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.

A Late Winter Walk Through Cornell University Campus

Explore a late winter walk through Cornell University’s scenic campus, discovering blooming snowdrops, historic landmarks, and the striking “Magna Dancer” sculpture. Uncover the beauty and heritage captured in each step of this serene journey.


On the late winter afternoon of March 1, 2024, I decided to take a long walk starting from Cascadilla Park Road, making my way up through the Cornell University campus, and ending at Fall Creek near the Mundy Wildflower Garden before returning to my starting point. The sun was shining brightly, casting long shadows, and the crisp air was filled with a hint of spring. Carrying an Apple IPhone 14 Pro Max smartphone, I set off to capture the beauty and essence of this serene day.

Starting Point: Cascadilla Park Road

The walk began on Cascadilla Park Road, where I was greeted by a delightful patch of snowdrops (Galanthus nivalis) nestled among the glossy green leaves of periwinkle (Vinca minor). These delicate white flowers, blooming despite the chill, were a hopeful sign of the approaching spring. Their pristine petals contrasted beautifully with the dark, shiny leaves, creating a picturesque start to my journey.

These flowers were found in a garden on Cascadilla Park Road, Ithaca, March 1, 2024. Snowdrops (Galanthus nivalis) are among the first flowers to bloom in late winter and early spring, often pushing up through the snow. These plants are known for their nodding, white, bell-shaped flowers and are a common sight in gardens during this time of year. The glossy green leaves belong to a plant known as Periwinkle (Vinca minor). Periwinkle is a popular ground cover plant, often found in gardens due to its ability to spread quickly and form a dense mat of evergreen foliage. It typically has glossy, dark green leaves and produces small, blue or purple star-shaped flowers in the spring.

Climbing the Steps to Steps to Myron Taylor Hall

My path led me up flights of granite steps toward Myron Taylor Hall. As I climbed, I could feel the history and tradition of Cornell University enveloping me. The McGraw Tower bells chimed softly, adding a melodic backdrop to my ascent.

Discovering “Magna Dancer”

Reaching the top of the steps, I encountered, at the entrance to Hughes Hall museum, the striking “Magna Dancer” sculpture by Arline Peartree. Its bold red forms stood out vividly against the backdrop of the historic stone buildings. The plaque at the base provided a glimpse into its significance, commemorating the contributions of Cornell alumni. The sculpture’s dynamic lines and vibrant color injected a sense of modernity into the historic setting.

Winter Buds and the Robinson Herb Garden

Here, I passed through the Robinson Herb Garden, where the late winter buds of a Cornelian Cherry Dogwood (Cornus mas) were beginning to unfurl. These bright yellow clusters heralded the arrival of spring, standing out against the bare branches and muted tones of the garden. It was a reminder of the cyclical nature of life and the resilience of the natural world.

The tree in the photograph with the yellow buds is a Cornelian Cherry Dogwood (Cornus mas). It is one of the first trees to bloom in late winter to early spring, producing clusters of small, bright yellow flowers before the leaves emerge. Cornelian Cherry Dogwood is often used in landscapes and gardens for its early bloom and attractive appearance. This tree grown in the Robinson Herb Garden, Cornell University

Mundy Wildflower Garden and Fall Creek

At Mundy Wildflower Garden, a hidden gem nestled beside Fall Creek, the landscape transformed into a tranquil haven, with the gentle sound of water flowing nearby. Though it was still early in the season, the promise of blooming wildflowers lingered in the air. The garden’s carefully maintained paths and rustic benches invited quiet contemplation.

Exploring the Common Ferns Display

As I ventured further, I came across a display showcasing common ferns. The display included photographs and names of various ferns, such as the Christmas Fern (Polystichum acrostichoides) and Goldie’s Fern (Dryopteris goldiana). This educational exhibit was both informative and visually appealing, highlighting the diverse flora found on the campus.

