Cornell Botanic Gardens’ Monkey Run: History, Geology, and Scenic Fall Creek

A contemplative walk along Monkey Run where Fall Creek writes the valley’s history—sycamores, bridges, and Devonian stone speaking across seasons in Cornell’s living classroom.

On a morning in late March, when the hills about Ithaca still hold the night’s frost in their shaded folds, I took the path called Monkey Run and went to see how Fall Creek spends its winter earnings. The air had the bright sting of thaw, a kind of vernal austerity that keeps a man honest in his steps. Along the high bank the sun spilled its coin onto the water, where it broke and flickered like a school of silver minnows. A rim of snow clung to the shale ledges, and the leaves of last year’s oaks—curled, fox-red, and faithful—whispered as if to keep the woods awake until spring fully claimed them.

Monkey Run is one of the outlying parcels tended by Cornell Botanic Gardens—once called the Plantations, and now, more fittingly, named for the living charge it keeps. These gardens do not end at beds and borders; they encompass the wilder rooms of the county, more than a thousand hectares of glens, pastures, and ravines where the university’s first and oldest teacher—nature herself—still holds class. Fall Creek is one of her principal lecturers. Rising beyond the high country of Cayuga Heights and slipping under stone and snow, it shoulders its way across the campus, idles a while in Beebe Lake, and turns turbines of memory at Triphammer Falls before shouldering on toward the lake that receives nearly everything here—Cayuga—long, deep, and glacial in its thinking.

If you would learn a valley’s mind, walk a meander. The creek here composes with easy cursive, laying down a bar of gravel, nibbling at a bank of clay, then sweeping back to consider its work from the opposite shore. The geologist says the rock is Devonian, pages laid flat and damp with time, and the ice of ten thousand winters ago scoured them into the open. A creek is a patient mason, working without rest and never in anger. I admired these sycamores—their clean bones shining through the leafless canopy like the ribs of an old cathedral. Winter reveals their whiteness; summer grants them shade. A stand of white pines keeps a dark counsel in the background; on the muddy edge, green tongues of skunk cabbage push up, pledges made by the swamp to keep faith with the sun.

I came down to the water near an old steel pier, a bridge remnant, hanging on each end without purpose. It wears graffiti the way a boulder wears lichen; human wishes, briefly rooted, coloring what they can. The river accepts it all, the pilings and the scribbles, the cast limb and the bottle’s glint, and continues its one unarguable gesture downstream. That is the old instruction of Fall Creek: use, refuse, endure. Before the university drew students from every quarter, the creek turned wheels and powered the small ambitions of a frontier town. Even the name Triphammer speaks of iron struck to purpose. Now the water powers something quieter: the studies of herons, the almanacs of kingfishers, the quick arithmetic of minnows over limestone.

Looking back while climbing the steep bluff

Steps cut from logs ascend the bluff, each tread pegged with iron, each rise a short confession of breath. I climbed to the ridge, paused halfway, and through the gray lace of March branches saw the creek shining at a bend far below. A man cannot help but measure his own life against such a course. The path goes up and down in obedient red blazes, but the water keeps its own counsel. Where the bank slumps the river shoulders through; where the bottom rises it lays down a mirror. In my youth I wanted the straight run, the short work. Now the curve pleases me. To go with the current and not be carried away—that is a lesson suitable to the grey in my beard.

When I returned five months later, on August 23, the same path had forgotten the word austerity. The cathedral of sycamore was fully leafed, the white pillars now vanished behind a nave of shade. The pines perfumed the air without trying. A new footbridge—clean timber arching like a bent bow—spanned one of the wet flats. Its braces, black-bolted and handsome, looked as if they would hold the weight of an ox team or a file of schoolchildren. Such crossings are a kind of promise from the present to the future: we found a way through here; may you, too. Below, the floor was upholstered with moss, oak leaves, and a scatter of pinecones—the slow currency of the woods accumulating interest.

