Cape Henry Lighthouse: Lit 1792 on Chesapeake Bay as First US Lighthouse


Summary: Cape Henry Lighthouse is U.S.'s first lighthouse and first publish works project as a new nation. Lit from 1792 to 1881, it still stands on Chesapeake Bay.

Cape Henry marks the southern side of the entrance to the Chesapeake Bay, a large, Atlantic Ocean estuary on the North American coast. Cape Charles defines the northern side of the entrance to the partly enclosed, inland body of brackish water.
Known as the Virginia Capes, the two headlands were named for the two sons of James I (June 19, 1566–March 27, 1625), King of England and Ireland (March 24, 1603–March 27, 1625) during the North American expeditions of the Virginia Company (April 10, 1606–May 24, 1624).
Cape Henry honors elder son Henry Frederick, Prince of Wales (Feb. 19, 1594–Nov. 6, 1612).
Cape Charles honors younger son Charles (Nov. 19, 1600–Jan. 30, 1649), Duke of Albany and, later, King Charles I of England and Ireland (March 27, 1625–Jan. 30, 1649).
The Cape Henry Lighthouse holds the honor of being the first lighthouse built under the authority of the newly formed nation of the United States of America.
The Act for the Establishment and Support of Lighthouses, Beacons, Buoys, and Public Piers was approved Friday, Aug. 7, 1789, as the ninth piece of official legislation passed by the First United States Congress, which met from March 4, 1789, to March 4, 1791.
The Act has landmark status as the first public works act passed by Congress. Included in the Act is specific mention of the construction of the Cape Henry Lighthouse:
“Sec. 2. And be further enacted, That a lighthouse shall be erected near the entrance of the Chesapeake Bay, at such place, when ceded to the United States in manner aforesaid, as the President of the United States shall direct.” (Chapter IX)
By November 1789, the Virginia General Assembly ceded land at the tip of Cape Henry in Princess Anne County (now the independent city of Virginia Beach). The site stands less than one-quarter of a mile (0.32 kilometers) from the First Landing, the point where Captain Christopher Newport (Dec. 29, 1561–Aug. 15, 1617) and Virginia Company colonists landed April 26, 1607. The landing preceded establishing England’s first permanent American settlement on May 4, 1607, at Jamestowne, to the north on the James River, Virginia’s largest Chesapeake Bay tributary.
Secretary of the Treasury Alexander Hamilton (Jan. 11, 1755/1757–July 12, 1804) selected New York City architect John McComb Jr. (1763–1853) as designer for the new nation’s first lighthouse.
McComb’s final plans included revised foundation depth from 13 feet (3.96 meters) to 20 feet (6.09 meters) below sea level as well as increased base diameter from 27 feet 6 inches (8.38 meters) to 33 feet (10.05 meters).
With a thickness of 11 feet (3.35 meters), the exterior wall presents a circular design for the first 4 feet (1.2 meters), then rising for 93 feet (28.3 meters) as an octagonal truncated pyramid to the 13-foot (3.96 meters), fish oil-fueled lantern tower.
Building materials, for which the architect was responsible contractually, utilized Aquia sandstone that had been brought over from Brooks Quarry on the Rappahannock River for an earlier, failed attempted at lighthouse construction by the royal colonies of Maryland and Virginia.
Final cost of $17,700 ($425,000-plus in 2015) ran $2,500 ($60,000-plus in 2015) over the project’s first estimate.
Cape Henry Lighthouse was first lit in October 1792 by its third keeper, Laban Goffigan. The first keeper, William Lewis, died within a month of his appointment. The second keeper, Lemuel Cornick, abandoned his post after less than a year.
Subsequent renovation projects included lantern improvements in 1841 and repairs by 1863 from Confederate damage during the War Between the States (April 12, 1861–April 9, 1865). The original wooden access was replaced with a cast iron staircase in 1867.
Cape Henry Lighthouse was last lit Dec. 15, 1881, by its last keeper, photographer Jay Dearborn Edwards (1831-1900), who then lit the new, adjacent Cape Henry Lighthouse as its first keeper. Large cracks in six of the old lighthouse's eight faces, detected during a routine inspection in 1872, had necessitated construction of a replacement 350 feet (106.68 meters) to the southeast.
In 1914, the lighthouses were encompassed within military land with the installation of Fort Story, which became Joint Expeditionary Base (JEB) Little Creek-Fort Story via transfer Oct. 1, 2009, to the United States Navy.
On June 18, 1930, Congress deeded the original lighthouse and 1.77 acres to Preservation Virginia.
The lighthouse's significance is recognized through enlistment as: National Historic Landmark in 1972; National Register of Historic Places on Oct. 15, 1966; and Virginia Landmarks Register on Sept. 9, 1969.
The old lighthouse visibly stands sentinel with its cast iron replacement.
Under Preservation Virginia’s ownership, Cape Henry Lighthouse is open to the public. With entrance to the historic lighthouse by way of JEB security gates, valid identification is required.
Exuding the sweep of history of a young nation and offering vibrant panoramas, Old Cape Henry Lighthouse is a must-see landmark, especially for history, lighthouse and maritime enthusiasts.

