James and the Flying Horse

First Light.

It is quite a dramatic image. Four hundred years ago a man stands in his workshop, grinding lenses. Using the skills of a ‘Cooper’ (a barrel maker), the old man constructs a tube from wooden slats. He fixes the lenses to the inside of the tube, and on a dark night holds the tube braced against a part of the roof and gazes up at the bright point of light. It is a planet, a ‘wanderer” so called from the ancient Greek planetai. This bright point of light is one of several of the points of light in the night sky that are not fixed in the sky like the stars. They ‘wander’ across the heavens in a path that can be tracked. The man gazes through the tube with its lenses which magnify the object viewed. He is astounded by the beauty of the bright point of light, Jupiter.

This is the “First Light” of the first telescope. It is how I imagine Galileo looking up at Jupiter and seeing its bands and discovering Jupiter has moons.

First light is a meaningful event for a telescope or any instrument that is used to view and study the objects above us and beyond us in the night – or daytime – sky. It is the proof that the telescope or other viewing instrument actually works. When I built a simple helioscope/projector using an inexpensive Newtonian telescope to view the Transit of Venus, my instrument had a “First Light”. It was exciting. I knew the telescope worked but had I constructed the screen perpendicular to the stream of light from the telescope to get a good image? Was the material I used for the projection strong enough to withstand handling and yet thin enough to allow the image of the sun to shine through.

Yes it was. I had achieved First Light.

First Light is the end point of making a telescope and the starting point of using it for observation. It is fully told in the story of the Hale Telescope in Richard Preston’s book First Light. In this book he tells about the construction of the Hale telescope and its use in discoveries in the cosmos.

And then this year we have First Light from the new James Webb Space Telescope that sits at a gravitational stable position known as Lagrange Point 2, approximately 1,000,000 miles from Earth.

The James Webb Space Telescope is not only robust, but it is also beautiful. In pictures of the Telescope before it was folded for launch the purity of lights and image seem to rise from its surface to greet the viewer.

What was James Webb Space Telescope’s Frist Light?

It can be seen in an image at the top of this article. This image is admired around the world for its clarity and stunning splendor. The image was published by NASA, ESA, CSA, and STSci (National Aeronautics and Space Administration, the European Space Agency, the Canadian Space Agency, and the Space Telescope Science Institute) with the caption, ‘The Webb telescope‘s image of the galaxy cluster SMACS 0723 includes thousands of galaxies, including the faintest objects ever observed in infrared. The light in the image is 4.6 billion years old.”

According to NASA, SMACS 0723 was chosen as one of the first five ‘targets’ for the James Webb Space Telescope, due to it being a “massive galaxy cluster” an image of which shows the foreground clusters which “magnify and distort light behind them. This creates a deep and detailed view into the extremely distant and faint galaxies beyond.”.

The image shows a cluster of galaxies with one in the upper center dominating. The other galaxies of the cluster are the other large white objects around the center of the picture. The mass of the galaxy, including the mass of its ‘dark matter,’ results in the numerous arcs of lensed galaxies as light from more distant galaxies behind the cluster is refracted and bent by the gravity of the near field cluster into the numerous arcs of light. Many are ‘mirrored’ and are seen as two lensed galaxies connected by a curved arc. These are not different galaxies. They are the single distant galaxy whose light is bent as it passes the galaxy cluster.

But where is the winged horse?

That comes from a separate target of the Webb telescope, Stephan’s Quintet. The Quintet is a compact galaxy group located in the constellation, Pegasus, the Winged Horse. Four of these galaxies are tied by gravity into each other. Each of these four galaxies spins on its own but is held close by the forces of the other four galaxies. In the distant future the four may merge into a single massive galaxy. The fifth galaxy of the Quintet is distant and has less of an effect on the others.

Stephan’s Quintet will be a target of my own star gazing after Pegasus rises to its best viewing position in the sky during the cool nights of October. It is perfect weather for star gazing, less moisture in the atmosphere bringing clear nights.

Fighting Climate Change

“Give me a fast ship, because I intend to go into harm’s way.” John Paul Jones

In this decade, the nations of the world must come together to protect our Earth from the effects of our industries of the last several hundred years.

Our vessel must be worthy, if it is not, we will not succeed.

The 2021 report by the Intergovernmental Panel on Climate Change (IPCC) will be the starting point of these Stone Fig Climate Change postings. The IPCC is a body of the United Nations tasked to assess the science related to climate change. Created in 1988, the objective of the IPCC is to provide all levels of government with scientific information that can be utilized in developing climate policy.

Its website may be found at IPCC — Intergovernmental Panel on Climate Change.

The IPCC not only provides information to the nations of the world but to each of us as well. It is appropriate that we should understand the reports by the IPCC. Our nation and other nations will use this 2021 Report, and the reports that follow, to establish climate change policy and regulations.