Summer makes a confidant of every plant. Ferns unrolled their scripture at the bridge abutment; jewelweed held its tiny lanterns along the seeps; a kingfisher rattled downstream, blue lightning with a bill. The creek, glassy over its shale pavement, showed every wrinkle of its stride. I waded a little, feeling with the sole what the eye could not—where the current took an extra thought around a stone, where it forgot itself in a warm eddy. Trout lingered in the dimmer reaches, quick as commas; a great blue heron lifted off with that surprising tidiness of wing, ungainly only in our imagination.

In all seasons the trail carries two histories: one written in rock and water, the other in the footfall of people. Cornell’s founders, Ezra and Andrew White, believed the university should place the hand near the thing studied; here that principle is plain. Botany students take their lectures in leaf and bark; geologists read the creek banks as if the pages might soon turn by themselves; children learn the oldest calculus—how long a stick will float before it catches in the weeds. The caretakers from the Botanic Gardens mark, mend, and interpret, but they do not overtalk. The woods speak enough.

As the afternoon eased toward evening, I climbed once more to the bluff. The light had gone honey-colored and the leaves of the maples, those careful accountants of September, were just beginning to weigh their green against gold. I looked down on the bend where I’d stood in March—cold, bright, expectant—and felt the year’s circle gently close. As John Burroughs wrote, “The power to see straight is the rarest of gifts… to be able to detach yourself and see the thing as it actually is, uncolored or unmodified by your own… prepossessions… that is to be an observer and to read the book of nature aright.” Monkey Run obliges that humility. The creek moves as it always has—glacially taught, mill-forged, campus-wise, and freedom-loving—and the trail, with its modest stairs and honest bridges, invites us to walk beside it, to match our breath to its turnings, and to leave, if we can, a lighter trace than we found.

Beauty and Struggle: Flowering Rush in Stewart Park

Crossing the footbridge in Stewart Park, I encountered the graceful yet invasive Flowering Rush. Its delicate beauty hides a deeper story about nature’s resilience, human impact, and the fragile balance of our ecosystems.

While crossing the suspension footbridge over Fall Creek in Stewart Park, there’s a sense of stepping into a world that’s more peaceful and attuned to nature. The bridge is familiar to me—a steady, quiet companion—but each visit feels new, as though the park has secrets it only reveals in small whispers. In this photograph the green steel beams rise like sentinels, standing tall against the backdrop of shifting autumn colors. Below, the water reflects the vibrant reds, golds, and greens of the trees, creating an illusion of depth that draws me in.

Footbridge to the Fuertes Bird Sanctuary, Stewart Park, Ithaca, New York, October 2012

This past summer I stopped midway across, leaned against the railing, just listening. The creek moved slowly, like time itself decided to pause here for a while. That’s when I saw them: delicate pink blooms rising up from the water’s edge, their petals small and star-shaped, catching the light as they sway in the gentle breeze. There’s something striking about these plants—graceful, elegant, almost otherworldly in their simplicity. They reach up, as though trying to escape the confines of the water and the muddy banks.

My subsequent research revealed these to be Flowering Rush, or Butomus umbellatus. I often see them now, their soft pinks and slender leaves creating a quiet beauty that’s hard to ignore. They’re beautiful, but I have come to know they don’t belong here. This is one of those moments in nature that gives me pause—a reminder that not everything lovely is innocent.

Flowering Rush Growing in Fall Creek, Stewart Park, June 2024

Flowering Rush, a European import from centuries ago, was not meant to take root here. Brought to North America for ornamental ponds, its allure quickly became its danger. It spread, silently, like a secret carried on the wind, slowly overtaking the native species that have long called these waters home. And yet, standing here now, I cannot help but admire its tenacity, its quiet determination to thrive. Nature, in all its forms, has this incredible will to survive, even if that survival sometimes comes at a cost.

My mind drifts to the plant’s history. In its native lands Flowering Rush, or Grass Rush, was useful—its roots, though bitter, were harvested for food, and its fibrous stems woven into mats and ropes. How interesting that something as delicate as this has a rugged, practical side. This contradiction makes perfect sense when I think of the plant’s journey across continents, carried over oceans by human hands and curiosity. We are responsible for its presence here, and now, like so many other invasive species, it’s become a fixture of this landscape.

