In the dappled sanctuary of the woodlands, where the rustle of leaves is a constant whisper and the breeze carries the secrets of the earth, there lies an unspoken harmony between the realm of the rooted and the realm of the roving. Here, the art of shelter is not just necessity but poetry—a dialogue between man and nature, bird and branch, leaf and sky. It is in the woodland shelters—those humble lean-tos and the charming birdhouses—that this conversation finds its most enchanting expressions.

A lean-to, a simple structure, a slant of sanctuary against the embracing trunk of a venerable oak or the crook of a steadfast pine, rises like an ode to minimalist refuge. It is both a testament to human ingenuity and a bow to the grandeur of the forest. Constructed from the very bones of the woods, with limbs that have fallen in the last tempest’s dance, it is clad in the textures of the wild—a tapestry of bark, a patchwork of leaves. It does not impose but rather suggests, whispering, “Here, rest awhile, where the earth holds you and the canopy cradles the sky.”

Within this woodland embrace, the lean-to is the hermit’s haven, the hiker’s pause, the dreamer’s alcove. It is the place where one can commune with the murmur of the brook, the chitter of the squirrel, and the silent flight of the owl at twilight. It is here that the smoke of a small fire mingles with the mist of dawn, where stories unfold to the rhythm of the crackling embers and the forest listens.

And what of the birdhouses, those quaint dwellings that pepper the woodland tableau? They are not mere shelters but the grand stages for the aerial ballet of wings and the morning serenades of feathered minstrels. Each is a mansion of possibility, an invitation etched in wood and lovingly placed among the boughs. They are the outposts of avian dreams, where the pulse of tiny hearts beats in time with the dripping of rain and the warmth of the sun’s caress.

The birdhouse is a symbol of the generosity of the woodsman’s spirit, a gift to the skyborne, a token of respect to the delicate denizens of the firmament. Here, the chickadee, the finch, the nuthatch, and the wren find respite and nurture the next generation of sky dancers. Each hole is a portal to a home, each perch a threshold to the warmth within, and every departure and return is witnessed by the vigilant trees, the silent sentinels of the forest.

Lean-tos and birdhouses, these woodland shelters, are the chorus of the sylvan symphony, the unseen chords that bind human to habitat, life to life. They are proof that in the quiet places of the world, where humanity treads lightly and the wild holds sway, there can be a beautiful coexistence, a mutualistic masterpiece painted on the canvas of the wilderness. They stand as symbols of the beauty that arises from the marriage of function and form, purpose and aesthetic, the innate and the crafted.

In the woodland shelters, there is a rhapsody played in the key of nature—a song of simplicity, of connection, of the perpetual dance between the earth and its many children. It is here, in the lean-tos and birdhouses, that the heart of the woods beats strongest, beneath the watchful eyes of ancient trees and the endless sky.

Gateway to the Universe

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.

View south

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 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 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.

Ferns, ancient plants with unique reproduction strategies and ecological significance, adapt to diverse environments while contributing to overall biodiversity and human culture.

In the vast tapestry of the plant kingdom, ferns occupy a unique and enduring place. These ancient plants, often overlooked in favor of their flowering counterparts, have a fascinating and seemingly eternal existence that spans millions of years. Ferns, with their lush green fronds and distinctive reproductive mechanisms, offer us a glimpse into the enduring legacy of life on Earth and the remarkable adaptations that have allowed them to persist through the ages.

Ferns belong to the group of plants known as Pteridophytes, which evolved more than 360 million years ago during the late Devonian period. Their evolutionary history predates the appearance of flowering plants, making ferns some of the oldest living organisms on our planet. This remarkable longevity raises the question: how have ferns managed to survive and thrive for so long?

One key to the success of ferns lies in their unique reproductive strategy. Unlike flowering plants that produce seeds, ferns reproduce via spores. These small, dust-like structures contain the genetic material necessary for ferns to reproduce. When mature, ferns release spores into the environment, where they can be carried by the wind or water to new locations. Once a spore finds a suitable environment, it can germinate and develop into a new fern plant.

