Exploring Sims-Jennings Preserve: A Nature Lover’s Delight

A walk through Sims-Jennings Preserve unveils ancient cliffs, vibrant bird calls, and the quiet wisdom of maples and waterfalls along Cayuga Lake’s forested edge.

I arrive early, the sun still climbing its slow arc, brushing the eastern sky in pastels as I step into the Sims-Jennings Preserve at Cayuga Cliffs. The trailhead, tucked neatly along NYS Route 34B, is a doorway into an ancient chapter of the Finger Lakes—one rich with the scent of moss, the hush of leaf-dappled silence, and the layered echoes of stone and birdsong.

The first thing that strikes me is the expanse of mowed meadow, rimmed with goldenrod and patches of milkweed. From here, the land rolled gently westward until it ends abruptly in cliffs that plummeted toward Cayuga Lake. A map at the entrance speaks of the Sherburne and Renwick Formations, shale and siltstone laid down when the land was covered in warm Devonian seas. The cliffs themselves stand like watchmen over time, protecting 4,000 feet of lakeshore from erosion, whispering tales older than mammals.

On the meadow edge is this Carya ovata, or shagbark hickory, unmistakable from its elongated leaflets and distinctive bark that peeled in long, curled strips. The leaves shimmered in the breeze, their green etched with pale speckles of recent rain, as if nature herself had hand-painted them.

I follow the yellow-blazed trail into a thicket where tall sugar maples—Acer saccharum—arched overhead. Their leaves caught the morning light, each palm-sized blade glowing like a shard of stained glass.



Throughout the preserve I find large holes like these in a pine tree snag, the work of a Pileated Woodpecker.

A sudden fluting note from the trees stops me in my tracks. “Ee-oh-lay,” the Wood Thrush sang, its call cascading through the forest like water over stone. Moments later, the rapid, accelerating trill of an Ovenbird joins in—a sound like “teacher-teacher-teacher” echoing from the understory. The forest is alive.

Watch on YouTube for the best experience.

I descend into the shade. A narrow stream runs over the flat gray ledges of the Ludlowville Formation, forming delicate waterfalls no taller than a man but intricate as lace. One fall, framed by a colonnade of black cherry and beech trees, poured over stone like a ribbon of silk. The water’s voice changed with each ledge—first a murmur, then a chuckle, then quiet confidence as it wound through the woods.

Here, a Scarlet Tanager flashes like flame through the canopy, its red feathers shocking against the sea of green. Above, the Eastern Wood-Pewee calles its own name from a high perch—“pee-a-wee”—a humble herald of summer. Lower down, a Tufted Titmouse flits from branch to branch, a gray blur with a whistle like curiosity incarnate.

Further along, a looping vine coils around a pair of trees like an ancient signature. Possibly a native bittersweet, its woody stem thick as a child’s arm. It reminds me of how all life here is entangled—flora, fauna, stone, and stream woven into one vast web.

I pause at the overlook, where the trail skirts the cliffs. From this height, the view opened to Cayuga Lake, vast and gleaming in the morning light. Across the water, the hills of the western shore softened into a watercolor horizon.

On the walk back, a robin sings its measured phrases from a nearby hawthorn, and I think how common birds often hold the deepest solace. The robin’s voice rises above the silence, not grand, not rare, but reassuring in its familiarity—like a good friend’s greeting.

I leave the preserve changed gently, like the soft indent of a footstep in moss. The Sims-Jennings Preserve at Cayuga Cliffs is a place that reminds you to listen. To the birds, to the trees, to your own breath. And in listening, you remember what it means to be wholly present in the world.

Thayer Preserve: Autumn Still Life 5

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.
