In town for a University of Arizona event I gazed from the Marriott before dawn to remember painting “A” mountain with the Sophos service club a half century ago. The tradition continues.
The view to the southwest includes University Neighborhood, downtown Tucson skyscrapers, “A” Mountain (painted red, white and blue November 2010), Tucson Mountains.
Night Spring Sky, North America
Some nights I travel to the farthest reaches of the universe right from my backyard. Here is a guide to the spring night sky for those of you in the northern hemisphere. Even sunbathing we are time travelling, bathed in starlite over 8 minutes old. Time taken by sunlight to reach Earth = (150,000,000/3,00,000) seconds = 500 seconds = 8 minutes 20 seconds).
Our Winter Aconite started blooming around Valentines Day, February 14, 2023.
The following photograph is from the Apple IPhone 14 ProMax, raw format and perfected on the phone. The rest are from the Canon 5D Mark IV with the lens EF 100mm f/2.8 Macro USB.

As a spring ehemeral plant, its life cycle exploits the deciduous woodland canopy, flowering at the time of maximum sunlight reaching the forest floor, then completely dying back to its underground tuber after flowering.
All parts of the plant are poisonous when consumed by humans and other mammals because it contains cardiac glycosides.
The species name Eranthis hyemalis proclaims the early nature of its flowering both in the genus, “Eranthis” – “spring flower”, and species, “hyemalis” – winter flowering. The genus encompasses eight species, all early flowering winter aconite.
Imagine
Looking over my photographs from Mesa Verde National Park I find the Cliff Palace Round Tower to be a unique structure. You can see it in this shot taken from the Cliff Palace Loop overlook…..
It is easier to see here from this photograph taken from the Cliff Palace footpath from the mesa top.
Here is a closer view, with surrounding structures for context.
In 1941 the National Park Service commissioned noted photographer Ansel Adams to create a photo mural for the Department of the Interior Building in Washington, DC. The theme was to be nature as exemplified and protected in the U.S. National Parks. The project was halted because of World War II and never resumed.
The holdings of the National Archives Still Picture Branch include 226 photographs taken for this project, most of them signed and captioned by Adams (the following photograph had neither title or caption). Almost all are in the public domain, as is the following image. Adams was allowed free access to the ruins and had the luxury of time to stage perfect lighting.
Mary Elizabeth Jane Colter’s Desert View Watchtower (1932), on the Grand Canyon’s South Rim, was inspired in part by this round tower. She traveled throughout the southwest to find inspiration and authenticity for her buildings. The architecture of the ancestral Puebloan people of the Colorado Plateau served as her model. This particular tower was patterned after those found at Hovenweep and the Round Tower of Mesa Verde. Colter indicated that it was not a copy of any that she had seen, but rather modeled from several cliff dwellings.
The following photographs are my closest approximation to Ansel Adams composition. Taken during a public Ranger guided tour of Cliff Palace, I was standing next to the Square Tower (see my post “Square Tower as Viewed from the Kiva.”
The same image produced as Black and White.
The Round Tower is more compelling when viewed from below, in the following photographs.
Looking through these images I challange you, the reader, to compare the Round Tower with the right angles, straight walls of the other above ground structures and, then, the round Kivas in the grounds, essentially the Round Tower is an extension of the round kiva and sipapu toward the heavens.
Twenty million years ago a then nonexistent earth-bound human civilization could recognize none of the prominent stars of the constellation Scorpius (The Scorpion) as these, compared to our 4.6 billion year old star, lit up less than 12 million years ago. The brightest star, Alpha Scorpii AKA Antares, is a red giant destined to burst into a supernova bright as the full moon within two million years. Will the human race be around to witness it?
Such as it is, The Scorpion was traced out by the Babylonian astronomers around 8 BCE following even more ancient Sumerian traditions naming Alpha Scorpii “The Heart of the Scorpion.”