Meditation by the Sea: Splendid 1860s Folk Art by Unknown Artist


Summary: Meditation by the Sea, an 1860s painting in folk art/Hudson River School styles by an unknown artist, is on view in Boston's Museum of Fine Arts.

Meditation by the Sea is an oil on canvas painting created by an unknown artist in the 1860s.
The painting’s dimensions measure a height of 13 5/8 inches (34.61 centimeters) and a width of 19 5/8 inches (49.85 centimeters). Meditation by the Sea presents a solitary figure, clothed in black, standing amid a clutter of tidal debris and thoughtfully pondering white-crested waves breaking nearby on the shore.
The unknown artist displayed influences of the Hudson River School, which flourished from around 1850 to 1900 as an artistic fraternity of landscape painters originally based in New York City. Credit for founding the mid-19th century art movement generally is bestowed upon English émigré artist Thomas Cole (Feb. 1, 1801–Feb. 11, 1848), whose interest in landscapes motivated his settling in New York City in 1825. The Hudson River School’s second generation of artists refined vistas of nature’s grandeur and sublime beauty through the light-in-the-landscape technique and style of Luminism, especially exemplified by Frederic Edwin Church (May 4, 1826–April 7, 1900) and Nathaniel Rogers “Fitz Henry” Lane (Dec. 19, 1804–Aug. 14, 1865).
The unknown artist styled Meditation by the Sea with elements of folk art, the untrained, usually colorful artistry of everyday people. Naïve depictions of perspective and proportion starkly heighten the aesthetic impact of the marine landscape.
An inspiration for Meditation by the Sea has been sourced to Gay Head, a wood engraving by magazine illustrator and writer David Hunter Strother (Sept. 26, 1816–March 8, 1888) under his pseudonym of Porte Crayon (French: porte-crayon, “pencil/crayon holder”).
Gay Head appeared in Porte Crayon’s article, “A Summer in New England,” published Sept. 21, 1860, Harper’s New Monthly Magazine. Porte Crayon’s article described the ocean as invoking awe with unceasing rolling since “the Spirit of God moved upon the face of the waters” (Genesis 1:2) and conveying the waters’ “tumultuous spirit” during a leisurely stroll amidst the beach’s tide-strewn curiosities.
Provenance, or record of ownership, traces to the New York gallery of German émigré art dealer Israel Ber “J.B.” Neumann (March 2, 1887–April 28, 1961) as a purchase in 1943 by Russian émigré tenor opera singer and art collector Maxim Karolik (1893–Dec. 20, 1963).
On Dec. 13, 1945, Maxim Karolik gifted Meditation by the Sea to the Museum of Fine Arts (MFA) in Boston, Massachusetts. Museum visitors may view Meditation by the Sea in the Joyce and Edward Linde Gallery (Gallery 237).
Viewing Meditation by the Sea face-to-face numbers among the multitude of high points enjoyed during a visit to Massachusett’s historic capital by the sea.
The luminous painting provides an unforgettable vista for sea admirers as well as for enthusiasts of folk art and of sea paintings.

