Ithaca’s bedrock, formed 370 million years ago, deeply influences its landscape, neutralizes rainwater’s acidity, and carries a story of Earth’s resilience and transformation.
In Ithaca, New York, the story of the land is deeply rooted in its geology. Beneath the vibrant autumn leaves and along the path of Lick Creek lies a bedrock formed 370 million years ago. This ancient foundation, once the sediment of a vast inland sea, now forms the solid base upon which the city stands.
The bedrock here is a silent witness to Earth’s long history. Originating in the Devonian period, it marks a time when vast seas covered much of the Earth’s surface. Within these ancient waters, life flourished, leaving behind sediments that, over eons, transformed into the layered rock beneath Ithaca.
These layers are more than just historical records; they actively shape the landscape. The bedrock influences soil composition, affects plant growth, and directs the flow of streams. Lick Creek, with its clear waters, is one such stream that interacts intimately with this bedrock.
In autumn, the beauty of this interaction is vividly displayed. The red and yellow maple leaves create a striking contrast against the grey-blue backdrop of the bedrock, a blend of the vibrant present with the ancient past. These fallen leaves, over time, decompose and enrich the soil, continuing a cycle of life that this bedrock has supported for millions of years.
This bedrock also plays a crucial role in water chemistry. As acidic rainwater percolates through it, a remarkable transformation occurs. The bedrock naturally neutralizes the acidity of the rainwater. By the time the water emerges as streams, it is buffered to a neutral pH. This process is vital for maintaining the ecological balance of the area. The streams that flow out, including Lick Creek, support diverse ecosystems thanks to this natural filtration process.

The neutral pH water is crucial for the flora and fauna of Ithaca. It sustains the forests, the wildlife, and the natural beauty that defines the region. This water, once acid rain, purified by the ancient bedrock, now nurtures life in its journey.
In Ithaca, the bedrock is a testament to the enduring nature of our planet. It reminds us of the continuous cycle of transformation that defines the Earth. The contrast of the autumn leaves against the bedrock is not just a scene of ephemeral beauty; it symbolizes the dynamic interplay between the living and the geological, between the present and the deep past.
The bedrock of Ithaca, with its ability to neutralize acidic water, highlights the interconnectedness of natural processes. It shows how the Earth self-regulates and sustains life in intricate ways. As the buffered, neutral pH water of Lick Creek flows over this bedrock, it carries with it the story of a planet that is constantly renewing and sustaining itself.
In this landscape, the past is not just a memory; it is an active participant in the present. The bedrock, the autumn leaves, and the flowing streams tell a story of resilience, continuity, and the beauty of nature’s balance. This is the legacy of Ithaca’s bedrock, a legacy of endurance, transformation, and life.
A child and grandfather create lasting memories during a post-Thanksgiving leaf gathering ritual.
In the gentle embrace of the Finger Lakes region of New York State, the crisp post-Thanksgiving air is a mix of woodsmoke and the faint whisper of winter on the horizon. The earthy scent of fallen leaves, damp from the morning dew, begins to permeate the atmosphere, beckoning families outdoors to partake in the timeless ritual of leaf gathering.

The landscape is a canvas of russet and gold, painted by the hands of autumn. In one of the many serene backyards, framed by the skeletal silhouettes of trees now slumbering after their fiery display, a mound of leaves becomes the center of joyous activity. Here, a child, bundled in the cozy layers necessary to fend off the chill, is immersed in the simple, yet profound act of play. The leaves, a tapestry of oaks and maples, become her castle, her sea, her world to explore.
Her laughter rings clear, a melodic counterpoint to the rustling leaves as she is lifted high by loving hands only to descend into the crunchy embrace of her leafy playpen. A grandfather, his face etched with the smile lines of countless summers and autumns past, becomes the orchestrator of this joy. His flannel shirt, a patchwork of reds and greens, reflects the colors of the season, and his hands, weathered from years of tending to the earth and its cycles, now tenderly guide the child in her play.



The rake, usually a tool of labor, becomes a wand of magic, directing the leaves into heaps that rise and fall with each jump and dive. The child’s mittened hands grasp at the leaves, each one a different hue, a different shape, a different story. They fly up around her like a flock of birds taking flight, then settle back into their collective, creating a soft rustling symphony that speaks of the changing season.