The spore-based reproduction of ferns is not only ancient but also highly efficient. It allows ferns to colonize diverse habitats, from moist, shaded forests to arid deserts. Additionally, ferns can form extensive networks of underground rhizomes, which are creeping stems that give rise to new fronds. This vegetative propagation further contributes to their resilience and adaptability.

Ferns have also developed a range of adaptations that enable them to thrive in various environmental conditions. Some fern species, such as the resurrection fern (Pleopeltis polypodioides), can endure extreme desiccation. When conditions are dry, these ferns curl up and appear dead, but they can quickly revive and unfurl their fronds when moisture returns. Backpacking through mountainous Arizona wilderness I encountered small ferns growing in the shade of rock ledges, maybe this was Phillips Cliff Fern (Woodsia phillipsii). My guide called it “Ridgeline Fern” and claimed it was important for desert survival, could be eaten in extremis situations. This remarkable ability to withstand drought and promote human survival is a testament to the tenacity and usefulness of ferns.

Another intriguing aspect of ferns is their mutualistic relationship with mycorrhizal fungi. These fungi form symbiotic associations with fern roots, aiding in nutrient absorption and enhancing the fern’s ability to thrive in nutrient-poor soils. This partnership has likely contributed to the fern’s ability to colonize a wide range of habitats and compete with other plant species.

While ferns have proven to be resilient survivors, they have also played a crucial role in shaping Earth’s ecosystems. Ferns are often early colonizers in disturbed or newly formed habitats, and their presence can help stabilize soils and create conditions suitable for the establishment of other plant species. In this way, ferns contribute to the ecological succession and overall biodiversity of ecosystems.

Beyond their ecological significance, ferns have captured the human imagination for centuries. Their delicate and intricate fronds have inspired art, literature, and even garden design. Many garden enthusiasts cultivate ferns for their ornamental beauty and unique charm.

In conclusion, the eternal life of ferns is a testament to the remarkable adaptability and resilience of these ancient plants. Their longevity, dating back millions of years, serves as a reminder of the enduring nature of life on Earth. Ferns have evolved unique reproductive strategies, adaptations to various environments, and mutualistic relationships that have allowed them to persist and thrive. Whether they are serving as pioneers in newly formed habitats or gracing our gardens with their elegance, ferns continue to capture our fascination and enrich the natural world. Their legacy reminds us of the intricate and interconnected web of life that has persisted on our planet through the ages.

Dappled Sunlight

The Malloryville eskers near Freeville, New York, highlight the region’s glacial history and contribute significantly to biodiversity and local ecology.

Walking here, I enjoy telling the grandchildren of the immense, mile-high ice sheet that once covered this land 10,000 years ago, creating these hills and hollows.

Click Me for another Malloryville post, “Formed By Water.”

Eskers are geological features that tell a rich tale of the glacial history of an area. In the landscape near Freeville, New York, the eskers of Malloryville stand as prominent reminders of the last Ice Age and the profound effects glaciers have had on the North American terrain. These elongated ridges, composed primarily of sand and gravel, not only offer a visual spectacle but also provide crucial insights into the glacial processes that shaped the region.

Eskers are formed by the deposition of sediment from meltwater rivers flowing on the surface of or within glaciers. As these glaciers recede, the sediment accumulates in the paths previously carved by the meltwater streams, eventually forming ridges. The Malloryville eskers are particularly notable for their well-preserved structure, giving geologists and enthusiasts alike a clear vision of the patterns of glacial meltwater flow from thousands of years ago.

Located just a few miles from Freeville, the Malloryville eskers are an intriguing natural attraction. The topography of the area, largely shaped by the Laurentide Ice Sheet during the last glacial maximum, is characterized by various glacial features, but the eskers are undeniably some of the most distinct. Their serpentine-like appearance, weaving through the landscape, immediately captures one’s attention and beckons further exploration.

