The Morning After

Jun 9, 2011

On April 28, 2011, the visible-light and infrared sensors of NASA's ASTER satellite captured this image of Tuscaloosa County, Alabama, which had been raked by an especially large and powerful tornado just the day before.

Infrared sensors are useful for distinguishing between vegetated and non-vegetated land cover. The pink areas in the photo represent vegetation–forests, pastures, cropland, golf courses. Areas that show up as aqua are non-vegetated or very lightly vegetated–cities, highways, rivers, strip mines, recent clearcuts.

The tornado track is obvious here: a straight aqua-colored streak running from the southwest to the northeast. Vegetation in this streak that was not directly destroyed by the storm was so littered with pieces of buildings and household objects that satellite sensors could barely detect it.

Just north of the storm track is the twisting course of the Black Warrior River, which shows up in aqua. The city of Tuscaloosa is mostly south of the river, at the left edge of the picture.  In the upper left corner of the picture is Lake Tuscaloosa, a dammed-up tributary to the Black Warrior that provides the city's drinking water.

NASA's spokespeople assert that images such as this one can be useful in the aftermath of storms. They may help identify storm-damaged places outside of populated areas, where tornadoes might escape public awareness. And by proving the time and location of tornado paths, they could help homeowners support their insurance claims for storm damages.

If you click on the picture to see the larger version, you can follow numerous roads out into the countryside and observe that many of them seem to end with a little dot of aqua, indicating a non-vegetated spot. These are well pads for methane rigs. About fifteen years ago, the Black Warrior basin was the scene of one of the nation's first methane gas drilling booms. Coalfields underlie much of west Alabama, including almost all of Tuscaloosa County, but until recently the methane gas associated with coal deposits was considered a danger rather than an economically valuable fuel. "Fracking" technology, in which high-pressure liquids are injected deep into the earth to crack open the rocks hosting methane, was developed and refined in Alabama; drilling for methane is now under way all over the world. Unlike oil or traditional natural gas, methane is best extracted by small wells located within a few hundred feet of numerous other small wells; thus, the countryside is speckled with hundreds or thousands of separate well pads.

No Diving

Jun 3, 2011

Like most American local governments, the city of Philadelphia is pretty much broke and can't afford to operate its public swimming pools.

Two summers ago, the pools never did open. Last summer, neighborhood fundraising financed a few weeks of swimtime in July and August. This summer, we're told, fundraising has been successful enough to open the pool in our neighborhood for a few extra weeks, beginning in mid-June when school lets out.

Rumor has it that one Philadelphia neighborhood is financing its pool operation with a high-stakes Cowpie Bingo game. If you're not familiar with Cowpie Bingo, it's really one of the best games you can play with a rented cow. You mark a grid on a small field of grass and sell chances on squares in the grid; half the take goes to the cause–in this case, lifeguard salaries and tanks of chlorine–and the other half goes to the lucky person who bought the square where the cow deposits whatever she deposits.

The Philadelphia swimming pool cowpie bingo game is said to offer $10,000 to the winner, if the cow cooperates by depositing her pie neatly within a single square of the grid.

This may or may not prove a good financial model for twenty-first-century urban government. Until we know for sure, that No Diving thing is probably a really good idea.

First Salute

Jun 2, 2011

A few minutes after commencement and commissioning last Friday, in the parking lot outside the Naval Academy's football stadium in Annapolis, Maryland, the new ensign in his choker whites and shades got his first salute, from midshipman Aaron Kalil, who still has a year to go until his own graduation and commissioning.

Per tradition, the new ensign bought this first salute, handing Aaron a silver dollar.

Ensign Stein now begins five years of active duty in the navy. Midshipman Kalil begins a year as captain of the U.S. Naval Academy wrestling team. There was champagne all around.

Rust Belt Pie

Jun 1, 2011

Recently, Newsweek magazine singled out the three rustiest, dying-est dying rust belt cities in America; coming in at number three, behind Detroit and Flint, Michigan, was Grand Rapids, Michigan.