As the sun begins to dip lower, casting elongated shadows across the yard, the child’s energy wanes. The vibrant activity gives way to tranquil moments of rest, with the child now lying still among the leaves, her eyes reflecting the vastness of the sky above, clear and blue, a window between the earthly and the infinite.
The day wanes, and the leaf-gathering winds down. A final tableau shows the child, now indoors, cocooned in the warmth of a blanket that mirrors the plaid of her grandfather’s shirt, the same colors now muted and soft. Her eyes are heavy with the weight of a day well spent, her dreams surely filled with the laughter and the leaves and the boundless love that turns even the simplest act into a treasure of memories.

This is the essence of leaf gathering in the Finger Lakes after Thanksgiving – not just the collection of what has fallen, but the gathering of family, of joy, and of moments that will be cherished and recalled long after the last leaf has been tucked into the earth’s winter bed. It’s a time when the harvest is not just of the land’s bounty but of the heart’s. Each leaf, a reminder that even as the world prepares to sleep beneath the snow, life is rich, full, and evergreen in the hearts of those who share it.

Hemlock Roots
Maple leaves and hemlock roots share an environment yet play distinct roles in the ecosystem. Maple leaves, broad and vibrant, capture sunlight. This process fuels their growth and contributes to the air we breathe. Each fall, these leaves turn yellow and brown, signaling a natural change. They fall, joining the forest floor. Here, they decompose, becoming part of the soil. This enriches the earth, supporting new plant life.
Hemlock roots anchor these mighty trees. Reaching deep into the soil, drawing up water and nutrients. These roots also stabilize soil, preventing erosion and are a network, unseen but vital, connecting the tree to its environment.
These natural processes have parallels in human generations. Like the leaves, each generation has its time in the sun. People grow, contribute to their world, and then make way for the next. The knowledge and experiences they leave behind enrich the lives of those who follow, much like fallen leaves nourish the soil.
Similarly, the hemlock roots parallel the foundational elements of human society. Traditions, cultures, and values are passed down, anchoring each new generation. They provide stability and nourishment, helping to guide growth and development.
Over time, just as the forest evolves through the cycles of leaves falling and roots growing, human societies change. Each generation builds upon the last, growing in the richness left behind. This ongoing cycle speaks to the resilience and interconnectedness of life, whether in a forest or in human communities.
In both nature and human experience, there is a rhythm of growth, contribution, and renewal. The falling of maple leaves, and the steadfastness of hemlock roots illustrate this beautifully, reminding us of the continuity and change inherent in all living systems.
color pallet
In the heart of nature, where Lick Creek flows, the land is a preserve. It guards the essence of the wild. Trees, tall and timeless, hemlocks, stand like sentinels. Their roots twist and turn, merging with the earth. Among them, maple leaves lie. They have journeyed from their branches to the ground. Yellow and brown, they rest. They carpet the soil, a patchwork of autumn’s farewell.
The creek murmurs. Its waters are a constant traveler, never still. They speak of journeys unseen. Along its banks, the leaves are at the end of their own journey. Melding with the earth, becoming part of something greater.
Here, time moves differently. It’s marked not by clocks but by the subtle shifts of nature. Leaves fall, waters flow, the trees stand watch. This is a cycle, ancient and endless. In this preserve, every element has a role, a purpose. Together, they create a harmony.
This place, where leaves fall and waters flow, is more than a preserve. It is a reminder. In nature’s embrace, everything finds its place. Everything belongs. Even as leaves fall, they find a new purpose. In their resting, they nourish. In their silence, they speak of life’s endless cycle.
Hartung–Boothroyd Observatory is a leading educational facility, aiding in the study of astrophysics, tracking asteroids, and fostering diverse academic collaborations.
Perched on Mount Pleasant in the town of Dryden, New York, the Hartung-Boothroyd Observatory (HBO) stands as a testament to the celestial curiosity that Cornell University has nurtured for decades. It is a gateway to the stars, a place where the heavens unfold in wondrous detail to the eyes of astrophiles and the lenses of powerful telescopes.
The observatory is home to a reflecting telescope, one of the largest in New York State dedicated to both education and research. This remarkable instrument, housed under a retractable dome, has provided students and researchers with direct experience in astronomical observations since its establishment in 1974.
HBO isn’t just an observatory; it is a bridge between the terrestrial and the cosmic. It represents an educational philosophy that values direct engagement with the subject of study. Undergraduates, graduates, and faculty members flock to the facility to engage in projects that range from studying variable stars and exoplanets to tracking asteroids. Here, theoretical astrophysics meets the tactile world, allowing for an integrated understanding of the universe’s complexities.

