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.

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.

History and Ghosts of the Triangle T Ranch

1975 University of Arizona alumnus recounts annual homecoming trips and an encounter with a haunted ranch.

In my Homecoming Parade 2003, I described my initial reconnection with the University of Arizona (U of A) as a 1975 graduate and alumnus.  This personal project of involvement with U of A and Arizona continued through 2011 with annual autumn trips to coincide with Homecoming.  The travel was as a CALS (College of Agriculture and Life Sciences) Alumni Board of Directors member, a primary responsibility was raising funds for scholarships.

I met, Linda Kelly, the owner of the Triangle T Guest Ranch, while camping in the Chiricahua Mountains.  I arrived a week before homecoming to photograph the landscape, nature and rock formations of the Chiricahua National Monument.  Click this link for my Arizona Online gallery, including some work from that time.  Linda and a friend were visiting that day and we struck up a conversation about the area and her Triangle T Guest ranch.  The next day I was scheduled to guest lecture a class at the U of A, as an alumnus of CALS.  The ranch was on the way and I needed a place to stay, so Linda gave me directions and I checked in.

She gave me a tour of the incredible weather granite rock formations of Texas Canyon and, meanwhile, shared stories of the history of Texas Canyon.  It is appropriate for the Amerind Foundation to be here (see first photograph), the winter camp of an Apache tribe for generations.

Weathered granite boulders greet visitors to the Triangle T Ranch.

That night, my request was for a room storied to be haunted by a spirit they call “Grandma,” as in when her footsteps wake you from a sound sleep you say, “It’s all right, Grandmother.”  She woke me that night, footsteps in the dark, hollow on the wood floor, the room filled with a hard cold.  I talked to her, without a response, while swinging my legs out of bed to reach the gas heater in the wall.  I turned on the heat and the sound of expanding metal heat fins lulled me to sleep.

It made a good story for the students.  They were surprised I could fall back asleep, but after all I had to be there the following morning.

I gave Linda a few of my photographs from that day and we made arrangements for the Triangle T to supply a two night package for the CALS “Dean’s Almost World Famous Burrito Breakfast” silent auction during 2008 homecoming.

Newgrange VIII

The Newgrange facade and kerbstones consists of stones from various locations, believed to be transported by sea and river.

The Newgrange façade and entrance of today is a creation from the large quantity of small stones unearthed and conserved during excavation given form by a steel-reinforced concrete retention wall. 

The brilliant white quartz cobblestones were collected from the Wicklow Mountains, 31 miles to the south.  Our guide called them “sunstones” for the way they reflect sunlight. In the following photograph is white quartz, the same excavated 1967-1975 from the Newgrange site and incorporated into the facade, I collected from “Miners Way” along R756 (above Glendalough).

You can also see in these photographs dark rounded granodiorite cobbles from the Mourne Mountains, 31 miles to the north.  Dark gabbro cobbles from the Cooley Mountains and banded siltstone from the shore at Carlingford Lough both locations on the Cooley Peninsula where my mother’s family still has farms.

The stones may have been transported to Newgrange by sea and up the River Boyne by fastening them to the underside of boats at low tide. None of the structural slabs were quarried, for they show signs of having been weathered naturally, so they must have been collected and then transported, largely uphill, to the Newgrange site. The granite basins found inside the chambers also came from the Mournes.

Geological analysis indicates that the thousands of pebbles that make up the cairn, which together would have weighed about 200,000 tons, came from the nearby river terraces of the Boyne. There is a large pond in this area that is believed to be the site quarried for the pebbles by the builders of Newgrange.

Most of the 547 slabs that make up the inner passage, chambers, and the outer kerbstones are greywacke. Some or all of them may have been brought from sites either 3 miles away or from the rocky beach at Clogherhead, County Louth, about 12 miles to the northeast.

Newgrange VII

Approaching Newgrange for the first time

Michael Joseph “Brian” O’Kelly was selected to undertake the direction of the excavation of Newgrange during a 1961 meeting of “those who had a professional interest in the monument” organized by PJ Hartnett, the archaeological officer with Bord Fáilte Eireann (Irish Tourist Board) and a former pupil of Professor O’Kelly’s. Excavation commenced in 1962 and continued every summer for a four-month season up to and including 1975.

The aim of the excavation was to discover as much as possible about the archaeological and historical context of Newgrange and the people who built it and to discover what its original finished appearance was so as to direct a reconstruction, conservation and restoration of the structure to its former condition and appearance.

The last year of excavation was 1975, Michael J. wrote “We determined in 1975 that that should be our last season of excavation at Newgrange. We had investigated approximately one third of the structure and we had discovered much about it that was new, both in its structure and in its ornament, while radiocarbon had pushed its date back by 1,000 years……”

“…We felt that the other two thirds should be left for a future excavator, who, working with new knowledge and perhaps with better methods and new scientific approaches, should have large areas untouched by us in which to test, check and re-evaluate our findings.” From The Restoration of Newgrange by Michael J.O’Kelly. Antiquity LIII, 1979.

“Between the bright sky and the long glittering silver ribbon of the Boyne the land looks black and featureless. Great flocks of starlings are flying across the sky from their nighttime roosts to their daytime feeding places. The effect is very dramatic as the direct light of the sun brightens and casts a glow of light all over the chamber. I can even see parts of the roof and a reflected light shines right back into the back of the end chamber.” The recorded words of Prof O’Kelly spoken in the tomb of Newgrange on the 21st December 1969.

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.”