Grand Rapids–hometown of President Gerald Ford, corporate headquarters of Amway, hub of western Michigan's peach orchards and blueberry farms–didn't take that kind of ranking sitting down. Thousands of city residents stood up and took to the streets, lip-synching Don McLean's anthem all over town, producing the anti–rusty-dying video shown below.

Roger Ebert dubbed it the greatest music video ever. And Newsweek apologized, even going so far as to declare the published rustiness ranking to be methodologically flawed.

The picture above is Tranquilitea, a mosaic by Grand Rapids artist Peggy Kerwan made from thousands of tea bags. The bright colors are from tags and paper wrappers on the tea bags; the subtler shadings are from the translucent tea bags themselves.

The Little Packers

May 22, 2011

The caption is missing from this Lewis Hine photo in the Library of Congress, but it was taken in the year 1900 and is believed to show children who worked at a seafood-packing plant in Baltimore.

The Baltimore seafood packers were immigrant families who called themselves Slovonians; they came mostly from regions of Eastern Europe that would later become Czechoslovakia and Yugoslavia. After a few years in Baltimore, many relocated to Biloxi, Mississippi, which became the center of American seafood processing through much of the twentieth century. There is still a Slovonian Society and Social Club in Biloxi.

Lewis Hine's photographs of working children were part of his eventually successful campaign to end child labor in the United States. This picture is a bit different, however. If you click on the photo to view a larger version, you will notice that several of the children are clearly too young to pack fish; one is too young to walk. And unlike Hine's usual subjects, some of these children are smiling, even laughing.

Maybe the picture is a reject from the anti–child labor campaign, hence the missing caption. Perhaps the children were families of seafood packers, but not necessarily working themselves as seafood packers. But it is clear from Hine's other photographs that at least some of these children did in fact work long, miserable hours in the wretched factory they are posed in front of. They nonetheless laugh and smile, we have to assume, because that's what children do.

On the Sofa

May 21, 2011

Camille Doncieux was one of the favorite painting subjects of both Claude Monet, who married her, and Claude's close friend Pierre-August Renoir. Here, she reclines and reads for an 1872 portrait by Renoir.

Monet first met Camille in 1865, when he sought out models for his large-format figurative work, "The Picnic." They had two children together and finally married in 1870, around the same time that Monet and Renoir were working out the new approach to painting that became known as Impressionism.

Although Impressionism is widely associated with scenic paintings–sunlight sparkling on water, buildings reflected in the ripples–Impressionist-style portraits of Camille by both Renoir and Monet were much easier to sell in the earlier years than were the outdoor scenes. The two artists often used her as a model in paintings of gardens or city streets, perhaps to improve saleability.

Camille died young, in 1879 at the age of 32, from pelvic cancer. Monet painted her one last time on her deathbed. He and his two sons then retreated to his farmhouse at Giverney, where he remained somewhat secluded for the rest of his life, cultivating and painting his famous garden.

Patriot

May 20, 2011

This month's Patriot of the Month–shown above at left, with his brothers–is none other than our own Ted Stein, as proclaimed by the Bill of Rights Defense Committee.

Ted was honored for his work with the Center for Torture Accountability, an organization he founded two years ago as "a way to shame torturers and hold them accountable at a cultural level even if our government isn't holding them legally accountable."

The critical importance of a culture of accountability became evident to Ted when he learned of efforts by torture survivors in Argentina to bring stories of torture to the attention of the public, so that even when the government failed to prosecute, everyone would know that there were torturers living among them. Stories about the torturers showed up on walls all over town, and posters made the torturers' faces well known to the public at large.

It occurred to Ted that the internet could be used for similar purposes in the United States. We have torturers in midst, men and women who as part of our government, tortured thousands, likely tens of thousands, of people in the name of the fight against terrorism. We have tortured prisoners to death in some cases. Many victims of our torture have had no personal association with terrorism; they were in the wrong place at the wrong time, or were turned in by bounty-hunters. Some of them were children. Some of the acts of torture inflicted upon them are the same as actions for which we executed Nazis after World War II.

The Center for Torture Accountability attempts to make the American public understand the horror of what the government has done in our name, by ensuring that the stories of government-sponsored torture show up front and center in internet searches. The goal is to make sure that the names of torturers, and of the people who organized the American torture regime, will be forever associated in the public sphere with the deeds they did.