To support our country, we the people, must have a basic understanding of the chemical and physical processes within our Earth’s climate. We should be able to understand and have a reasoned opinion on the actions developed to combat climate change. The basic principles and ideas of climate processes can be easily found, and refreshed through numerous sites on the internet.

When we read the reports and the proposed laws and regulations it is appropriate for us to use our personal skills of critical thinking to determine whether the proposed regulations are supported by the science. The regulations passed and the support we give to the enforcement of those regulations will determine whether we have a “worthy vessel” and whether or not we will, in the end, succeed.

I will focus my Climate Change postings on reading the documents published by the IPCC. I will start with the Summary for Policymakers (SPM) from the 2021 United Nations Climate Change Report. The SPM may be found at IPCC_AR6_WGI_SPM_final.pdf.

The SPM begins with an assessment of “The Current State of the Climate”. In this assessment reference is made to “AR5” which is the IPCC 5^th Assessment Report (AR5). The SPM states that since AR5 was released in 2013 improvements have been made in recording the geologic records of ancient paleoclimate. These ancient records are reached by taking core samples of glaciers, tree rings, and sediments from the ocean floors. These core samples can provide us with climate records that reach back long before the early industrial age of the 1700s and 1800s. According to the United States Geological Survey (USGS) the study of Paleoclimate provides an essential perspective for assessing the potential impacts of future climate on “natural systems and the people who rely on them”. Scientists use the geologic evidence of past climate changes to understand the rates and patterns of Earth systems’ responses to a broad range of climate and landscape changes. When integrated into climate models these paleoclimate data provide a means to improve our understanding of the impacts of climate change.

When we review just the last 100 years, we can see the beginning of a significant increase in average global temperature. This is shown in Figure SPM.1 of the SPM. The graph is shown below.

In my view, after the Second World War (1945) the nations of the world, led by historically industrialized nations and nations with the resources to become industrialized nations, began a significant increase in activity These activities reinforced the change from farm-based/agrarian activities as primary human-activity to that of industrial-labor activities which had begun in the 1800s. To support these industrial-labor activities our collective power requirements for light, energy, transport, and transportation increased apace with this change.

This increase can be seen in the graph above.

It can be seen from the graph that in the last 50 years the average global surface temperature has increased at a average rate of 0.018 degrees Celsius (C) per year. This is an increase of 0.9 degrees C in 50 years. The upward angle of the graph will likely continue to rise if something is not done. What is “something”? It is action by each person, by every nation, to reduce the effect of human-activities that contribute to the increases in average global temperature.

To borrow a phrase from the movie Jaws, “We are going to need a bigger boat.”

We are in need of a revolution against our own past.

I am not saying the past was wrong or evil. Those activities built a standard of living for the people of the industrialized world who should now help raise the standard of living in the non-industrialized world.

We are on the threshold of a new age. We will step through; but what will we find?

If we do not address the rising global temperature and the changes to the climate it is causing, the poorer will suffer even more, and the rich will become poor and suffer as well. If we address the issues of climate change we can likely maintain a standard of living and can raise up those who do not yet have it.

In the pictures below of heroes of the American Revolution we see the spirit of the men and women who chose to fight to bring change to their way of government. Would they be ruled, or would they govern themselves?

We have to fight again, but this time against ourselves. We must use our individual critical skills to determine what actions each of us can take and should take. Then we must act!

The future does not belong to the timid.

We are all called. These pictures of John Paul Jones and Molly Pitcher (Mary Hays/McCauly) call to mind the fight that is ahead and the determination with which we must face it.

Their fight was for a new nation in a new world. Our fight is one to save the world for ourselves, for our descendants, and for all of life on the planet.

Look out for the Pendulum

NASA photograph of Apollo 16 Astronaut next to Plum Crater on the lunar surface. The “Moon Buggy” is in the background.

I am not making this up – well, mostly not.

On the surface of a distant moon, a lone space traveler steps away from his companions and approaches the edge of a large pit. It appears nearly round with no crater wall. He approaches the edge carefully. Then suddenly the lip slides-out beneath him, and he rolls down the side tumbling towards the apex of the cone shaped pit. All he can call out in his soft Texas drawl is, “reminds me of a doodlebug hole”.

I exaggerate, no astronaut fell into a pit, nor was one paralyzed and devoured by an extraterrestrial Antlion. But a similar discussion took place on 24 April 1972 during the third “extra vehicular activity” (EVA) by the crew of Apollo 16 while exploring the surface of our moon in their “Moon Buggy”.

The discussion of the doodlebug took place 240,000 miles from the closest doodlebug as Astronaut Charles Duke described a part of his childhood in the southern United States to the folks at Mission Control.