Aug. 29 Supermoon Kicks Off Three Months of Supersized Full Moons


Summary: The Aug. 29 supermoon kicks off three months of supersized full moons as 2015's first supermoon; Great Lakes tribes know it as the sturgeon moon.

A sextet of waxing gibbous moons, shining nightly with increasing brightness amid clear skies, yields to a full supermoon Saturday, Aug. 29, 2015. The waxing gibbous phase represents 51 to 99 percent illumination of the lunar disc, as viewable to Earthlings.
August 2015 celebrates the month’s last waxing gibbous moon, occurring Friday the 28th, in a crescendo of brightness, with a 98 percent-lit disc.
As the fourth phase of the monthly eight-phase lunar cycle, a full moon forms a straight line, known as syzygy (Ancient Greek: σύζυγος, suzugos, “yoked together”), with the Earth and the moon. The full moon is positioned on the opposite side of the Earth from the sun.
The opposite of full moon syzygy in positioning between Earth and sun, new moon syzygy complements full moon syzygy.
In the moon’s monthly elliptical orbit around the Earth, perigee designates the closest distance, as measured center-to-center in the two celestial bodies. Perigee is a variable figure, with proxigee representing the year’s closest perigee.
A center-to-center distance of less than 224,834 miles (361,836 kilometers) yields the moniker of supermoon in recognition of the proximity-induced optical illusion of an unusually large moon. August's perigee cozies up to Earth at a center-to-center distance of 222,631 miles (358,290 kilometers). August's perigee actually takes place Sunday the 30th at 15:24 Coordinated Universal Time (11:24 a.m. Eastern Daylight Time).
Saturday the 29th's moon crests at fullness at 18:35 UTC (2:35 p.m. EDT; 7:35 p.m. British Summer Time). With perigee in only 21 hours 11 minutes, August's full moon qualifies as a full supermoon.
Native American tribes tracked the seasons by naming monthly full moons according to events in nature.
Tribes of the Great Lakes identified August's full moon as sturgeon moon in acknowledgment of ease of catching plentiful sturgeon (family Acipenseridae) at this time.
Green corn moon, another epithet, marked the impending harvest of September's full corn moon.
The Dakotah Sioux and the Ojibway knew August's full moon as "moon when all things ripen" and blueberry moon, respectively.
August’s full supermoon passes the torch for bigness and closeness to its successor, September’s full supermoon. Occurring Monday the 28th, September’s supersized moon zooms to a center-to-center closeness of 221,753 miles (356,877 kilometers).
August's full supermoon shines brilliantly, even through cloudy veils, during its east-to-west transit across Earth's night sky.
To paraphrase "That's Amore," the 1952 Oscar-nominated song by composer Harry Warren (Dec. 24, 1893–Sept. 22, 1981) and lyricist Jack Brooks (Feb. 14, 1912–Nov. 8, 1971):
"When the Moon hits your eye like a big sturgeon pie, that's August's Moon."

Red Spotted Purple Butterfly: Blue Black Beauty of Limenitis astyanax


Summary: Native to central/eastern U.S., Red Spotted Purple Butterfly (Limenitis arthemis astyanax) mimics Pipevine Swallowtail's black and iridescent blue colors.


Red Spotted Purple in Bloomington, southwestern Indiana: Saxophlute, CC BY SA 3.0 Unported, via Wikimedia Commons