From an ecological perspective, the eskers of Malloryville contribute to the area’s biodiversity. The unique microenvironments created by these ridges offer habitats that differ from the surrounding landscape. This differentiation allows for a variety of plant species to thrive, some of which are specially adapted to the well-drained soils of the eskers. Additionally, these ridges act as corridors for wildlife, facilitating movement and offering vantage points for species like deer and birds of prey.

Historically, the eskers near Freeville have also had an impact on human activity. Native American communities, recognizing the strategic advantage of these high grounds, are known to have used them as pathways or even settlement sites. In more recent history, the gravel and sand composition of the eskers have made them targets for mining activities. While this has led to the alteration or destruction of some sections, it has also highlighted the importance of preserving these unique geological features for future generations.

Efforts to study and preserve the Malloryville eskers have grown in recent years. Local educational institutions, in collaboration with geological societies, have undertaken detailed studies to understand the formation and significance of these features better. Such initiatives not only contribute to the scientific understanding of glacial processes but also raise awareness about the importance of conserving unique geological formations. Given the potential impacts of climate change on glacial landscapes worldwide, the eskers serve as a poignant reminder of the dynamic nature of our planet and the traces left behind by the ebb and flow of ice ages.

In conclusion, the eskers of Malloryville near Freeville, New York, stand as testaments to the glacial history of the region. These winding ridges, with their intricate patterns and rich ecological contributions, weave a story of natural processes that have spanned millennia. They remind us of the ever-changing nature of our planet and underscore the importance of understanding and preserving its geological wonders. Whether one views them with the eyes of a scientist, historian, or nature enthusiast, the Malloryville eskers offer a captivating glimpse into the ancient forces that have shaped the world around us.

ScienceCenter with Grandchildren

The ScienceCenter museum encourages learning about nanotechnology’s prevalence and unpredictable, unique behaviors.

Our day of science began with measurement: each grandchild’s growth is represented on this corner. Even as young adults they visit and are re-measured. Here Rory is making his mark.

Our science inspired museum, ScienceCenter, is full of fun activities.

Nothing like touching a space object: an iron-nickel meteorite.

So much to learn and discover. Here is Sam perusing a “nano” display.

Nanotechnology is pervasive, existing both in nature and within our technological innovations. Nature offers numerous instances of nanoscale phenomena. For instance, the iridescent hues seen in certain butterflies and the adhesive properties of geckos’ feet are both outcomes of nanostructures.

In our everyday products, nanotechnology plays a significant role. You’ll find it in items you use regularly, such as computer chips featuring minuscule nano-sized components and sunscreen containing nanoparticles. Looking ahead, nanotechnology will play an even more prominent role in our lives.

The question is: Where can you spot the influence of nanotechnology in your own life?

Materials exhibit distinct behaviors at the nanoscale. Tiny particles of gold appear red or purple, as opposed to their conventional shiny, golden appearance. When nanoparticles of iron are dispersed in a liquid, they give rise to a remarkable substance known as ferrofluid, which is a liquid that exhibits a magnetic attraction.

The nanoscale realm also harbors other surprising phenomena. Here, different physical forces dominate, leading to unexpected behaviors. For instance, at nanoscale the force of gravity becomes nearly imperceptible, while static electricity exerts a much greater influence.

Scientists are actively exploring ways to harness these unique nanoscale properties in the development of novel materials and cutting-edge technologies.

Nanotechnology enables us to construct structures much like nature does: atom by atom. Everything in the world is composed of “building blocks” known as atoms. In nature, varied combinations of atoms create diverse materials. For instance, diamond, graphite, and carbon nanotubes are all composed entirely of carbon atoms, but their unique properties emerge from the distinct arrangements of these carbon atoms.

In the field of nanotechnology, we are gaining the knowledge and capability to craft small, functional objects from individual atoms. Remarkably, some new nanomaterials have the capacity to self-assemble, opening up new possibilities for nanotechnology.