When I grew up in rural North Carolina, doodling Antlions, also known as doodlebugs, was part of what we did. We did not have a TV. We played outside and ran to the river and splashed and played in it and ran back. On our way up and down that dusty lane, we might see that dimple in the sandy ground of an Antlion’s nest. We generally called them doodlebugs, and we sought to bring them out of their hiding at the bottom of their conical pit. We would disturb the side of the pit gently with a bit of pine straw to see if we could bring the tiny beast out from his hiding place at the bottom of his trap.

These tiny larvae are ferocious looking with jaws nearly half as long as their body, with sharp fangs for grabbing and devouring their prey.

My attention was recently turned to Antlions by an article in Science News which described a study of the Antlion behavior of “throwing sand” upwards from the bottom of its pit. The Antlion of the southern United States is the larval form of Glenurus spp of the family Myrmeleontidea. This family designation is explained by Barb Ogg on the website of the Nebraska Extension Service at the University of Nebraska-Lincoln. “The Antlion family, Myrmeleontidae, literally means Antlion family (myrme = ant) + (leon = lion) + (idae = family). Antlions belong to the insect order Neuroptera, most of which are predators.” The designation “spp” means plural or multiple species. A picture of an Antlion is shown below.

The authors of the Antlion paper studied the Antlion behavior of throwing sand. It was determined that this action is useful in maintaining the correct geometry of the trap the Antlion digs as well as aiding the Antlion in capture of its prey.

The Antlions trap or “pit” is dug in sandy soil by the tiny beast by using its broad body as a bulldozer and working the sand in ever decreasing diameter circles as it moves backwards until the pit is dug. The pit is an inverted cone. The Antlion buries itself at the center of its pit and waits for its dinner to walk in.

Antlion behavior has been observed by countless generations of children who live in areas with sandy soil and also by the adults that the children grew into. After digging its pit the Antlion will lie in wait for its dinner. When a small insect like an ant enters the pit, the sand on the slope of the pit will often give way and slide, with the insect, down to where the Antlion may capture it. However, not just any angle for the slope of the pit will suffice. The trap needs to be constructed so the sides are inclined downwards at an unstable angle. This angle is technically discussed as the “angle of repose” of the soil. A slope less than the angle of repose is flatter and stable and will not shift except under significant pressure. However, a slope greater than the angle of repose is unstable. This means that as a tiny insect like an ant tries to crawl out of the pit, the unstable sand will slip and slide towards the bottom of the pit.

When the Antlion notices the vibration of the ant’s footsteps and the vibration of the falling sand, the Antlion will begin to fling the sand from the bottom of the pit up onto the sides of the downward slope. As described in the study, this produces two results. The prey becomes confused due the torrent of sand falling on it and will be more likely to tumble into the center of the pit. Second, the sand being flung by the Antlion by flipping its head like a shovel, removes the sand that has fallen into the pit and throws it onto the sides of the pit to maintain an unstable configuration of the slope. By these actions as the Antlion’s dinner is tumbling downward, the trap is being set for another insect.

According to the article by Barb Ogg, as well as other articles, these tiny insects do not bite humans nor do they damage plants, so they may be left alone.

I have heard that Antlions respond to singing or chanting a ditty such as “Doodlebug, doodlebug, come out and play”. As fun as this might be there is no proof of its efficacy. However the vibrations of our voice may dislodge sand on the unstable sides of the pit causing the Antlion to investigate the event.

The NASA transmission of the EVA (extra vehicular activity) may be found at https://www.hq.nasa.gov/alsj/a16/a16a1690707.mp3. At time 0:58 Astronaut Clark refers to the structure on the moon’s surface as a “doodlebug hole”. It starts out rather loud and you may want to turn it down. In the discussion, the depression is referred to as an endogenic crater. An endogenic crater is a pit formed by processes beneath the soil surface like a gas bubble moving outwards and erupting through the upper soil layer, or perhaps like a sinkhole. It is not an impact crater.

The transcription of the .mp3, plus other transmissions not recorded in the transmission, may be found at Return to the LM (nasa.gov) starting at the entry for 169:07:53 and going through 169:08:25. The transcription of the conversation contains more information of what was said than the .mp3 recording. Perhaps it was on a separate channel.

This article’s Title refers to the tale by Edgar Allan Poe, which is a tale of another conundrum.

Forbidden Planet

I remember the flashing lights on the screen of the darkened movie theater and the actors’ screams that I did not understand.

But yesterday when I happened to see on my television the movie that had so frightened me as a child, it was like seeing an old friend.

I was four years old when I went with my older brother to see The Forbidden Planet, a science-fiction movie that he and all his friends wanted to see. I had probably begged to go along with him, and since it was a rainy day my father decided that he would come as well. The three of us, who more often were found on an Autumn afternoon out hiking along the seashore or playing ball in the yard, were walking into the only movie theatre in town.

When I got scared my father had to walk me out and let me sit in the lobby. He watched the end of the movie through the door to the theatre. I had nightmares after the movie, and I did not like to have the lights turned out in the room I shared with my brother.

