In my experience to come across the denuded ribs of an expired Saguaro cactus is to find a single one among thousands of flourishing, many-armed giants. Fourteen years ago, when this photograph was taken March 2008, a drought hung over Arizona since 1994, fourteen years. One documented effect of twenty-eight drought years is fewer young saguaro now survive into adulthood, the number of standing specimens is slowly decreasing.
On the slopes of Peter’s Mesa, Superstition Wilderness, Arizona
Here we are below the rim of Peter’s Mesa of the Superstition Wilderness. Blue Dicks flourish as the feet of the long-expired giant, the wildflowers grow from corms long used as food by Native Americans. Behind is a large stand of Prickly Pear cactus whose fruit, called tunas, is another food source.

I was a member of an expedition to Peter’s Mesa March 2008, a place central to Superstition Wilderness treasure legends. This is a sunset view, looking south, southwest. Light raking across the desolation and Miner’s Needle creates a fascinating spectacle. Ancient volcanism, apparent throughout the Superstition Wilderness, is here seen in the texture, form and type of rock as well as the mineral deposits. Miner’s Needle, like Weaver’s Needle (not seen in this view), are eroded volcanic summits. Look closely for the “eye” of Miner’s Needle, easier seen in the cropped heading photograph. To this day, hopeful prospectors search for gold nuggets.
There is one form of volcanism present today as an eerie rumble or hiss, similar to an enormous distant jet engine heard now and then during our two days on the mesa, louder and closer than an overhead plane could produce. The view includes many notable Sonoran Desert plants. Many young Saguaro cactus are in the form of green poles. Catching the dramatic light, on the ridge is a tall single flower of an Agave, known as the “Century Plant” it flowers once in a long life and dies.
Peters Mesa is named after “Old Pete” Gottfried Petrasch, father of Hermann and Rhiney Petrasch. Old Pete worked for Jim Bark for awhile in the 1890s doing odd jobs. Irregular employment gave Pete and Sons time to s searched for the Lost Dutchman Mine in the years following the death of the source of the legend, the “Dutchman” Jacob Waltz. The Petrasches were one of the first groups to search for the mine, and gold in general. They covered almost the entire Superstition range in their combined searches.

On our first day on the mesa, we came across the remains of one of these camps, on the top of Squaw Canyon, a deplorable junk pile discarded by searchers, presumably disappointed, too lazy to cart it out. That March, we were lucky to find the remnants of winter rains in the form of a meager trickle at the bottom of a shallow draw off Peter’s Mesa trail up from La Barge canyon. We had a good time of it until the trip was cut short by a storm front and torrential rains. We were back in Apache Junction before they hit.
Here is a series of photographs of the January 31, 2018 SpaceX launch of a Falcon9 bearing a Govsat1 (aka SES-16) satellite for Luxembourg. The re-used Falcon 9 was in expendable mode. The photographs, taken from Cocoa Beach, Florida show the rocket rising above the city and port of Cape Canaveral, through cumulous clouds and into space.
There are the unedited “jpeg” files from the series. I need to crop out the dust spots and such.
In the early morning hours of Sunday, September 10, 2017 as Hurricane Irma approached the Florida Keys, I cannot sleep, worried about family members north of Miami and in Daytona Beach. To pass the time, I returned to the golden hours of March 4, 2017 evening. On vacation, Pam and I walked Cocoa Beach starting from Lori Wilson Park, headed north.
The light was perfect when I decided to switch to Raw-Jpeg mode, feeling the extra space was worth it. I don’t know why I don’t shoot Raw 100% of the time, as always, in retrospect, I regret using jpeg only. The camera was the Sony Alpha 700 dslr with a DT 18-200mm f3.5-6.3 lens purchased 2008 after an expedition to the Superstition Wilderness.
After capturing a wedding photo shoot and surfers there was this set of two Kite Skaters going at least 20 miles an hour. The Sony Alpha was quick enough to capture some of the action in raw mode, I am not satisfied with the sharpness of the images as the lens was not fast enough.
We had never watched kite skaters before and were prepared to understand the vision from watching distant kite surfers out beyond the breakers. North winds are the best for any type of kiting on Cocoa Beach and, that day, the wind was northeast. These riders zipped by in less than a minute. The sport is low key, it does not exist on Wikipedia. Image that. These two are having a fantastic time and stayed upright, going on and on and on down the miles long beach.