Torture and torturers thrive, observes Ted, in cultures of impunity; torture stops when the culture becomes one of accountability. We may wait a long time for the government to hold its torturers to legal accountability, but in the meantime all of us can begin the hard work of changing our overall culture, so that torturers are no longer accepted as good citizens or welcomed in decent society.

Where the Wild Things Are

May 17, 2011

On Highway 26 the other day, just outside of Dubois, Wyoming, in the Wind River Range, this grizzly and her cub crossed the road and scooted up the snowbank while Hank tried to snap her picture.

The snow thereabouts was still four feet deep in mid-May, which is why Hank and his friend Pat found themselves scurrying along Highway 26, south of Yellowstone, on their way back east from Montana. All over Yellowstone and the Tetons, late spring avalanches were closing highways, and the boys found their way blocked repeatedly; they backtracked, looped southward, backtracked again, looped further south, and finally broke out onto the plains.

Mallet Men

May 16, 2011

Every April, the town of Annapolis, Maryland, gears up for the annual croquet match between the Midshipmen of the Naval Academy and the Johnnys of the small liberal arts college across the street, St. John's.

Although the Naval Academy is an athletic powerhouse and St. John's is a haven for bookworms, the Johnnys routinely win the contest. But there is a non-athletic dimension to the event as well: costuming.

Spectators from both colleges show up in Gatsby-esque 1920s attire, notably including hats. And the St. John's team dresses in different uniforms every year, top secret till the day of the game.

This year, the Johnnys' secret uniform was . . . the same as the Naval Academy uniform, white pants with letter sweaters. The two teams were distinguishable, however, because the midshipmen wore shiny white dress shoes while the Johnnys wore whatever shoes they felt like wearing.

St. John's won, 3-1.

F4

May 12, 2011

The April 27 tornado that stayed on the ground for more than eighty miles through Tuscaloosa and Birmingham, Alabama, has now been classified F4, not F5, as I mistakenly indicated in a posting here on May 1. There were three definite F5 tornadoes that same day, including one in north Alabama that completely obliterated the town of Hackleburg.

But F4 is plenty bad enough. Forty-one people died in Tuscaloosa.

This is what's left of our old house. It was a two-story house, but the second story was set back a bit, and it's completely gone. At the extreme right of the picture is the doorframe for the front door, which is gone. At left is a spray-painted "Katrina cross" indicating that the rubble was searched on April 28 by search team "M," and no people or pets were found.

Not in Kakuma Any More

May 10, 2011

Alex Bial, one of the Lost Boys of Sudan, joins in the Pledge of Allegiance at the end of a citizenship ceremony in Burlington, Vermont.

Bial and the other Lost Boys in the United States came here after ten years or more in Kakuma, a UN refugee camp in northern Kenya; Kakuma is Swahili for Nowhere.

Some 20,000 boys from southern Sudan were separated from their families in the late 1980s when government soldiers swept across the southern part of the country, burning villages and attempting to enslave village children, especially boys. Families sent their young boys to hide in the forest, where they formed small bands that eventually came together in a massive exodus seeking safety in Ethiopia, hundreds of miles away across a war zone and a desert. They walked for a year.

Almost half of them died along the way. And after three years as refugees in Ethiopia, war again caught up with them and they were forced to wander for another year before finally reaching Kenya. Those who survived found strength in intense bonds with one another and deep commitment to nurturing the group.

Now scattered in communities across the United States, Lost Boys have raised millions of dollars to help refugees left behind in Kakuma. As of 2010, the camp held more than 70,000 refugees, families as well as Lost Boys, most of them from southern Sudan and Somalia.

The Sudanese civil war finally ended in 2005, and late in 2010 voters in the southern part of the country voted overwhelmingly to become a separate, independent nation, the newest state recognized by the United Nations.

Five Feet High and Rising

May 8, 2011

The Mississippi River is flooding now, cresting at Memphis near record levels and adding water from swollen tributaries as it rolls on south toward New Orleans.