I first became aware of Antares March 2009 during a stay on Cocoa Beach. Setting the room clock to a 5 am alarm to view the sunrise. As I sat listening to the surf, Antares glowed dark red in the south. It is the reddish tint star in the following illustration.
Here is a photograph of Antares, the reddish dot in center, along with the 6 of the 18 Scorpius bright stars. For this shot a Canon EOS 5D Mark IV dlsr had mounted a Canon lens EF 70-300 f4-5.6L IS USM set to 70 mm focal length, 1600 ISO. Exposure was “bulb,” meaning when the shutter button is pressed and held the shutter remains open: for this exposure this was for approximately 10 seconds. The equipment was held steady on a Manfrotto BeFree Carbon Fiber tripod. As the Earth continued to turn, the resulting star images are smeared a bit.
Bracketing Antares, the Scorpion Heart are “The Arteries” Theta and Tau. About those Greek letters, these designate relative brightness of each star respective of the others in the constellation. “Alpha” the first letter of the Greek alphabet is the brightest. Here are the other letters listed, with the alphabetic order in brackets Beta(2), Delta(4), Pi(16), Sigma(18), Tau(19). Ancient Greek built on the traditions of the Mesopotamians (Babylonian and Sumerian) and were in turn used for modern stellar nomenclature, including the tracings of sky images, the constellations.
The position of a relatively minor star, Tau, near Antares elevates it to the important function of an artery. The stars themselves run against their brightness hierarchy placement: The star Delta Scorpii, after having been a stable 2.3 magnitude star, flared in July 2000 to 1.9 in a matter of weeks. It has since become a variable star fluctuating between 2.0 and 1.6. This means that at its brightest it is the second brightest star in Scorpius.
A small difference
Can you see the small difference between yesterday and today’s take on Devil’s Kitchen? Is the change and improvement, degradation or no difference? User Response Requested: respond in comments.
Here they are side by side.

Under the Spell of Treman Gorge
View shared by generations of newlyweds standing on a stone bridge across Enfield Creek. This is another version, taken a few years later and earlier in the season, Memorial Day morning.
Here is an image having me rethinking my conclusions. Here, I combined two images and worked hours to make many adjustments. The resulting Tiff is four times the filesize of the Raw file from yesterday.
Here they are side by side. In this case IMHO the extra disk space and time are worth it.

A tripod and Neutral Density filter
Winter 2020 I posted “Winter People Watching” featuring the Sony F828 and candid street photography.
What I love about this place, a unique feature, is the size and different vantage points making it possible to view the same place from different angles. November 2019, readers were shown “The Bend,” a place with Taughannock gorge makes a 90 degree turn, changing from a southeastern to an eastern flow. Here are photographs from spot overlooked by that post.
Here the camera faces away from the sun, the graduated neutral density filter allowing me to capture the cloudless blue sky, a little milky the way it is here February with a hint of spring.
This little one is studying the information placard with rapt attention, learning how the African continent, pushing against North America, across the eaons, formed the right angle fractures mirrored by this dramatic change in Taughannock Gorge. For the Big Bend photographs I was standing behind them, along the stream bed.
Here is a broader slice of that sky.
Can you see the tiny figures of hikers, dwarfed by the frozen cliff?
…and Gorge Cliffs
Purling of the water beneath this foot high waterfall was enhanced by reducing ISO to 100, tamping down the aperture to f/22 resulting in an shutter speed of 1/10th second. I set the graduated Neutral Density filter to shade the left side.
On the cliffs ahead is where the observation platform is cut into the rock. It has a great view of the waterfall, in some ways the experience of the falls is enhanced, compared to hiking the 3/4 mile path and standing below.
A marvelous forest grows on talus from the high gorge walls.
A sign on a disused pier warns waders to leave the creek bed. Ahead the gorge walls tower above the creek. Rocks dislodge and crash down unexpectedly, crushing foolish waders. It is appalling to see, in warmer months, people walking below those cliffs gathering the fallen rocks to make delicately balanced cairns.