Limenitis arthemis astyanax is a New World butterfly native to southeastern Canada and central and eastern United States.
In Canada, Limenitis arthemis astyanax is native to southern Ontario, stretching from Georgian Bay into the southwestern peninsula.
In the United States, homelands range from southern New Hampshire southward to central Florida and westward through the eastern stretches of the eastern Great Plains states from North Dakota through Texas.
The trio of scientific names for Limenitis arthemis astyanax reflects the butterfly’s status as one of four subspecies within the arthemis species.
Limenitis arthemis astyanax is known commonly in English as Red Spotted Admiral or as Red Spotted Purple. The common name of admiral reflects its membership in the Limenitis genus, known commonly as the admirals.
Associated with forests, Red Spotted Purple Butterfly favors deciduous wooded habitats such as forest edges and openings as well as at roadsides and along woodland trails. Red Spotted Purple also may be found along small hills and on hilltops.
As mud puddlers, Red Spotted Purple Butterflies seek damp microenvironments such as gravel paths and roads in order to extract moisture and nutrients.
As a large butterfly, Red Spotted Purple measures wingspans of almost 4 inches (100 millimeters).
Forewings are long and rounded. Hindwings display scalloped edges.
Dorsal, or upperside, wing colors feature black forewings and iridescent blue hindwings. Orange oblong rows framing forewing blackness contrast vividly with iridescent blue margins. Curved white dash marks edge all wing margins.
Ventral, or underside, wing colors present dull brown or black backgrounds. Undersides are brightened with orange spots spraying basally from near thorax. They are framed with prominent orange band. Ventral wings are edged with two rows of iridescent blue, curved dashes.
Red Spotted Purple Butterfly eludes predators through mimicry. Minus the distinctive swallowtail, Red Spotted Purple Butterfly resembles the black-and-blue themed Pipevine Swallowtail (Battus philenor), which repels predators via a foul-tasting reputation.
As a member of the global Nymphalidae family, known commonly as brush-footed butterflies, the Red Spotted Purple may hold its wings flat open while resting. While mud puddling, the Red Spotted Purple rhythmically opens and closes their wings -- thereby giving spectacular views of undersides and uppersides -- possibly in mimicry of Pipevine Swallowtail's noticeable fluttering during nectaring.
Favorite host plants Limenitis arthemis astyanax larvae include Wild Cherry Tree (Prunus serotina), Deerberry Shrub (Vaccinius staminiun) and Carolina Willow Tree (Salix caroliniana).
Nectar sources favored by Limenitis astyanax include carrion, overripe to rotten fruit and tree sap.

Last week a Red Spotted Purple leisurely cruised past my east living room window, which looks over the front porch. Augusta "Gusty" Sunshine, my Maine Coon black-and-white kittycat, followed me to the door, where I beheld the gorgeous butterfly resting on a damp spot on the porch's concrete floor.
The Red Spotted Purple only relocated half a dozen times to different, accessible areas of the porch after I slowly ventured outside. Lying down flat, inching like a worm, with Gusty alongside me, I was able to take closeups with my cellphone camera. Oftentimes my outstretched hand rested at a closeness of less than 6 inches (15.24 centimeters) from the unfazed butterfly.
After about 15 minutes, the Red Spotted Purple soared up from the porch floor, tracing a graceful arch toward the southern column and beyond toward the rugged Virginia Red Cedar Tree (Juniperus virginiana). The Red Spotted Purple then disappeared amid the towering American Pokeweeds (Phytolacca americana), blackberry brambles (Rubus fruticosus) and Yellow Crownbeards (Verbesina occidentalis) of the southwestern meadow.

Striped Skunk: North American Nocturnal Roamings of Mephitis mephitis


Summary: Striped Skunk (Mephitis mephitis) is a New World skunk familiar as nocturnal roamer throughout North American homelands (Canada south to northern Mexico).


Striped Skunk, with arched back and raised tail as warning to potential foes: Wisconsin Department of Natural Resources, CC BY ND 2.0 Generic, via Flickr