By all accounts, flood crests along the southern part of the river will reach the highest levels ever recorded during the next ten days or so. Although little new rain is expected, snow melt from up north plus spring rains totaling 400 percent of normal throughout broad stretches of the Midwest and South have filled the river system far beyond capacity.

The worst recorded Mississippi floods–probably the worst single disaster in American history–came in 1927, when levees were overtopped and undermined in literally hundreds of places, stranding more than a million people in high water, many of them for three months or longer. Among the ironies of this disaster is its hero, U.S. Secretary of Commerce Herbert Hoover, who organized rescue and relief operations that were so impressive his performance propelled him all the way to the presidency the next year, in which office he stood idly by while the country sank into the Great Depression.

Depression-era public works projects improved the levees and supplemented them with floodways–gates in the levees opening onto back channels that could be intentionally flooded when necessary, taking pressure off the levees during high water. But the water ran even higher in 1937 than in 1927, and again almost a million people were flooded out of their homes. Among the ironies this time: the rains that caused this flood were what finally put an end to the long Dust Bowl drought.

Again, flood defenses were strengthened, and the next time the river ran really, really high, in 1973, flooding was severe but not catastrophic. However, the 1973 floodwater did damage the "Old River Control Structure," shown here, which is key to the entire lower Mississippi Valley as we know it–and which is at risk now, in the highest flood the river has ever seen.

The Old River Control Structure is a Rube Goldberg sort of complex designed to keep the Mississippi River from abandoning its channel and finding a new route to the Gulf of Mexico. Like all rivers, the Mississippi constantly tries to create new distributaries near its mouth, where it has deposited so much sediment that it's blocking its own flow. In the nineteenth and early twentieth century, the Army Corps of Engineers helped this process along by dredging new channels to shorten shipping routes and removing huge logjams that trapped river sediment. Year after year, more and more of the Mississippi left its banks and drained west through the Atchafalaya swamp, eventually reaching the Gulf near Morgan City, Louisiana, far to the west of New Orleans and the current river delta.

The Atchafalaya swamp drainage eventually scoured out a river channel, which could efficiently drain even more of the Mississippi water. Scientists predicted that by 1980, the entire river would reroute itself into the Atchafalaya basin, permanently flooding Morgan City and other communities near the swamp. The cities of New Orleans and Baton Rouge, with their huge ports, refineries, and other industries, would no longer be connected by a deepwater river to the rest of the country; a little water would still travel in the old riverbed, but it would become brackish, shallow, and slack, like all the other Gulf of Mexico bayous.

This would be economically devastating to the region and perhaps to the entire country, since we would lose massive amounts of petroleum and transportation infrastructure. New Orleans and environs would lose their drinking water and much of their economic function. The entire population of Morgan City would have to be relocated.

To prevent all this catastrophe, Congress passed a law against the Mississippi changing its course. Literally, the law requires that at least 70 percent of the river water stay in the current river channel all the way to the Gulf of the Mexico; only 30 percent can legally flow the way it now wants to flow, to the west through the Atchafalaya.

To enforce this law, the Corps of Engineers built the Old River Control Structure, which partially failed in the 1973 flood. They reinforced the original structure and added new auxiliary features to help out. The question now is whether this new control system can stand up to the record-level flooding of 2011.

If it fails, the lower Mississippi will most likely never again return to its banks. Already, in the forty years since the Control Structure went into effect, Mississippi mud deposited by the riverwater has built up the  Mississippi's bed near Old River till it is about five or six feet higher than the Atchafalaya river there; a hydroelectric power plant has been built on site to take advantage of the elevation drop, and a lock and dam had to be built to handle ship traffic. Obviously, if the river there were left to its own devices, it would respond to gravity like any other river and dive over this five-foot drop, hurrying along to the Gulf of Mexico, New Orleans be damned.

The key metric is three million cubic feet per second; that's the "project flood," the maximum flow the Old River Control Structure was built to handle. It's not been tested at anything close to that level; it will be tested now, beginning around May 19. We can hope.

The video below shows images from the 1937 flood, to the song by Johnny Cash recalling his boyhood experience of that flood in Dies, Arkansas.

