Thunderhead Sunset 1

Just the Facts

Cumulonimbus (from Latin cumulus ‘heaped’, and nimbus ‘rainstorm’) is a dense, towering vertical cloud, typically forming from water vapor condensing in the lower troposphere that builds upward carried by powerful buoyant air currents.

Above the lower portions of the cumulonimbus the water vapor becomes ice crystals, such as snow and graupel, the interaction of which can lead to hail and to lightning formation, respectively. When occurring as a thunderstorm these clouds may be referred to as thunderheads. Cumulonimbus can form alone, in clusters, or along squall lines.

Graupel also called soft hail, hominy snow, or snow pellets, is precipitation that forms when supercooled water droplets in air are collected and freeze on falling snowflakes, forming 2–5 mm (0.08–0.20 in) balls of crisp, opaque rime.

Graupel is distinct from hail and ice pellets in both formation and appearance. However, both hail and graupel are common in thunderstorms with cumulonimbus clouds, though graupel also falls in winter storms, and at higher elevations as well.

These clouds can produce lightning and other dangerous severe weather, such as tornadoes, hazardous winds, and large hailstones. Cumulonimbus progresses from overdeveloped cumulus congestus clouds and may further develop as part of a supercell. Cumulonimbus is abbreviated Cb.

A large and varied genus

“Water Banana”

Pam and I ambled around the Arboretum for our Easter 2023 outing. We discovered this seeming lily growing from the muck along the Treman Woodland Walk. Scientific Name: Lysichiton camtschatcensis. Common names: Asian skunk cabbage, white skunk cabbage, Far Eastern swamp lantern or Japanese swamp lantern.

This is a plant found in swamps and wet woods, along streams and in other wet areas of the Kamchatka Peninsula, the Kuril Islands, Sakhalin and northern Japan. The common name “skunk cabbage” is used for the genus Lysichiton, which includes Lysichiton americanus, the western skunk cabbage, noted for its unpleasant smell. The Asian skunk cabbage is more variable: plants have been reported in different cases to smell disgusting, not at all, and sweet.

In Japanese it is known as mizubashō (lit. “water-banana”) from a supposed similarity to the Japanese banana, a name with poetic rather than malodorous associations. It is not closely related to the true cabbage.

Stone Bench Memorial

Old Testament

Pam and I ambled around the Arboretum for our Easter 2023 outing. We found a path new to us, with this memorial stone bench, a biblical quote engraved on the seats. Biblical Quote on bench: “What doth the lord require of thee / but to do justly and to love mercy / and to walk with thy god.” Micah 6:8

The Book of Micah is the sixth of the twelve minor prophets in the Hebrew Bible. Ostensibly, it records the sayings of Micah, whose name is Mikayahu (Hebrew: מִיכָיָ֫הוּ), meaning “Who is like Yahweh?”, an 8th-century BCE prophet from the village of Moresheth in Judah (Hebrew name from the opening verse: מיכה המרשתי). The book has three major divisions, chapters 1–2, 3–5 and 6–7, each introduced by the word “Hear,” with a pattern of alternating announcements of doom and expressions of hope within each division. Micah reproaches unjust leaders, defends the rights of the poor against the rich and powerful;[ while looking forward to a world at peace centered on Zion under the leadership of a new Davidic monarch. While the book is relatively short, it includes lament (1.8–16; 7.8–10), theophany (1.3–4), hymnic prayer of petition and confidence (7.14–20), and the “covenant lawsuit” (6.1–8), a distinct genre in which Yahweh (God) sues Israel for breach of contract of the Mosaic covenant.

In the quote tract, (6:6–8), Micah speaks on behalf of the community asking what they should do in order to get back on God’s good side. Micah then responds by saying that God requires only “to do justice, and to love mercy, and to walk humbly with your God.” Thus declaring that the burnt offering of both animals and humans (which may have been practiced in Judah under Kings Ahaz and Manasseh) is not necessary for God.