It is used mainly as a Cornell University (Ithaca, New York) teaching facility for upper-level astronomy classes. The observatory is named financial contributions of M. John Hartung ’08 (chemical industrialist and donor) and in honor of the labor of Samuel L. Boothroyd (founding professor and chairman of astronomy 1921–1942). The telescope construction began in the 1930s and the observatory was dedicated in 1974. It contains the James R. Houck 60 centimeter telescope and various instruments.

The James R. Houck telescope at HBO was a project initiated by its namesake in 1972, using optics and a lightweight tube which had been fabricated in the late 1930s by Samuel T. Boothroyd, Cornell’s first astronomer, and a mounting constructed by George Gull ’72 as his senior design thesis in Mechanical Engineering.

The telescope, control electronics and instruments are largely the result of work done by undergraduates since 1970. It was manufactured by the students at the Tompkins, Tioga and Seneca BOCES and by Therm, Inc., with mirror coatings by Evaporated Metal Films corporation, all in Ithaca. The latter corporation was founded by members of Boothroyd’s scientific team, as he pioneered the use of evaporated metal coatings in astronomical optics. The telescope and observatory were dedicated in 1974.

The primary mirror is made of Pyrex from the Corning Glass Works and is in fact from a 1/8-scale test pour by the Corning company in preparation for the making of the 200″ Palomar mirror. It is 0.635 m (25 inches) in size, but the outer half inch is masked. The focal length of the mirror is 2.5m (100″) or f/4.

The Cassegrain design of the James R. Houck telescope is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes, the main characteristic being that the optical path folds back onto itself, relative to the optical system’s primary mirror entrance aperture. This design puts the focal point at a convenient location behind the primary mirror and the convex secondary adds a telephoto effect creating a much longer focal length in a mechanically short system.

The secondary is an 8″ mirror made of Cervit (a low thermal coefficient material). In combination with the primary, it yields a final f/13.5 beam to the nominal focus, which lies 18.5″ behind the primary mirror’s vertex. At nominal focus, the plate scale is about 24 arcsec/mm, with an effective focal length of 8.57 m.