I have always remembered going to that movie and my reactions later at home. But I have always cherished the memory. When I pass the theater, which is still in operation in downtown Newport, RI, I think to myself of the time that I went there with my father and my brother, now both gone. And I smile. I smile not because of my childhood fears, but because I was with my father and my brother and they looked out for me. So my adult memories of the movie are happy memories.

But what about the movie itself?

As I watched it the other day, I recalled the scenes of the underground civilization, of “Robbie the Robot”, and the encampment of the space men outside their ship. But I also saw other things that I could not have seen then. I saw the amazing color of the old film, now digitally restored. I saw scenes that I recognized as being repeated in Star Trek and Star Wars. I watched a plot unfold, not of discovery, but of finding terror inside one’s self.

The premise of the movie is that twenty years prior the spaceship Bellerophon had left Earth to explore the fourth planet orbiting the star Altair. Altair is the 12th brightest star in the night sky. It is part of the Constellation Aquilla, the Eagle. The star is also part of an astronomical asterism (pattern of stars) known as the Summer Triangle. The other stars in the triangle are the star Deneb (19th brightest in the night sky) in the constellation Deneb (the Swan), and the star Vega (5th brightest star in the night sky) in the constellation Lyra (the Lyre).

In the plot there had been no signals from the planet for twenty years. The United Planets Cruiser “C57-D” was sent out to Altair to determine if there were any survivors. As it turned out there were two survivors, Dr. Morbius and his daughter, Altaira, played by Walter Pigeon and Anne Francis. The Commander of the C57-D, J.J. Adams, was played by Leslie Neilson.

Millions of year ago the planet had been the home of an advanced race, the Krell. They had developed their science and technologies to the point that the negative thoughts of their subconscious had taken the shape of a beast. The Best ravished their civilization and killed all Krell. All the scientists and crew of the Bellerophon, except Dr. Morbius and his daughter, were also killed by this electrostatic, but invisible, beast.

Dr. Mobius has not yet determined the cause of the beast, which returns as his thoughts turn against the crew of the C57-D and his daughter, who plans to leave with them.

So much of science fiction is about the initial exploration of space, and exploration and exploitation of the planets and civilizations that are discovered. The movie is an exploration of the human mind and how it can become lost in its prejudices and dislikes. His thoughts became a beast that destroys all.

If there is a moral to this story, it is that dwelling on the negative will be destructive. Forgiveness may provide a way out of unbearable troubles. If Morbius had not distrusted the crew of the arriving space cruiser, would the beast have reappeared and destroyed him?

This was a film that forecasts future developments in the science fiction genre. Its premise and its questions are echoed in the Star Wars trilogy, as are its flowing introductory script and some of the visual aspects of the Krell’s home world.

In the night, the beast we hear is often of our own making.

UPDate – Sails from Sweden

This article is an update on modern wind-propelled ocean-going ships. This was previously discussed in the article, Cylindrical Sails, posted October 1, 2018.

Naval architects and marine engineers are continually working to make ocean transport of cargo more environmentally sustainable. The vast majority of the world’s cargo whether it is manufactured goods (farm machinery or transistors/semiconductors), raw material (food stuff or metal ore), or consumer products (small appliances or clothes) are transported from point of origin to buyer by ships.

The map above is a screen shot on a summer day in the Northern Hemisphere. The number of ships traveling between ports can be seen crowding the favored shipping lanes. Other areas of the ocean are nearly empty in comparison. These shipping lanes are crowded because they are the most direct routes between ports of call. The most famous route being the Great Circle Route.

I remember as a boy seeing the ship I was traveling on being marked on its daily passage with a magnetic ship on a wall size map of the oceans. When I asked why the ship was moving up towards the North rather than going straight across the ocean, I was told that we were on the shortest route, the Great Circle Route.

This route is the shortest distance across the globe of the Earth. By taking the shortest route the ship takes less time in its crossing, thereby saving expenses and fuel costs.

The graceful arc of a Pacific Great Circle Route is shown as a black arc between Asia and North America (California). The congestion of this route can be easily seen. These routes can be made between any two ports on an ocean. Although they become more flattened near the equator and form an upside-down arc in the Southern Hemisphere.

In the last half of the 20^th century people began to realize the damage to the atmosphere due to the amount of fossil fuel being burned. This included ocean shipping which at the time burned “bunker oil,” a fossil fuel whose use and emission added tons of pollution to the atmosphere and to the sea each year.

Modern vessels use diesel generators and more efficient power plants to generate electricity that is use to drive the propellers that push these ships. The trend has been from direct drive systems for propulsion (a boiler generates steam to turn a geared shaft on which is mounted the propeller), to an indirect-drive (a diesel generator produces electricity which runs an electric motor to turn the shaft on which is mounted the propeller).