Mephitis mephitis is a New World skunk native to North America from northern Mexico to southern mainland Canada.
In Canada, homelands stretch from coast-to-coast in all provinces except for Prince Edward Island and Newfoundland and Labrador as well as in southern Northwest Territories and Yukon Territory.
In the United States, Mephitis mephitis ranges throughout the entire Lower 48.
In Mexico, Mephitis mephitis is native to all seven northern states: Chihuahua, Coahuila, Durango, Nuevo León, Sinaloa, Sonora, Tamaulipas.
Mephitis mephitis is known commonly in English as Striped Skunk.
The Striped Skunk features a jet black, stout body marked with two long white stripes, one on each side, that join at the nape and flare into a cap atop the small head. A narrow white stripe extends from the forehead down to the nose. The bushy black tail often is interspersed with white strands or tipped with white.
The Striped Skunk’s mature size matches that of a domestic cat. With males slightly larger than females, adults average lengths, from nose to tail, ranging from 22 inches to 31 inches (55.8 to 78.74 centimeters). The tail may contribute almost 50 percent to the total body length.
Short legs account for the Striped Skunk’s slow, waddling gait. As a plantigrade (Latin: planta, "sole of the foot" + gradus, "step") mammal, the Striped Skunk touches the ground with full soles of feet.
Five partially webbed toes are endowed with long, non-retractable claws, which are longer and curved, for digging, on front feet and shorter and straighter on hind feet. Striped Skunk tracks average 2 inches (5.08 centimeters) in length by 1 inch (2.54 centimeters) in width.
When feeling threatened, an adult Striped Skunk may release from grape-size anal scent glands a pungent fluid, either as a fine spray or as a stream. The excretion has a reach from 10 to over 18 feet (3.048 to 5.48 meters).
Amounting to about one tablespoon in each gland, the oil-based, yellow musk lasts for five to eight firings. With about a week required for replenishing glands, the Striped Skunk exhibits thrift in dispensing the limited supply.
The Striped Skunk has an average lifespan of three years in the wild. A Striped Skunk's lifespan averages 10 to 15 years in captivity.
Striped Skunk displays habitat versatility in rural, suburban and urban environments.
As an opportunistic omnivore with a partiality for insects such as beetles (order Coleoptera) and grasshoppers (suborder Caelifera), the Striped Skunk values locations with abundant supplies of food and cover.
As a crepuscular and nocturnal mammal, the Striped Skunk especially enjoys roaming in open areas and forest edges at twilight and during the night.
The threat of being sprayed by the Striped Skunk’s foul scent dissuades many predators. Emboldened by a poor sense of smell, however, the Great Horned Owl (Bubo virginianus) engages in serious predation of Striped Skunks.

One evening before my black-and-white Maine Coon cat, Augusta "Gusty" Sunshine, transitioned from stray to house cat, I heard her mew from the north retaining wall in my front yard.
Looking out, I observed Gusty, her black-splotched white coat gleaming in the moonlight, leaning down from her perch to touch noses with two Striped Skunks -- their coats a study in opposites to Gusty's -- who were craning to reach her from the ground.
Always generous as a stray with her food, she inched backward to allow her sociable guests to share in her bedtime snack.

Cherax snowden sp. n. (species nova) is a newly named species native to the Indonesian province of West Papua in northwestern New Guinea. The large South West Pacific island is equally divided between the Republic of Indonesia and the Independent State of Papua New Guinea.
The brightly colored crayfish claims Sawiat District’s Oinsok River Drainage in South Sorong Regency (Sorong Selatan) of central Kepala Burung (Dutch: Vogelkop; English: Bird’s Head) Peninsula as specific homeland.
Cherax snowden was misidentified with another West Papuan crayfish, Cherax holthuisi, described by crayfish researchers Christian Lukhaup and Reinhard Pekny in 2006. Discovery of different homelands -- with Cherax holthuisi only found in the wild in South Sorong Regency’s Kais River Drainage -- and detection of additional differences in coloring, DNA, shape of rostrum (protective spike beyond eyes) and pincers (chelae) necessitated establishing a new species.
The addition of Cherax snowden increases to 56 the number of species within Cherax, the Southern Hemisphere's largest and most widely distributed, fully aquatic crayfish genus.
As an admirer of former U.S. NSA (National Security Agency) contractor Edward Snowden (born June 21, 1983), Christian Lukhaup, researcher at Berlin’s Humbold University, presented the new species name on Aug. 24, 2015, in a research article co-authored with Jörn Panteleit and Anne Schrimpf of University Koblenz-Landau and published online by ZooKeys.
The German researcher analogizes the new species to the “American freedom fighter” accordingly: with an extremely hard protective shell and tiny but effective pincers, a powerful species that evades enemies by hiding under rocks and emerging at night.
Because of their vivid coloration, Christian Lukhaup has ornamented Cherax snowden with the common names of Green Orange Tip and Orange Tip. Cherax snowden also is known as snowden crayfish.
Apparently endemic to tributary creeks of the Oinsok River, Cherax snowden lives in clear, shallow water characteristically devoid of water plants. Rocky creek beds are covered with rocks, silt and stones.