A Personable Tree

Gifts from the past

Pam and I ambled around the Arboretum for our Easter 2023 outing. Found here growing outside native range, being the Appalachian Mountains from Georgia to southern Pennsylvania, the Table Mountain Pine is named after the landform, not a particular mountain.

Click Me for “Finger Lakes Memories” my online gallery.

Its pinecones drew me to this scraggly, ungainly, poorly formed tree. All general mankind finds useful in the, scientific name, Pinus pungens, otherwise known as Hickory Pine, Prickly Pine and Mountain Pine, is to grind it up for pulp or chop it for tinder.

Last of the Mohicans

That said, the final scene of the 1992 film The Last of the Mohicans takes place in a nice Pinus pungens stand on a rocky mountaintop in North Carolina.

Personality

The tree has personality. Pinus pungens is the Lonesome Pine of the 1908 novel The Trail of the Lonesome Pine by John Fox, and popularized in the Laurel and Hardy film Way out West: “On the Blue Ridge Mountains of Virginia On the Trail of the Lonesome Pine” Several “Lonesome Pine” hiking trails have been waymarked in the Blue Ridge Mountains and elsewhere in the Appalachians.

Pinecone Bud

Pinus pungens prefers dry conditions and is mostly found on rocky slopes, favoring higher elevations, from 300–1,760 meters (980–5,770 ft) altitude. It commonly grows as single scattered trees or small groves, not in large forests like most other pines, and needs periodic disturbances for seedling establishment. The three tallest known ones are in Paris Mountain State Park, South Carolina; they are 26.85 to 29.96 meters (88 ft 1 in to 98 ft 4 in) tall.

Bluestone Monuments

Gifts from the past

Pam and I ambled around the Arboretum for our Easter 2023 outing. A type of sandstone popular with Cornell monument builders, called “Lenroc” after a mansion build by Cornell’s founder, was used for these benches built into the hillside of the FR Newman Arboretum. The views are more interesting than the bench, the arch of stone in midground in one photo.

The stone is mined locally from surrounding hills. Calling it “Lenroc” (Cornell spelled backward) is a misnomer as the stone is mined widely throughout the region.

Feldspathic Greywacke

“Bluestone from Pennsylvania and New York is a sandstone defined as feldspathic greywacke. The sand-sized grains from which bluestone is constituted were deposited in the Catskill Delta during the Middle to Upper Devonian Period of the Paleozoic Era, approximately 370 to 345 million years ago…..

Glacial Landscape on an early spring day, Easter 2023

Textures

…The Catskill Delta was created from runoff from the Acadian Mountains (“Ancestral Appalachians”). This delta ran in a narrow band from southwest to northeast and today provides the bluestone quarried from the Catskill Mountains and Northeastern Pennsylvania. The term “bluestone” is derived from a deep-blue-colored sandstone first found in Ulster County, New York.”

You can feel the origin of this bluestone from these macros of two pavers from a monument bench.

Golden Gift

White on White

We mistook this magnolia tree for a “pussy willow” from its flower bud texture and shape.

The signage attached to a branch disabused us of this impression, incorrect all for being true until the flowers burst forth.

Magnolia “Golden Gift” Magnoliaceae

Description

A visually beautiful magnolia whose golden flowers bloom in abundance and persist well; a small tree or large shrub with a loosely pyramidal form and large relatively coarse leaves; flowers appear before the foliage; an ideal landscape or garden accent

Ornamental Features

Golden Gift Magnolia is covered in stunning fragrant gold cup-shaped flowers held atop the branches in early spring before the leaves. It has dark green deciduous foliage. The large pointy leaves turn coppery bronze in fall.

Landscape Attributes

Golden Gift Magnolia is a deciduous tree with a distinctive and refined pyramidal form. Its relatively coarse texture can be used to stand it apart from other landscape plants with finer foliage. This is a relatively low maintenance tree and should only be pruned after flowering to avoid removing any of the current season’s flowers. It has no significant negative characteristics.