All of these systems use fossil fuels for their main power. Over the years the fuel efficiency of the ships and their engines has greatly improved. This was brought about through improved design of the vessels and their power plants. The results have been reduced operating costs as well as reductions in environmental contamination. At the same time the number of ships transporting cargo has greatly increased. The cargo tonnage offloaded in the Port of Los Angeles, California has significantly increased in the recent years. From 2000 to 2019 the general cargo off-loaded in the Port of Los Angeles more than doubled. It rose from approximately 82 million metric tons to more than 190 million metric tons. All of these goods were transferred by ships burning fossil fuel.

In order to reduce the effect of fossil fuel on the world’s atmosphere and oceans, a consortium being led by Wallenius Marine and including the KTH Royal Institute of Technology in Stockholm, Sweden and SSPA, a marine consultancy, have designed and tested models of the hull design for a modern sailing ship. These tests have been on the open water and in a testing basin.

The modern sailing vessel they are designing is a wind Propelled Car Carrier (wPCC). Wallenius Marine is leading the design of the wPCC. This type of vessel is used to transport manufactured cars and trucks. It is often referred to as a roll-on roll-off (RORO) vessel.

While the sail mentioned in the previous article was a spinning cylinder, the wPCC sails resemble the rigid sails of modern racing yachts. They are expected the propel the Car Carrier across the oceans and achieve a reduction in emissions is 90%. However it is noted that the vessel is slower than a standard RORO.

The sails have yet to come to a final design. These rigid sails will rise up from within the ship. They can also be lowered when the ship is under the control of tugs while in port.

And although I might think that I cannot wait another moment for my new Volvo to arrive, knowing that its transportation had a significantly reduced carbon foot-print is worth the small delay before I have the keys in my hand.

Boats and Clouds

Several decades ago I had an opportunity to go to the Union of Soviet Socialist Republics (USSR). I saw places that I had not seen before, and I talked to people about all types of things. I was even asked if I had any Blue Jeans to sell. It was funny. The guy who asked me that was an American who at that time was working for the CIA. Now I think he is in jail.

We were there for three weeks and started in Moscow and the area around it. I was profoundly moved by the World War II memorials. The USSR lost more than 20 million people, some died in internal struggles, others died fighting the Nazis.

As part of the trip we also traveled out to Odessa in the Ukraine and then north to Lithuania. Both were part of the USSR at that time. Lithuania became an independent republic in 1990, heralding the collapse of the Soviet Union. The Ukraine followed and became independent in 1991.

Lithuania is a truly beautiful place. We stayed in the city of Vilnius, the capital of Lithuania. The country’s northern climate supports vast forest of conifers and hardwoods. These forests include Larch, Spruce, Birch, and Aspen. The geography supports many stream and lakes, many of which flow north towards the Baltic Sea. It was Fall when we were there, so it was too cold for swimming. And even in summer, I can say from experience, the Baltic Sea is cold on the best of days.

One day we traveled out from Vilnius and visited the Lake area near the historic town of Trakai. The lake shores were ablaze with late Fall color. The Latitude of Trakai (54^o37’N) is approximately the same as the south end of Hudson Bay in Canada. We wrapped up against the Fall chill and walked out into the forest that lined the lake shore. The paths were narrow and wound back into the forest.

On the lake I had hoped we might see an over-wintering Red-necked Grebe (Podiceps grisegena). If there were any wintering birds, we did not see.

The isolation and depth of the forest assured me that in their season they are full of the songs of Lithuania’s native birds. And I was sure that the lakes teamed with ducks on their migration to the far North, or perhaps to this very spot.

There was a lake house. And there were row boats. Being fond of rowing in any season, I asked if there was time to go out onto the lake for a bit of a row. Our host apologized and said we would need to stick to our schedule. I am certain he was sorry that we did not have time. Sticking to the schedule during the times of the Soviet regime was important. I accepted it and apologized to our hosts to relieve him of the burden of not being able to allow such a small excursion.

A heavily traded commodity of the region from pre-Roman and into modern times is Amber, the fossilized resin/sap of ancient conifer trees. Amber is an organic near-gem quality stone. It has a rare warmth of color and can be polished to brilliance. Some Amber, when polished, and if clear, may be seen to contain an ancient beetle or ant. The Amber of the Baltic region is from the Eocene epoch and was deposited about 40 million years ago. Any bugs found in Baltic Amber would not have been the gadfly of the dinosaurs. Deposits of that type were laid down over 66 million years ago and are not found in the Baltic region.

In my visit to this region of frost and magical lakes I received a set of cuff links made from Amber.

The Amber of my cufflinks is clouded from the minerals and tiny air bubbles trapped in the flowing tree sap. The face of the polished Amber shows streamers of milky white. It is a cloud of ancient air and minerals trapped in a scene of golden earth tones. The outside surface of the Amber, the “rind”, is just as fascinating with its deep browns and reds from reactions of the ancient resin to the overburden soils that held the raw Amber. The rind is also deeply pitted from its burial for millions of years.

