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.

Autumn Reflections: The Majesty of Acer Rubrum

On a serene autumn afternoon by Beebe Lake, a solitary red maple stood out against the backdrop, showcasing its vibrant colors and resilience, symbolizing autumn’s fleeting beauty.

It was one of those serene autumn afternoons that linger in memory, the kind where the sky seems impossibly clear, the air crisp and gently scented with fallen leaves. I stood at the edge of Beebe Lake, my gaze first drawn to the textured concrete dam holding back the water, its weathered facade contrasting sharply with the soft reflections shimmering across the lake’s calm surface. Beyond, the wooded hillside rose gently, a tapestry woven with the warm hues of autumn—golds, greens, oranges, and reds mingling like brush strokes on a canvas.


An October Glory, turning before all others

Yet amidst this collective beauty, one tree captured my attention, singular in its brilliance—a solitary red maple standing proudly on the lakeshore. Its leaves had turned a vivid crimson, blazing brightly as though defying the muted earth tones surrounding it. Even from a distance, framed and partially obscured by larger trees, its vibrant reflection cast a fiery echo on the water, rippling softly in the afternoon breeze.

The maple, Acer Rubrum, seemed perfectly at home here, thriving robustly at the water’s edge. I remembered reading how adaptable red maples are, able to flourish in conditions ranging from dry uplands to swampy shores. This spot, near the edge of the tranquil Beebe Lake, seemed to showcase its resilient character perfectly.

Up close, the maple’s glow was even more striking. Its leaves cascaded in fiery clusters, hues deepening from bright scarlet at the tips to a darker maroon closer to the branches. This dramatic gradient seemed symbolic of autumn itself—beautiful, fleeting, and subtly tinged with the melancholy reminder of winter’s approach.

A memory surfaced of early spring in the Finger Lakes region, a time when maples, including this red maple, generously share their sap. Though not traditionally tapped like its sweeter cousin, the sugar maple, this species’ sap can indeed be boiled down into syrup, a surprising sweetness hidden within its sturdy trunk. Standing in its shadow, imagining those early spring days, it seemed astonishing that the same tree could offer both the delicate sweetness of syrup and the fierce beauty now on display.

Curiously, the transformation of the tree appeared methodical yet whimsical—it changed colors from the top down, its upper branches already bare, exposing slender twigs pointing skyward. Like an artist carefully removing layers to reveal something deeper beneath, the maple unveiled its upper bare bones first, as though reminding observers of the quiet strength supporting its autumn splendor.

This Red Maple (Acer Rubrum) turns from the top down and has already bare for most top branches.

As I lingered, taking in this turning tree, joggers passed by along the path, their rhythmic footsteps a gentle percussion beneath the rustling leaves. Briefly, they glanced toward the vivid maple, perhaps drawn, like me, by its striking contrast to the surrounding foliage. It felt like we shared a secret admiration for this singular tree, recognizing in it a quiet assertion of individuality amidst conformity.

Eventually, I viewed the maple once more from afar, framed now by broader sweeps of branches and leaves, partially obscured but no less vivid. Through layers of leaves and dappled sunlight, it glowed like a distant flame, a beacon that seemed to encapsulate the entire mood of the season—warm yet cool, bright yet transient.

The Red Maple (Acer Rubrum) is the first to flower in spring and the first to turn in autumn.

Walking away, the image of that maple lingered, its reflection shimmering gently in the afternoon sun, a moment suspended between summer’s lush vitality and winter’s bare stillness. Beebe Lake had offered scenic beauty, a quiet meditation, a reflection mirrored not only on its tranquil surface but in the heart of an observer captivated by a single tree’s fleeting glory.