Ancient

Magnolia is an ancient genus. Appearing before bees evolved, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and fossils of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea (as well as with many more recently derived plants such as Lilium).

Jack Pine

New York Native

Pam and I ambled around the Arboretum for our Easter 2023 outing. Ezra Cornell had a large farm on the East Hill above Ithaca, New York. As part of locating New York State’s land-grant college in Ithaca, Cornell offered to donate the farm for use as a campus. Parts of this property remain in use as farmland. Our walk followed the outer Arboretum reaches along this research farm.

Growing off the road that loops around the Arboretum, this scraggly pine, the Jack Pine, attracted our attention by the grey colored growths curving around the branches 

Serotinous

These are pinecones with the unusual property of not opening, hanging onto the branch, turning this color, until the appropriate conditions arise, serotinous is the botanic term for this. They open when exposed to intense heat, greater than or equal to 50 °C (122 °F). The typical case is in a fire, however cones on the lower branches can open when temperatures reach 27 °C (81 °F) due to the heat being reflected off the ground. 

The Color of Younger Jack Pine Cones

Form and Behavior

Tolerant of conditions that preclude other trees, Jack Pines can form pure stands on sandy or rocky soil. It is fire-adapted to stand-replacing fires, with the cones remaining closed for many years, until a forest fire kills the mature trees and opens the cones, reseeding the burnt ground.

Native

Pinus Banksiana, Pinaceae, Jack Pine, Nova scotia to New York and Minnesota

Joseph Banks classified this pine during a 1766 expedition to Labrador and Newfoundland, the scientific name, Pinus Banksiana, is in his honor.  Jack Pine is native to eastern North America in the far north, south to northwestern Pennsylvania, including New York State.

Long Island Sakura (Cherry Blossoms)

Clouds of Blossoms

A Japanese flowering cherry tree in bloom on an early May day. Called a Shirofugen (Secientific name: Prunue serrulata, of the Rosaceae family this is the species planted around National Tidal Basin, Washington D.C. and around which the National Cherry Blossom Festival is celebrated commemorating the 1912 gift of Prunus serrulata Japanese cherry trees from Tokyo to the city of Washington.

The tree over Pam is called a Shirofugen (Scientific name: Prunus serrulata, of the Rosaceae family) and is one species planted around National Tidal Basin, Washington D.C. Shirofugen blossoms are described “Flowers double, deep pink at first, fading to pale pink.”

In Japan, since the 8th century, “Hanami” is the centuries-old practice of picnicking under a blooming sakura or ume tree. Here in the United States, the National Cherry Blossom Festival is celebrated commemorating the 1912 gift of Prunus serrulata Japanese cherry trees from Tokyo to the city of Washington.

Traditionally cherry blossoms remind the Japanese of clouds, the blooms come out en mass, the tree changes shape with the breeze.  Viewing sakura brings to mind thoughts of the transience of existence, the fragility and transience of the exquisite blooms leads one to appreciate the moment.  The following photograph of Pam was taken a month before my Mother’s sudden decline and passing in 2013.  We’d travel to Long Island several times a year to visit her, then take in familiar sights.

Growing up, our family visited the Planting Fields, a state park, several times in the spring and summer. As an adult with a growing family in Glen Cove, right around the corner, the Planting Fields were a welcome outing and visited several time times a year. The following photograph, taken that same May 2013 day, was a favorite park scene.

The two flowering cherry trees in the foreground are a type of Japanese sakura called Yoshino, one the most popular flowering cherries in temperate climates worldwide. All Yoshinos are clones from a single grafting and propagated throughout the world. The scientific name outlines the cross breeding of this variety, Prunus X Yeaoensis. Behind the cherries is an Oak tree, new leaves a bright green, and a pink child’s playhouse cottage.

A changing scene of the park is the now frequent visits by wedding parties and photographers, groups of Asian people, the bride and groom posing under the clouds of blossoms. By frequent I mean a steady stream, one after the other, when the blossoms are full.