Treman Early Autumn Walk XIV

The post discusses the Hepatica acutiloba plant, highlighting its characteristics, growth, historical medicinal use, and its natural habitat in central eastern North America. It also includes an observation made in Robert H. Treman Park.

These characteristic leaves are Hepatica plants growing on the sun dappled southern rim of Robert H. Treman Park captured on a bright late September morning.

“Hepatica acutiloba, the sharp-lobed hepatica, is a herbaceous flowering plant in the buttercup family Ranunculaceae. It is sometimes considered part of the genus Anemone, as Anemone acutiloba, A. hepatica, or A. nobilis. Also generally known as Liverleaf and Liverwort.”


“The word hepatica derives from the Greek ἡπατικός hēpatikós, from ἧπαρ hêpar ‘liver’, because its three-lobed leaf was thought to resemble the human liver.”


“Each clump-forming plant grows 5 to 19 cm (2.0 to 7.5 in) tall, flowering in the early to mid spring. The flowers are greenish-white, white, purple or pinkish in color, with a rounded shape. After flowering the fruits are produced in small, rounded columned heads, on pedicels 1 to 4 mm long. When the fruits, called achenes, are ripe they are ovoid in shape, 3.5–4.7 mm long and 1.3–1.9 mm wide, slightly winged and tend to lack a beak.”

Hepatica Flowers in early spring on the Rim Trail

“Hepatica acutiloba is native to central eastern North America where it can be found growing in deciduous open woods, most often in calcareous soils. Butterflies, moths, bees, flies and beetles are known pollinators. The leaves are basal, leathery, and usually three-lobed, remaining over winter.”

“Hepatica was once used as a medicinal herb. Owing to the doctrine of signatures, the plant was once thought to be an effective treatment for liver disorders. Although poisonous in large doses, the leaves and flowers may be used as an astringent, as a demulcent for slow-healing injuries, and as a diuretic.”

Treman Early Autumn Walk XIII

The Red Pine, Minnesota’s state tree, is a tall, conical, long-lived evergreen with distinctive orange-red bark.

Returning from a Rim Trail walk one April my boots were yellow from a prolific release of pollen from flowers of these tall trees that develop into the woody cones.

Pinus, the pine, is the largest genus in the family Pinaceae, with around 100 species throughout the northern hemisphere.


Red Pine (Pinus resinosa) is Minnesota’s state tree, known there as the Norway Pine. The use of the name “Norway” may stem from early Scandinavian immigrants who likened the American red pines to the Scots pines back home.


“Red pine is a coniferous evergreen tree characterized by tall, straight growth. It usually ranges from 20–35 meters (66–115 feet) in height and 1 m (3 ft 3 in) in trunk diameter, exceptionally reaching 43.77 m (143+1⁄2 ft) tall. The crown is conical, becoming a narrow, rounded dome with age. The bark is thick and gray brown at the base of the tree, but thin, flaky and bright orange red in the upper crown; the tree’s name derives from this distinctive character. Some red color may be seen in the fissures of the bark. The species is self-pruning; there tend not to be dead branches on the trees, and older trees may have very long lengths of branchless trunk below the canopy.”


“It is a long-lived tree, reaching a maximum age of about 500 years. Another member of Pinus, Pinus longaeva D.K. Bailey, the intermountain bristlecone pine, is the longest-lived tree in the world; one in the White Mountains of Nevada is estimated to be 5,000 years old, and by matching rhe rings with even older dead trees, a sequence going back 8,500 years has been established.”

“Red pine is notable for its very constant morphology and low genetic variation throughout its range, suggesting it has been through a near extinction in its recent evolutionary history. A genetic study of nuclear microsatellite polymorphisms among populations distributed throughout its natural range found that red pine populations from Newfoundland are genetically distinct from most mainland populations, consistent with dispersal from different glacial refugia in this highly self-pollinating species.”

Treman Early Autumn Walk XI

Thomas Edison and Henry Ford innovatively used goldenrod to produce rubber, potentially counteracting rubber shortages.