Observing the Weather Station

Nearby, a weather station stood tall, equipped with various sensors to monitor climate conditions. A sign explained its purpose: to help understand how climate change is affecting plants in the area. The data collected here would provide valuable insights into the phenological changes occurring within the garden.

Traversing the Slope to Olin Library

Returning, I made my way toward Olin Library. The path took me along a steep incline, “Lib Hill,” where I could see the stark branches of deciduous trees reaching toward the sky. The steps seemed to stretch endlessly upward, mirroring the journey of knowledge that students undertake within the library’s walls. The modern architecture of the library contrasted sharply with the surrounding natural landscape, symbolizing the intersection of nature and human achievement.

Approaching McGraw Tower

As I neared the heart of the campus, the McGraw Tower stood tall and prominent, albeit encased in scaffolding for restoration work. The historic building, with its distinctive clock face, was an emblem of Cornell’s rich heritage. Despite the scaffolding, the tower retained its majestic presence, a testament to the ongoing efforts to preserve its legacy.

Returning to Cascadilla Park Road

As descended the hill, following Cascadilla Creek, reflecting on the six mile journey, I felt a profound connection to the enduring beauty and resilience of both nature and human creativity. The walk had taken me through time and space, from historic landmarks to natural wonders, each step revealing a new facet of the Cornell University campus.

Reflecting on History

My walk took me past a plaque commemorating the site of the first settlers’ log cabin in Tompkins County, built in 1788. The plaque, erected by the Cayuga Chapter D.A.R. in 1927, was a poignant reminder of the area’s deep-rooted history and the pioneering spirit that shaped it.

Frozen Fall Creek III

Across the years into a future

Gratitude for miracles witnessed is my emotion for this series, “Frozen Fall Creek.” Fifteen winters after Pam and I walked Fall Creek as a solid walking path, the stream flows without ice most years. My son, whose family now lives in the house, and his wife recalling walking the creek a few years ago, not in the past few years.

Weather records support our recollections and observations: here is an analysis of Ithaca January temperatures. The years 2009 through 2019 show a warming trend in daily temperatures for both minimum and maximum.

Analysis

Excel I used to plot minimum and maximum temperatures (Fahrenheit) for the 31 days of each January for eleven years 2009 – 2019. Click on the images of this post for a larger version.

Forecast

Pam and I moved to Ithaca 2011 and missed our Fall Creek winter walks, miss them even more now our weekend excursions are only memories. Here are January minimum/maximum average daily temperature projections from 2020 through 2044 based on the trend established from the 2009 through 2019 series. The trend is the solid color, projection the faded color.

Reading from the chart, if the current trend continues by January 2044 the average maximum daily temperature will be 47 degrees compared to 29 for 2009. In other words, the temperature never rose above freezing in the year 2009. By 2044 temperatures will be above freezing every day, on average, with daily minimums averaging 21 degrees.

From what I read, we can expect these warming trends to accerate within our lifetimes. My son named small mid-creek hummocks “islands” with numbers. Here is a view of his Second Island in late summer. What will Second Island be in 2044 late summer?

Frozen Fall Creek II

Natural Ice Sculpture

My last post, “Frozen Fall Creek I”, ended with macros of Ice Crystals on a bed of frost over creek ice within sight of our former home, a restored water mill. I continued on the ice, following the creek to this spot were the stream bed turns 90 degrees, changing from a southerly to a western flow.

Here I encountered an open course where constant water motion resisted freezing. A few frigid days later, the course had an amazing transformation.

Last To Freeze, Fall Creek

The transparent ice of the now frozen space retained the impression of movement, the surface rippled by current. In the following photograph, motionless ice crystals reveal the truth.

Ice Crystals on Water Frozen while Supercooled

In the intervening days, the constant motion resisted freezing while the water temperature dropped well past freezing to achieve a supercooled state. As the water temperature continued to drop, a fast transition from fluid to solid happened so quickly the movement of the water surface was preserved.