In 2007 I spent hours framing and capturing the following photograph on a Saturday, the day before Mother’s Day, during a visit to my Mother, who was widowed December, 1995. I used an inexpensive tripod, a Kodak DCS Pro slr/c camera body with the Canon 50mm f 1.4 USM lens, a UV filter and lots of time. There were no interruptions that day, at 5:30 pm I had the area to myself.

This child’s garden playhouse, framed by an ancient oak, pink Japanese cherry blossoms and gracious lawn was awarded a Photographic Society of American, Pictorial Print Division, Print of the Month award, published in the society magazine for that month.

A Visit to Salado Ruins

Happy April First “this post is no joke”

About 700 years ago, when the expansion of the Mongol empire was under way, on the other side of the planet people discovered a series of caves, formed in tuff, with a favorable location in a south facing cliff near water.  Tuff, a rock formed from volcanic ash, is hard, brittle and soluble in water.  From these properties this series of caves formed.  The southern exposure provided excellent climate control for people, like those we now call the Salado, who understood how to exploit the location.

They constructed from local materials (mud, plants and rock) rooms in the upper cave just far enough inside to be warmed by the winter sun and protected during the summer when the sun’s sky-path was higher.  Who knows how long the Salado lived in what must have been this paradise or why they left.

Rogers Canyon

In March 2006, after returning from a nine-day backpack trip to the remote eastern Superstition Wilderness I used a four-wheel vehicle to reach the Roger’s Trough trailhead for a day trip to this site in Roger’s Canyon.  The advantage of Roger’s Trough is the high elevation that leaves “just” about 1,100 feet of climbing (2,200 total) for the day.  As it happens, it is downhill to the ruins though there is plenty of ups and downs plus scrambling over rocks.

I started late morning and a returning party met me on the way out and warned against leaving packs unattended.  It seems they were victimized by pack rats.  My timing was lucky and I had the site to myself.

First (refer to the “Roger Canyon” photograph,  above) I climbed the cliff opposite from the ruins to set up a tripod an telephoto lens to shoot through the trees to capture the main building inside that very interesting looking tuff (see below).  That central column (to the right) divides the cave opening and there are views from inside, up and across the canyon.  In season, the cliffs are occupied by nesting birds and, higher up, there are fascinating caves in locations too high and steep to reach without the proper equipment.

As it is, climbing into the upper cave requires an exposed rock scramble.  By “exposed” I mean the climber is exposed to falling.  That is an intact wooden lintel of the visible structure opening and the larger structure, to the right, has curved walls.

Salado Cave Ruin

I then explored in and around the site.  The location of a lower cave made it useful for storage, it was walled off and the sturdy structure still stands today.  By the way, I inverted this view for artistic purposes.

Lower Storage Room

A lower cave is opened and accessible.  Looking out, I felt the original inhabitants were with me and then a raven started calling over and over and over.

Lower Cave

I was so fascinated by the possibilities of the site that time got away from me until this incessant cawing of a raven made me notice the lengthening cliff shadows.  Here is a view (see below) of my way home, back up Rogers Canyon.  My last shot before packing up.  It took just over two hours to get out, at a steady pace.  It was twilight as I approached the Rogers Trough trail head.

By the way, my posting before this one (“Finding Circlestone”) includes a shot of White Mountain.  In that view, these ruins are on the other side of White Mountain.

Cochise Stronghold and Moon

at dawn

Interstate 10 between Benson and Wilcox ascends through a field of enormous, eroded granite boulders. Off to the west are the Dragoon Mountains, otherwise known as “Cochise Stronghold.” This rugged area served as a natural fortress and hideout for Apache Indians of the Chiricahua clan led by Cochise. He was born in this Dragoon Mountains about 1815. From 1869 to 1872 the Cochise band battled the U.S. Calvary because of the handling of an incident at Apache Pass about 30 miles east of here. It is believed that Cochise was buried somewhere in the Stronghold.