I think about the dual nature of this invasion. Flowering Rush is beautiful—there is no denying that. Its soft, pink flowers contrast sharply with the darker tones of the water and the dense green of the grasses that surround it. But its beauty masks a quiet destruction. It chokes out the native plants that once thrived here, altering the ecosystem in ways we cannot always see. I wonder what fish and aquatic life struggles beneath the surface, their food sources slowly disappearing. What birds find fewer insects and fewer safe places to nest?

And yet, is this plant a villain? Flowering rush is doing what it was meant to do—grow, spread, survive. That is what everything in nature does, after all. It does not have malice or intent; it just is. It is humans who have changed the balance, who introduced this species to a place where it didn’t belong, setting off a chain reaction we’re still trying to fully understand.

Today, as I walk across the bridge, heading toward the Fuertes Bird Sanctuary, path ahead invites quiet reflection, the chirping of birds and the rustle of leaves providing a peaceful soundtrack. But the Flowering Rush lingers in my mind. It reminds me of how interconnected everything is, how one small action—a plant brought from a distant land—can ripple out and affect entire ecosystems. It’s a lesson in responsibility for those willing to listen.

As I step into the sanctuary, the air feels lighter, filled with the sound of birds that dart between the trees. I think of the delicate balance of life here, and how easily it can be disrupted by the presence of something foreign, something invasive. Yet, there is a strange comfort in knowing that nature, for all its fragility, has its own resilience.

The Flowering Rush, with its roots deep in the muddy banks of Fall Creek, is a testament to that resilience. It may not belong here, but it has found a way to adapt, to make this place its home. And in that, I find both a warning and a kind of hope—hope that we, too, can learn to live more thoughtfully, more in tune with the world around us, before we upset the balance any further.

For now, though, I simply walk, grateful for the beauty around me, even if it comes with complications. Each step takes me deeper into this world, and I am reminded once again of the profound connection we have to the land, the water, the plants, and the creatures that share this space.

Late Autumn Ithaca 7

Hillside Rest

We pick up this walk through Ithaca from the December 23rd post, next to a waterfall and the “Theory Center,” starting with the spiffed up rear façade of the Cornell Health Building, renamed from Gannett Health after a right wing newspaper publishing magnate. The building fronts “Ho Plaza” thus carries an address with unfortunate allusions, named for a distinguished Cornell alumna who’s family name is Ho. I included this building in appreciation to Cornell University and students for being good neighbors during this COVID-19 pandemic, controlling the virus.

Today, I avoided the views of the popular Lib Hill to minimize personal contact. Instead, descending the hill on footpaths, found myself on Stewart Avenue and the eastern side of City Cemetery.

Enjoying the solitude and long shadows of our northern afteroon.

Traversed a gate of hemlock branches….

Admired random monuments. By the way, George Washington Schuyler, whose family anecdote I shared in a previous post, rests here under an impressive stone. Not this one.

More afternoon light, fallen leaves, hemlocks.

Late Autumn Ithaca 5

Golden Hour and “Happy New Year”

Walking the Lower Cascadilla Gorge Trail from the end of Court Street, downtown Ithaca, named for the Tompkins County Court is a favorite way for students to walk from the Cornell Campus.

I avoided the route today, the trail is narrow, much less than the 6 foot minimum distance. The footpath from Eddy Gate to College Avenue passes where the trail climbs up from the gorge. I did opt to catch the Upper Cascadilla Gorge trail, much wider. The trail passes two footbridges accessing the Engineering Quadrangle and the main Cornell Campus. Photographed here is the approach to the second, smaller, footbridge.

Late fall/winter afternoons the “Golden Hour” is hours long for this view of the footbridge and waterfall.

Waterfall views from the bridge. I left the tripod at home, so these exposures “freeze” water motion.

Look up from the other side for this view. Baptized 1985 as “The Theory Center,” 2007 saw the name changed to the more evocative, “Center for Advanced Computing.” It always filled with supercomputers. Socially, the culture of the place was retrograde from the beginning with “faculty only” lounges that kept out the lowly staff members. As if on cue, I came upon a group of the privileged, unmasked, strutting down the hill toward me, like vacuous moles.