The brightly ornamented freshwater crayfish reaches lengths of 2.7 to 3.97 inches (69 to 101 millimeters) in male specimens. Measurement of a female yielded a length of 3.03 inches (77 millimeters).
Coloring primarily emphasizes green and orange. Pincers (chelae) are green-themed, varying from light to dark or green grey, and end with dramatic orange tips. The cephalothorax presents a range of green, from light to dark to bluish or brown. The abdomen, which mirrors the upper body’s coloring, also features transverse orange bands. Walking legs vary from dark green to blue grey or creamy to brownish yellow. The tail-fan has a cream-to-orange margin.
Collected in large numbers, Cherax snowden is popular as an ornamental for the global aquarium trade and as a food source for local West Papuans.
Cherax snowden’s describers express concern over decreasing numbers noted by collectors. They suggest the need for improved knowledge through further research as well as the necessity of possible conservation management plans, including a captive breeding program.

Moon Fire Fountains: Carbon Triggered Lava Blasts of Volatile Moon


Summary: Volcanic glass beads reveal ancient lunar volatility as carbon triggered lava blasts, according to a letter published Aug. 24 in Nature Geoscience.

The ancient scenario unfolding for the moon, the Earth’s only natural satellite, features persistent volatility reminiscent of such fire fountains as eruptions from Hawaii’s Puu Oo and southwestern Iceland’s Eyjafjallajökull volcanoes.
Current research hypothesizes a collision in the early solar system between Early Earth and Theia, a Mars-size planet, as the source of debris for the moon’s formation. The collision presumably occurred around 4.533 billion years ago (BYa) during Early Earth, the first billion years of the Blue Planet’s existence.
As the early moon coalesced from spewed debris, carbon-steeped magma (Ancient Greek: μάγμα, mágma, “ointment, thick unguent”) combined with oxygen to form carbon monoxide during its rise from lunar depths. With decreasing pressure near the lunar surface, lava laced with carbon monoxide bubbles exploded above ground as fiery fountains.
Volcanic glass, formed from droplets of molten lava on the lunar surface, often preserves gases by way of melt inclusions, tiny dots of magma in crystal enclosures. Super-sensitivity of the NanoSIMS (Secondary Ion Mass Spectrometry) ion probe, manufactured by France-based SIMS superstar CAMECA (Compagnie des Applications Mécaniques et Électroniques au Cinéma et à l’Atomistique), enabled a breakthrough discovery in understanding lunar volcanic glass at Washington D.C.’s Carnegie Institution for Science by Erik H. Hauri, a geochemist at the private institution, in collaboration with a research trio of Brown University professors: Diane T. Wetzel, Alberto E. Saal, and Malcolm J. Rutherford.
The team carefully examined melt-inclusion volcanic glass beads retrieved during the Apollo 15 (July 26, 1971–Aug. 7, 1971) and 17 missions (Dec. 7, 1972–Dec. 19, 1972). Startling findings of high levels of carbon within melt inclusions, similar to amounts in mid-ocean ridge basaltic eruptions on Earth, have guided the researchers toward a degassing model of initial carbon monoxide-triggered fire fountain eruptions as facilitating the escape of hydrogen gas onto the surface for combination with oxygen in water formation.
The researchers’ model dovetails with the 2008 discovery of traces of lunar water by Alberto E. Saal via analysis of similar samples of volcanic glass and subsequent detections of a trio of volatiles: chlorine, fluorine and sulfur. The discovery of water and the detection of carbon’s degassing patterns attest to an active, volatile moon and suggest volatile commonalities for the interiors of the Earth and its moon.
The lunar profile that emerges in the early 21st century suggests a dynamic history that contradicts the cool, quiet constancy of Earth’s modern moon and tackles the enigmatic, pitted, scarred far side of the moon.
Moon fire fountains support William Shakespeare’s seeming lunar mistrust as evinced in Juliet’s disavowal: “O, swear not by the moon, th’ inconstant moon . . .” (Romeo and Juliet: The Balcony Scene, Act II, scene 2)