Colored lights of our skies are a trigger for the imagination. The sky is a storybook to be written by the mind and passed along in language. The 3,000 observable stars and planets visible on any one moonless, clear night away from artificial lights draw on the human obsessional skill for pattern recognition.
Over millennia, stars along the path of the planets and sun through the sky held a special place for careful observers. Twelve patterns were imagined, each a named constellation. The word “constellation” means “to know from the stars.” Indeed, we can know much from the constellations. For example, it is winter in the northern hemisphere when the constellation “Cancer” (The Crab) is high in the night sky.
On the evening of January 20/21, 2019 the full moon climbed from the horizon (Click this link for the first post of this series “Total Lunar Eclipse of 2019…”) to a point high overhead were it appeared to float among the stars of Cancer, the crab. On the way, the disk darkened as its orbital path brought it into the earth’s shadow. The surrounding stars emerged from the darkening full moon glow. I captured the sight using a Canon dslr, the Canon EF 24 mm f/1.4L II USM lens mounted on a tripod by setting the ISO to 3200 to reduce the exposure to 1.3 second and placing the auto exposure area (a feature of the dslr/lens combination) away from the full moon.
Additionally, the moon is overexposed on the original image, for the following I used Photoshop to cut and paste the moon from the last photograph of this blog, reduced it to the approximate angular diameter of the moon and pasted it over the overexposed disk. There are better astrophotography images of this event, this image is mine to use and adequate for this purpose.
Cancer is difficult to trace, the constituent stars are all dim. Hint: click on any of the following photographs and a new page will open with a larger resolution image. What is striking in the following photograph are the number of apparently paired stars. Our sun is an exception, it is not part of a star system; even so, most of these pairings are line of sight, not physical star systems. For example, starting from the “red” moon there is a faint star, “Delta” of Cancer. Trace an imaginary line between the moon and Delta, in your mind move the line down and a little to the right to a pair of dim stars, “Nu” and “Gamma” of Cancer (left to right). The two are not a system, being 390 and 181 light years away. Each is a multiple star system in itself as is Delta. The three are on the back of Cancer, with two stars on the upper right being “Alpha” and “Beta”.
A most interesting object of this photograph, well worth the price of binoculars, is between Nu and Gamma and a little higher, towards the moon. It was what I saw the first time viewing this photograph: a cluster of stars called “The Beehive.” This was how I identified the location of the moon on the back of this crab.
For the following photograph I cut/pasted/enlarged a square with the (enhanced) Moon, Delta. Nu and Gamma, below, with the Beehive between them. See that the stars, though “fuzzy”, have colors. Delta is a orange giant, also known as the “Southern Donkey”. Gamma, the “Northern Donkey,” and NU are white. The back of the Crab holds a two donkeys eating from a manger, a Galactic Stellar Cluster name “The Beehive.” This night the moon joined the feast.
With binoculars (or telescope with a wide field eyepiece), the Beehive is a glorious spectacle of 1,000 gravitationally bound stars, a mixture of colors from blue to red. It was one of the first objects Galileo viewed through the telescope, picking out 40 stars. In later years it was here we found the first planets orbiting sun-like (i.e. having the characteristics of our yellow star) stars within a stellar cluster. In spite of being 600+ light years distant the Beehive was known since ancient times, being visible without a telescope in clear, dark skies.
A glorious moon at full totality is captured in the following two photographs. I used the dslr at 3200 ISO with the Canon EF 70-300mm f/4-5.6L lens at 300 mm. Setting the exposure area to the Moon, the exposure was 3.2 seconds.
In the first photograph, I especially enjoy the effect modeling of the shadows does to make the disk appear round. The field of view does not include Delta, Gamma, Nu or the Beehive. At this time I was not aware how close the Beehive was, or even that the Moon was in Cancer. The beauty of the moon floating among the stars is apparent.