To touch Amber is to touch earth, sky, and water.

Walking in the Water

When my children were younger, we went out West.

We were on a two-week holiday, and there were sights we wanted to see. We flew into Albuquerque, New Mexico and then drove in a rented car to see cliff houses at Mesa Verde, the Grand Canyon, the Virgin River, the Very Large Array, Santa Fe, and the Four Corners area. We had a full list of places we wanted to see.

When driving between our various destination, we would stop beside the road for lunch. There are often picnic shelters in scenic rest areas on the highways. We would also pull off the road at a convenient spot and make sandwiches of fresh tomatoes and bright orange cheddar cheese. They were easy to make and always delicious.

In the first week of our trip one of our destinations was Zion National Park in Utah. We wanted to hike the Virgin River. The drive into Zion National Park is magnificent. The natural rock formations and the engineering and construction of the road join to make a stunning drive down to the canyon floor. But the best was to greet us at the bottom of the canyon. We had arrived at our destination, the trail head for The Narrows of the Virgin River.

The Virgin River flows through a deep natural gorge that the River has carved out of the native sandstone over the millennia. The trail that leads up through the Narrows is the Virgin River itself. Make no mistake the footing on the large and small stones on the River’s floor is always changing, and it is slippery and challenging. When you start your hike through the waters, you are going up stream. You are hiking against the River’s flow.

Please note that the National Park Service has sets safety limits for protection of the visitors, whether seasoned hikers or children. You need to check in at the Ranger Station to confirm that the River is safe for hiking and to get advice on the distance you will want to go. We did not want to hike the ten miles (round trip) up the River to Big Spring and back. We wanted to spend about an hour in the River. The Park Rangers were able to give us good advice on how far up the River we should go.

We stepped into the River. We could feel the current gently pushing against our ankles as we started our trip upstream. We smiled at the exhilaration. Later we would be laughing out loud at the joy of moving through the current as we continued on our upstream challenge.

And I will say, the challenge is worth it. To walk ankle deep and knee deep and up-to-waist deep against the current – struggling to set your feet firmly on the rocks you cannot see under the rushing water – and to suddenly plunge into a deeper pool – it is truly exhilarating. Even a hike of 300 to 400 yards up the River is memorable. To stand with your companions holding onto them and your walking staff for stability – and looking up out of the nearly quarter mile deep gorge – and seeing the clouds overhead is wonderful. You do not see them move; you feel that you are rotating under the still, white clouds painted onto a pure blue sky high above.

As we moved upstream one of us would suddenly disappear into the water after slipping on a rock, or stepping into a hole. Then we would rise up laughing to the relief of our companions who were shocked at our disappearance as if it were miraculous, followed by an equally miraculous reappearance, laughing, as we burst up from the flowing stream.

On the way back we talked about flash floods and the impossibility of escape in our situation. This is the reason that you must know the weather happening miles up the River. Up there a sudden rain-storm can dump tons of water into the stream and change a fun and challenging hike into a thundering, roiling disaster.

The flow urged us along on our way back to the trailhead. The rocks were just as slippery, but we were use to finding our footing. Soon we were back at the trail head, and in the car, soaking wet, and laughing uproariously at our adventure.

Remember:

The River doesn’t care.
The River can be dangerous.
Check conditions with the Rangers.
Know the weather.
Know the capabilities of the people you are hiking with.
Laugh.

In researching this article I read that the River is currently contaminated with a toxic cyanobacteria. Make sure you read up on the conditions in the River before you go. It might be an amazing drive, but if you can’t hike the River it might be a long trip to disappointment. https://www.nps.gov/zion/planyourvisit/toxic-cyanobacteria-bloom-in-the-virgin-river-and-the-streams-of-zion-national-park.htm

Visit the NPS site about hiking the Virgin River before you go. There is information there that will make your hike more enjoyable – and may save your life. https://www.nps.gov/zion/planyourvisit/thenarrows.htm

Shooting the ISS

I would go out to Manassas on cold winter mornings and watch the International Space Station (ISS) pass overhead. For me it was also a chance to go out and enjoy the crisp winter breezes and the sounds of the fields and forests on those cold winter mornings.

Overhead there is a silent rustle of an owl’s wing. Beyond me in the field I hear the deer snorting, NH-SNPHFF, as a deer clears its nostrils to get my scent. I can just hear the accompanying stomp of its foot. The deer are close at hand.

I stand quietly to listen for other sounds of the woods. To the west in the largest stand of hardwoods I hear a Great Horned Owl calling. A resonant, deep bass call, it is a chilling sound. It echoes through all of Creation. that surrounds me.

My eyes have adjusted to the darkness, and I look up.