Cheese in Every Language

May 8, 2011

Trekkers come from literally all over the globe to watch the sun rise over the Himalayas from the top of Poon Hill. And then, as soon as the sun is bright enough, they all take pictures of each other.

We met trekkers from the Netherlands, Australia, Israel, France, Japan, Ireland, Germany, and probably some other countries I've forgotten. The group in the foreground here was from China.

Very few came from the United States. Americans generally don't have the vacation time or the "hillwalking" tradition shared by the Europeans. However, patterns of tourism are changing; in the resort city of Pokhara, which we visited after our trek, we met a tour group of senior citizens from New Jersey.

Teatime

May 6, 2011

About a thousand feet straight up above the village of Ghorepani in Nepal's Annapurna region is the crest of Poon Hill, a vantage point where trekkers from around the world gather at dawn to watch the sun rise over the Himalayas.

Poon Hill is 10,500 feet above sea level, and it's cold there at dawn. Well before dawn, enterprising citizens of Ghorepani make huge vats of hot tea and carry them up the trail to sell to the trekkers. Here, a local dog shares a trekker's cup of tea.

Dogs are ubiquitous in Nepal. In the countryside, most of them look just like this one–medium-sized, square-headed, with a thick black coat and light tan markings. In the city of Kathmandu, the dog population exhibits more variety, but they still tend to be medium-sized, square-headed, and thick-coated. Dogs can be seen sleeping in the sun on sidewalks and streets all over the city. They live off garbage and scraps tossed out the back of restaurants and homes. They show no aggression toward humans and only a little toward other dogs; none of them, of course, is on a leash. Mostly, they sleep.

Ninetieth

May 5, 2011

Here we see yet another branch of the family, a cast of characters with international flair: my cousin Susan, at left, who lives near Toronto, Ontario; her daughter Erica, who is working on her doctorate in archaeology at Oxford University in England; and Susan's mother Ethel, who lives in Annapolis, Maryland.

Erica's research at Oxford focuses on what people ate in antiquity. She collects seeds and other plant materials from archaeological digs in the Middle East and and analyzes them in the lab to learn about their role in ancient diets.

This picture was taken a few months ago at Ethel's ninetieth birthday celebration. She is a young and active ninety, taking after her mother, who lived to be a young and active one hundred.

New Trees

May 4, 2011

Every fall and spring, civic organizations add new saplings to Philadelphia's complement of street trees. Here, our neighbor Carolyn Duffy points out proper technique last month with one of her tree-planting crews.

Carolyn is a volunteer "tree-tender" working under the auspices of Schuylkill River Park and the Pennsylvania Horticultural Society; she and her volunteer crews plant about sixty trees a year in neighborhoods near Rittenhouse and Fitler squares. This tree is going in across the street from the public swimming pool near 26th and Lombard streets.

It's a big operation. Trees this size–with trunks about two inches in diameter–are expensive, often $200 each, if not more. Growing conditions on each particular block dictate different varieties of trees; for example, only short-growing trees can be planted under power lines, and only narrow, columnar varieties can be planted close to parking spaces. Some narrow old streets are so dark that many kinds of trees will not thrive; other spots are so open and windy that big, sturdy varieties are most appropriate.

Nearby homeowners are asked to supply mulch and to make sure the new trees are watered during their first two summers. The Pennsylvania Horitcultural Society supplies urban arborists who match trees to sites, check up on the trees' health, and see to any necessary pruning.

This spring, Carolyn and the neighbors planted gingkos, sycamore-like London plane trees, Bradford pears, ornamental cherries, and pretty little oak trees. In the upper right corner of this photo, behind the man in the red hat, you may be able to make out the green leaves and white flowers of a pear tree planted just last fall. In a few more years, all the real estate ads for houses on these city streets will boast of "lovely" tree-shaded blocks.

Montana May

May 3, 2011

The snowline has retreated most of the way up the hillside above the campus of the University of Montana in Missoula, and the well-tended campus lawns have turned seriously green.

Still, the sky sometimes spits snow, and the trees daren't yet display a hint of green. If on some afternoons the spring air is gentle enough to warm an upturned face, you can take it to the bank that a few minutes later the wind will stir and whip and sting, and push the people back indoors.

Must be May in Montana.