The latter corporation was founded by members of Boothroyd’s scientific team, as he pioneered the use of evaporated metal coatings in astronomical optics.
The dome itself, like all professional observatories, is unheated. The telescope and instrumentation can be controlled from a neighboring control room which is heated and offers standard amenities plus several computers for simultaneous data reduction.
The observatory was founded by James Houck and managed by him through 2006. The principal contact is Don Barry, who managed the facility from 2006-2015, and taught Experimental Astronomy using the facility.
“Graduates” of the HBO project are now senior engineers and technical managers as well as graduate students, research associates and faculty at major universities.
Moreover, the observatory is a beacon for interdisciplinary collaboration. It’s not uncommon to find astronomers working alongside computer scientists, engineers, and educators. This cross-pollination of ideas enhances the potential for innovation, fostering new techniques in data analysis, instrument design, and educational methods. The observatory’s role extends beyond its primary function; it is a hub of convergence for diverse academic disciplines, all under the umbrella of exploring the unknown.
HBO also contributes to the global astronomical community through its research. The data collected here feed into larger networks of observation and analysis, aiding in the collective endeavor of mapping and understanding the universe. Its strategic location in upstate New York, away from the light pollution of large urban centers, grants it relatively clear night skies, making it an invaluable resource for both optical astronomy and astrophotography.
In an era where space exploration has captured the public imagination like never before, observatories such as the Hartung-Boothroyd are more crucial than ever. They serve as terrestrial launchpads, propelling minds into the realm of scientific inquiry. Here, the vastness of space becomes approachable, the mechanics of the cosmos decipherable, and the mysteries of the universe a little less mysterious.
As the night falls and the stars emerge, the Hartung-Boothroyd Observatory continues its silent vigil over the heavens. It stands as a beacon of knowledge and discovery, an educational catalyst, and a gateway to the stars. For the students and astronomers who work from this dome on Mount Pleasant, HBO is more than an observatory—it is a vessel navigating the infinite ocean of the night sky, a journey that begins in the heart of Cornell University and extends to the edges of the observable universe.
An 84-degree October walk up Cascadilla Gorge—quiet paths, bluestone porches, fresh paint on the bridge—waiting for the footbridge to catch the last, warm evening sunlight.
Every fall I make a point of walking Cascadilla Gorge at least once. On an 84-degree October 9 afternoon, Pam was tied up with chores, so I parked downtown and stopped to see the grandchildren. They were with their mom. Two were “too tired” after school to do anything. The youngest, at the age of four, was not yet in school and he floated the idea of the skateboard park; for me, that wasn’t in the cards. So I set off on foot up Court Street, past the residence of Buddhist monks at the gorge entrance.
Cascadilla Gorge is part of Cornell Botanic Gardens (formerly the Plantations), the university unit that stewards natural areas and gardens across campus. Foot traffic was light. A sign explained why: the lower trail was closed at Stewart Avenue, where the bridge spans the ravine. I crossed to the north side by the Christian Science church and wound up Cascadilla Park Road to the rim trail that climbs East Hill toward campus.
Homes line this stretch, porches facing the gorge where the constant music of creek and falls carries up. Not feeling ambitious, I made a few phone snapshots. Here the path squeezes past a porch built of local “bluestone,” a feldspathic sandstone native to the region—around town it’s sometimes called “Llenroc,” Cornell in reverse.

That pot you see in the previous photo gets a closer look here, with more of the same weathered bluestone.

The drop to the gorge floor is steep, sheer in places. The barrier fence looks stout in some sections and thins to almost nothing in others. A few years ago, a recent Cornell graduate walking home late along this path fell to his death. I continued to the fork for the Ithaca City Cemetery, climbed to Stewart Avenue, turned right to cross the Cascadilla bridge, then right again onto the Gorge Rim Trail back toward town. At the bridge I noticed part of the closure work: fresh paint on the bridge and on the suicide-prevention netting beneath. On September 24—just fifteen days earlier—a Cornell senior had jumped; the net caught him, and the fire department brought him to safety.

From the concrete barrier in that photo you can peer into the gorge: a beautiful view, the steady voice of water rising from below. I try to leave the darker stories where they belong—at least until the sight of fresh paint pulls them back to mind.

I took the following photograph in 2005, the September before my previous post, “Autumn Stroll in Sapsucker Woods” with the Kodak DSC pro slr-c, an ND filter, 50 mm lens and a tripod. It was a planned session, I work waterproof boots and was able to stand in the creek after a series of rain-free days. At this time of the year the gorge opens to the setting sun. I waited, taking a series of photographs for the perfect amount of light on the footbridge. The feature photograph (the header to this posting) is a detail from a shot with the bridge more fully lit.
The header image for this post comes from a planned session in September 2005, just before the photograph of my “Autumn Stroll in Sapsucker Woods” post. I used a Kodak DCS Pro SLR/c with an ND filter, a 50 mm lens, and a tripod. After several rain-free days I wore waterproof boots and stood mid-creek. In autumn the gorge opens to the setting sun; I waited and shot a sequence until the light laid perfectly across the footbridge. The banner image is a detail from a frame where the bridge is more fully lit.
We have a framed print of that photograph at home. I mounted it as a gift to Pam on our first Valentine’s Day.
If you’ve walked Cascadilla Gorge in autumn, I’d love to hear your favorite vantage points—porches along the rim, the lower stone steps, or the footbridge at golden hour. Do you know any stories about Llenroc bluestone on these houses, or remember the Stewart Avenue Bridge before its safety upgrades? Photographers: what helps you balance deep shade and bright water from the designated trails? Share a tip or a memory in the comments.