I suck in a breath of cold air as I see the piercing points of the stars and planets far above. I have chosen a moonless night because the darkness will be deeper, and the stars and planets will stand out with greater clarity.

I orient myself. There is the Big Bear/Dipper (Ursa Major), and it shows me the way to Polaris, the North (Pole) Star, at the tip of the tail of the Little Bear.

Whenever I see Polaris, I always ask myself, Why does the little bear have such a long tail?

I look at my watch. I have twenty minutes before the ISS passes overhead in its orbit. It will reflect light from the still-hidden sun and shine as bright as any star in the night sky.

Before I set up my camera I lean back against my car and look up. I can pick out a few constellations and primary stars. I see a smaller satellite pass overhead. The satellite is a moving point of light among many stationary points of light (the stars and planets).

I want to eliminate any extra movement of my camera as that will blur the stars and gives them “tails”. However for satellite photography, including the ISS, I want the photo of the object to show a tail/trail so you can pick it out on a print where the stars are points of light. The satellite will show a tail/trail of light because of its movement across the sky.

I set up my tripod with my camera mounted on my home-made Azimuth Tracker. The Tracker moves the camera in relationship to the axis of the Earth so the stars will remain as points of light. The satellite will have a tail/trail in the photograph.

And I am ready.

I have been out for about 30 minutes. The time for the shuttle’s arrival and procession across the dark sky is near. I watch the southwest quadrant for my fast-moving target. As it appears, I depress the plunger on my locking extension cable to open the camera’s shutter (I am using film).

I count the seconds as I turn the crank to move the Azimuth Tracker and my Camera. Within three minutes I am done.

The wind has picked up, and the eastern sky is beginning to show a little light.

As the light grows in the east, I pack my camera and other gear into the trunk of my car. And then I lean against the car to again look up into the still dark sky. I see another small satellite swim through the darkness. An early bird is disturbed by my presence. It flies out of the Walnut tree and into the darken sky.

I know that is a hint that I should leave for the start of my day. I climb into my car and head into work.

After the film is developed and prints made, each picture carries in it the coldness of the early morning, the feel of the wind, and the sounds of the open field.

My picture at the top of the article shows the trail of the ISS. And the stars have short tails from the not-perfect alignment of my Azimuth Tracker. And the tail/trail of the ISS shows giggles form the wind.

Diving at Subic Bay

The USS Leonard F. Mason, DD-852, had left the line off the coast of VietNam, and we had brought her to Subic Bay for some repair and some recreation.

People often asked, “What do you do on the ship all day?”

We worked. We worked hard. There were watches to stand. There were repairs to be made to the ship and its equipment. There was underway refueling and resupply. And occasionally there was inflight refueling of a helicopter flying out on a rescue mission. There were orders to be fulfilled and support of our troops fighting for the freedom of people in southeast Asia and around the world.

Look at VietNam now. Through our efforts we helped ensure a better future for the people not only of the south but for all of VietNam. Do you question this? Look at the country now. It is prosperous, both North and South. And the people enjoy a level of economy and freedom that they never dreamed of under totalitarian regimes. But this came at a tragic cost including the death of 58,318 Soldiers, Airmen, Marines, and Sailors/Coast Gaard.

To the hundreds of thousands of young men and women who answered their nation’s call and went to serve on foreign shores, Thank You. You might have been scared. You might have been wounded. You might have returned to an ungrateful nation. And I am certain that you had friends who left their young lives behind. But you SERVED. You did not hide behind a Doctor’s note. You did not hide from the mail. You stepped forward and served. THANK YOU.

When the ship left the gunline for a return to port for replenishment and repairs, the ship’s crew also had a chance for liberty and relaxation.

There were many things to do off base at Subic Bay. One thing that many of us we enjoyed was the beauty of this part of the Philippine Islands. In particular there was an island that was used by the SEALs for training that was also open during the day for the use of its beaches. It is now called (on Google Earth) Grande Island. I am sure it had another name back then. And there was no resort hotel as there is today.

We hiked across to the south side of the island, facing out to the wide Pacific, there was a small beach of rocks, and clear water, and a deep hole or two that was marvelous for snorkeling.

The water was crystal clear and alive with fish. Periodically we would have the hair stand up on the back of our necks when we would see a Black-tipped Reef Shark watching us. And maybe there would be two of them.

We watched out for each other. It is always good to be cautious.

There were deep holes for diving. And for as long as we could hold our breath, we could have some good bottom time at around 30 feet, marveling at the fish which fed in the corals.

As we came up out of this blue-zone, the colors of the corals and fish became more vibrant. The sea water muted the colors, as it absorbed much of the sunlight. However, while restricting colors in the red, orange, and yellow wavelengths, sea water allowed the passage of blue light.

