the Finger Lakes Region. Find it at the southwest corner of McCraw Hall on the Cornell University Campus. Reference: “The Finger Lakes Region: Its Origin and Nature,” O.D. von Engeln, Cornell University Press, 1961 page 106

Elsewhere, erratics remain defiantly themselves. In winter, one along Fall Creek alternates between anonymity and revelation, depending on whether snow smooths its surface or retreats to expose lichen constellations. Bridges pass overhead, traffic flows, semesters turn over, yet the rock remains unimpressed. It has already endured pressure sufficient to rearrange its crystals; a passing academic calendar is not likely to trouble it.

Then there are the stones that confront us most directly—those we stumble upon in fields, pulled from soil by plow or frost, demanding explanation. A white, iron-stained marble boulder in a Tompkins County field is not subtle about its foreignness. It does not belong to the local vocabulary of shale and sandstone. Its pale surface, crystalline texture, and mineral scars point insistently north, toward the Grenville terrane of the Adirondack Lowlands. The Balmat–Edwards–Gouverneur marble belt offers the most persuasive origin story: metamorphosed carbonate rock carried south by Laurentide ice, released when climate and physics finally lost patience with one another.

I found this white marble erratic in a Tompkins County field. The highest-probability source is Grenville marble from the NW Adirondack Lowlands / St. Lawrence County (Gouverneur/Balmat–Edwards marble belt), delivered by southward-flowing Laurentide ice. I say the most probable source is metamorphosed carbonate (marble) from the Grenville terrane to the north—especially the northwest Adirondack Lowlands / St. Lawrence County marble belt (the “Gouverneur Marble” and related Grenville marbles), transported south by the last Laurentide ice sheet. Why that’s the best bet: Ice-flow geometry favors a northern source. In the Finger Lakes, glacial ice advanced with a flow direction that was very close to due south, guided by the north–south bedrock valleys. Tompkins County erratics are “exotic” imports. Local bedrock around Ithaca/Tompkins is Devonian shale/sandstone, but the region contains many nonlocal (“exotic”) glacial erratics carried in from much farther north (including southern Canada and beyond). Marble isn’t local to the Ithaca area, but it is abundant in the NW Adirondack Lowlands. The Balmat–Edwards/Gouverneur area in St. Lawrence County is a classic Grenville Lowlands district with marble belts (the same province that yields cream/white building marble around Gouverneur).

What makes this particular erratic compelling is not just its provenance, but the improbability of its journey. Ice moved with purpose here, flowing south along bedrock valleys like Fall Creek and Cayuga troughs, turning the Finger Lakes region into a conveyor belt for distant geology. When the ice melted, it left behind evidence that refuses to blend in. Erratics are geological truth-tellers. They announce that this place was once unrecognizable, that what seems permanent is merely provisional.

Perhaps that is why folklore clings so naturally to stone. Whether leprechauns or Laurentide ice are credited, erratics insist on a larger frame of reference. They ask us to imagine landscapes in motion and beliefs under revision. A boulder can be a seat, a marker, a perch, or a puzzle—but never merely background. It waits, quietly confident, for us to catch up to its story.

Glacial Kettle Bog Wonders: Photographing Pitcher Plants at the O.D. Engeln Preserve in Freeville

Step onto Freeville’s O.D. Engeln Preserve boardwalk and meet purple pitcher plants in a glacial kettle bog—carnivorous beauty, hidden blooms, and macro-photo magic.

Seen from 1000 feet above in Google Earth, the O.D. (Von) Engeln Preserve at Malloryville Road lays itself out in two glacial “kettles,” pond and bog; a simple diagram drawn by ice and time, then complicated by everything that has happened since. In my photograph, taken from the bog observation platform on a July morning, the sky is rinsed blue, clouds billow, conifers stitch along the rim around open space. Step closer, or lower your lens, and the openness resolves into a crowded, intimate architecture of sedges and moss, twigs and standing water, sunlight and shadow.