Where the Rim Trail descends to an ending on the Enfield Gorge floor a perennial patch of sunlight promotes an extravagant woodland growth of Zigzag goldenrod.

Solidago flexicaulis, AKA Broadleaf Goldenrod and Ziazag Goldenrod

“Inventor Thomas Edison experimented with goldenrod to produce rubber, which it contains naturally. Edison created a fertilization and cultivation process to maximize the rubber content in each plant. His experiments produced a 12 ft-tall (3.7 m) plant that yielded as much as 12% rubber. The tires on the Model T given to him by his friend Henry Ford were made from goldenrod. Like George Washington Carver, Henry Ford was deeply interested in the regenerative properties of soil and the potential of alternative crops such as peanuts and soybeans to produce plastics, paint, fuel and other products.  Ford had long believed that the world would eventually need a substitute for gasoline and supported the production of ethanol (or grain alcohol) as an alternative fuel. In 1942, he would showcase a car with a lightweight plastic body made from soybeans. Ford and Carver began corresponding via letter in 1934, and their mutual admiration deepened after George Washington Carver made a visit to Michigan in 1937.”

“By the time World War II began, Ford had made repeated journeys to Tuskegee to convince George Washington Carver to come to Dearborn and help him develop a synthetic rubber to help compensate for wartime rubber shortages. Carver arrived on July 19, 1942, and set up a laboratory in an old water works building in Dearborn. He and Ford experimented with different crops, including sweet potatoes and dandelions, eventually devising a way to make the rubber substitute from goldenrod, a plant weed commercially viable. Carver died in January 1943, Ford in April 1947, but the relationship between their two institutions continued to flourish: As recently as the late 1990s, Ford awarded grants of $4 million over two years to the George Washington Carver School at Tuskegee.”

“Extensive process development was conducted during World War II to commercialize goldenrod as a source of rubber. The rubber is only contained in the leaves, not the stems or blooms. Typical rubber content of the leaves is 7%. The resulting rubber is of low molecular weight, resulting in an excessively tacky compound with poor tensile properties.”

Treman Early Autumn Walk X

The zigzag goldenrod is a crucial plant to North American pollinator biodiversity, hosting diverse insects.

After crossing the bridge at Swan Road I turned back down the gorge on the Rim Trail, climbing above the gorge where these interesting woodland goldenrod thrive.

“Solidago flexicaulis, the broadleaved goldenrod, or zigzag goldenrod,is a North American species of herbaceous perennial plants in the family Asteraceae. It is native to the eastern and central parts of the United States and Canada, from Nova Scotia west to Ontario and the Dakotas, and south as far as Alabama and Louisiana. It grows in a variety of habitats including mesic upland forests, well drained floodplain forests, seepage swamp hummocks, and rocky woodlands.”

“The plant is called the “zigzag goldenrod” because the thin, wiry stem zigs and zags back and forth, changing direction at each node (leaf attachment point). The plant bears sometimes as many as 250 small yellow flower heads, some at the end of the stem, others in the axils of the leaves. The leaves are very broad, almost round, but with an elongated tip at the end and large teeth along the edges.”

“Goldenrod is considered a keystone species and has been called the single most important plant for North American pollinator biodiversity. Goldenrod species are used as a food source by the larvae of many Lepidoptera species. As many as 104 species of butterflies and moths use it as a host plant for their larvae, and 42 species of bees are goldenrod specialists, visiting only goldenrod for food. Some lepidopteran larvae bore into plant tissues and form a bulbous tissue mass called a gall around it, upon which the larva then feeds. Various parasitoid wasps find these galls and lay eggs in the larvae, penetrating the bulb with their ovipositors. Woodpeckers are known to peck open the galls and eat the insects in the center.”

“Solidago flexicaulis is host to the following insect induced galls: Asteromyia modesta, a species of gall midges in the family Cecidomyiidae. Gnorimoschema gallaesolidaginis also called the solidago gall moth, goldenrod gall moth or goldenrod gallmaker, is a moth in the family Gelechiidae.”