From above the water these holes might look like they are lined with blue-black rock. It is only when you are in the water, that you can clearly see the coral formations with its varying colors and shades. Only then can you see the multitudes of marine life feeding and minding their own business until they become lunch for another species of marine life that is only doing its business. When you look down into the corals as you float on the surface and peer through your face mask, the web of life of this tiny spot on a Pacific shore becomes visible. And you cannot leave unchanged.

On our hike back to the boat landing we talked about what we had seen. We talked about home and friends. We talked about when we might get home. And sometimes we might have to push off the jacks who had too much beer or too much war. And then we returned to the grey, steel hull that was our temporary home, for another watch.

Later, and much later, we remember the fish, and the sharks, and the sea-child’s teddy we saw on the side of the deep hole on the shores of the Pacific.

A good article on the absorption of light by seawater may be found in the Woods Hole magazine oceanus, at https://www.whoi.edu/oceanus/feature/shedding-light-on-light-in-the-ocean/

The photograph is the Black tipped Reef Shark was found on a Wikipedia article titled “Blacktip Reef Shark”, with a credit to https://www.whatsthatfish.com/image/view/6882. Note the blue coloration of the deeper corals beneath the shark, which is in dappled by the sunlight close to the surface.

Stone in the Woods

Which is it? A Stone? Or a Rock?

Was this photograph a picture of a stone, or was it a rock? I thought back to where I had seen this particular item of curiosity with distinct stratification (the lines of varying colored layers). I had been in the foothills of the Blue Ridge mountains of Virginia hiking one of the many the grand trails .

These trails are wonderful in all seasons. They wander up beyond the railroad tracks and the old mill, up into the ridges and valleys of these foothills. There are old stone structures deep in the woods to marvel at, and there are streams that in Summer are great for cooling one’s feet off. In Winter the trails are generally passable. But the streams are more often than not frozen over but not to support a hiker’s weight.

There are other ruins up in these hills, and graves of the men and women who pioneered this area. It is one of my favorite places to wander, especially in the Fall as the leaves are changing. The trails wander and seem to take me different places than they had before. And if its a cool day and I’m not too tired I might push for the summit which is not that high, but it sure is steep on my side. The other side? Well, that is a solid rock face and straight down.

So is this a picture of a Stone or a Rock? For me, a stone is something that I can pick up easily and fling over the water to make a splash. A Rock, for me is a different matter. There is no flinging a Rock. UMPHH! You pick it up and carry it someplace. Then you put it down. UMPHH!!!

In the space under the back porch of my house, there is a Rock that I uncovered while clearing an area to store my wheelbarrows. After I had uncovered something three feet in length and a foot in depth and realized there was no end or bottom in sight, I left it and worked around it. That is a ROCK. But I have moved Rocks before. While a boy scout, we moved a massive Rock to create a fire platform for our council campfires. That rock was as big as most of us, and probably weighed more than any three of us. That was a long, hot day. The platform looked really good when it was done. And the fires were brighter and our ceremonies better, because of our work.

While trying to determine whether my classification of Big = Rock, Small = Stone was correct, I first turned to my narrow Vest Pocket Webster Dictionary by World Publishing Company. I had bought it the early 1960s when my high school English teacher, Mr. Miles McNiff, told us that we should buy one and keep it as a ready reference in our desks. I used it, as I assume my classmates did, to confirm spelling of words I wanted to use in my essays.

Now of course this function is pretty much taken care of by our computers which highlight in red these words with which it disagrees. But I keep the small dictionary around even though its usefulness may have been taken over by the computer. I will say for this and many other items of good guidance, Thank you Mr. McNiff.

In this dictionary I found definitions for the two words, Stone and Rock. Stone is defined solid non-metallic mineral matter. Rock on the other hand is a mass or pieces of stone. Hmm, says I, (apologies to RLS), since the definition of rock includes the words “pieces of stone” as if broken or chipped away, then Stone must be more massive.

But I will disagree and stay with my understanding. A Stone might be big, or much smaller, such as a stone in my shoe. But a Rock for me is generally bigger.

Here, in the hills, I had photographed a Stone. It was barely bigger than an Oak leaf recently fallen. I saw as it lay upon a cold hill side, reflecting the filtered light from above in its beautiful, lined quartz.

I wanted to ask the Stone what had happened in each of those lines, the narrowest of which was likely thousands of years in the making. Or perhaps it was a single flooding event. But over the eons that stone was laid down and then under the pressure of many million more years, it became Rock.

Then later it was up thrust in some gigantic earth-quaking event, perhaps the lifting of the mountains to my West. And as the layers of strata became once more exposed to light, and heat, and cold, and snow and rain, and the pressure of roots and of freezing and thawing, eventually this squared Stone fell off its perch.

Crack.

It came to lay at this point surrounded by moss and ferns and fallen sticks and leaves.

Even Stones have tales to tell. But who can understand them? We can only guess.