I came here for a plant that does not announce itself the way wildflowers often do. The purple pitcher plant, Sarracenia purpurea, is a quiet scandal: a green vessel in a place where green should be satisfied simply to survive. I arrived equipped for attentiveness—an iPhone for the broad scene, and a Canon DSLR with the F2.8 100 mm macro lens for the stars of this bog. The macro lens is an instrument of humility. It forces you to admit that the important drama is often no bigger than your palm.

In earlier years, the pitchers could be found right where a visitor naturally looks—within the central cut-out of the observation deck, close enough to lean over and study. But the bog is not a museum display; it is a living negotiation. This season, highbush blueberries pressing in from the margin had crowded the pitchers out, pushing the flowering plants into the grasses eight to ten feet away. The shift is small in human terms, the kind of distance you cross without thinking. In bog terms, it is displacement—an erasure of a familiar scene, a reminder that rarity is not only about numbers but also about space.

The pitchers themselves—those “turtle socks,” as they’ve been nicknamed—sit at ground level in a rosette, their mouths open to weather. Sunlight floods the cups and turns them into something both domestic and uncanny: a set of green, veined slippers left out to air, or a cluster of small amphorae awaiting an offering. In the bog’s thin soil, nourishment is hard-won. The pitcher plant answers that poverty with invention. Instead of arguing with the chemistry of peat, it borrows from the animal world—luring and taking what the air can spare. The cup is a trap, yes, but also a reservoir: rainwater gathered and held, a miniature wetland that mirrors the preserve’s larger one.

There is a tension here that never quite resolves: the plant’s beauty, and the plant’s appetite. We admire the cup’s red veining, the glossy rim, the way the opening flares like a lip; then we remember what the lip is for. We admire the flower’s elegant sheltering forms; then we realize the shelter is also a funnel, a choreography. This is not cruelty—no more than winter is cruelty. It is adaptation made visible, a lesson in how form follows need, and how need can produce something unexpectedly lovely.

And yet the real marvel—the reason I came that day—rises above the traps on a strong stalk, lifted clear of the dangerous mouths below. The flower is not purple in the obvious way its common name promises. It is subtler and stranger: a suspended structure with the poise of a lantern and the protective logic of armor. It struck me as a flower unlike any I have experienced, resembling an insect carapace, with the reproductive element underneath a hood. That hooded design feels less like ornament than strategy—an architecture that guides a pollinator’s route, controlling entrances and exits the way the pitcher controls the fall of an insect.

Even the flower’s back side refuses to perform for the camera. From the posterior angle, “there are only bracts”—plain supporting structures, the botanical equivalent of scaffolding left in place once the facade is finished. The bog, too, shows its scaffolding everywhere: dead stems, old wood, peat-dark water, last year’s leaves. A preserve is never only what is blooming. It is what persists.

I found myself thinking about the details I wanted but could not quite capture that day: the downward facing hairs inside the pitcher—those one-way bristles that make retreat difficult once a victim has slipped in. I or my lens was not up to this challange. The shortcoming was minor, but instructive. The bog offers glimpses, not guarantees. It invites return visits, different light, different seasons, a different kind of patience.

Standing on the platform I felt the preserve’s central truth: these are landscapes shaped by constraint—by ice, by water, by nutrient scarcity, by the slow encroachment of shrubs—and yet they keep producing improbable forms. The purple pitcher plant is one of those forms: a green cup that drinks rain, a flower that wears a hood, a turtle sock that turns hunger into design. In a place where the ground itself seems to refuse abundance, the plant answers with a different kind of richness—an elegance that is also a solution.

Lookout Point, Ithaca, New York

The Erie Barge Canal significantly influenced New York’s history, particularly impacting Cayuga Lake and Ithaca. The canal, which extended to the Cayuga-Seneca canal, transformed Ithaca into a prosperous community due to shipping and salt production industries. Today, despite its shift from industrial uses to a leisure and educational haven, the canal’s cultural and economic legacy remains indelible on the town and lake.