These views within the McMath–Pierce solar telescope enclosure were captured during a guided tour of the instrument, April 20, 2005. By way of orientation, the observation room we visited is near the location labeled “4” on the model of the following photograph or the “Observation Room” of the drawing.
We learned each of the sets of mirrors is considered a separate telescope. The first step in designing the new solar telescope was to determine the optimal image scale. Working on the spectra of the solar granules, on the physical structure of the sunspots and their associated magnetic fields, requires a considerable image size. Past experience has shown that the optimal image of the sun should be approximately 0.91 meters. The highlight of our visit to the Main Observation room was meeting with the technician operating the recently developed low-cost adaptive optics system.
Tip-tilt correction and low order wavefront correction is available with a number of portable optical benches. These are primarily used with the Main spectrograph and the Solar Stellar spectrograph on the Main telescope, but due to their compact mounting they could be used with other telescopes and instruments in the facility.
This configuration uses a rapidly deformable mirror to correct distortions introduced by the turbulent atmosphere. Using sensors to measure the degree of image distortion, the adaptive optics system adjusts the shape of the mirror accordingly and converts a blurred image into a clear one. The following image demonstrates the correction. “Low-cost” = $25,000 in 2003 US dollars. Under references is a link to a full description of the device by the creator.

A main area of study in the observatory is the structure of sunspots, which are relatively cold, dark spots on the surface of the Sun created by intense magnetic activity.
Some of the most important discoveries made at McMath-Pierce include the detection of water vapor in the Sun, the measurement of kilogauss magnetic fields (thousands of times stronger than those on Earth) outside sunspots and the detection of a natural maser (like a laser, but with a microwave instead of visible light) in the Martian atmosphere.
Over the years and technological advances, the National Solar Observatory has moved its headquarters from Tucson to Boulder, Colorado. The organization abandoned its solar telescopes at Kitt Peak and in New Mexico for a larger instrument in Hawaii, the Daniel K. Inouye Solar Telescope on the island of Maui, which began operating in 1919.
These views within the McMath–Pierce solar telescope enclosure were captured during a guided tour of the instrument, April 20, 2005. By way of orientation, think of yourself at the location labeled “4” on this model. This is the only large telescope where humans can view the interior and visually experience the light paths “bouncing” between the mirrors.
McMath–Pierce solar telescope has three heliostats mounted on a 110-foot tower adjacent to a slanted enclosure. The 2.03-meter heliostat feeds a 1.61-meter primary mirror, there are 1.07-meter and 0.91-meter primary mirrors fed by a pair of 0.81-meter heliostats. Here we are inside the slanted enclosure, looking up the shaft to the tower mounted heliostats, readily identified as the three circles, the largest at center (3.51 feet in diameter). The smaller (2.66 feet) heliostats named “East” (on left) and “West.”
Built in 1962, the building was designed by American architect Myron Goldsmith and Bangladeshi-American structural engineer Fazlur Rahman Khan. It was the largest solar telescope and the largest unobstructed aperture telescope in the world. It is named after the astronomers Robert Raynolds McMath and Keith Pierce. Painted white to reflect sunlight to reduce heat accumulation, the enclosure is water cooled to prevent convection currents through the column of air within the slanted enclosure, keeping the air as still as possible along the light path between the mirrors.
In the three photographs following, we face the underground portion of the slanted shaft and (what looks to be) the 0.91 meter (2.99 feet) primary concave mirror. I say that because in some of the photographs a beam of light, to the left of the mirror, can be seen travelling further underground, presumably to the largest primary mirror. As there is only one such light beam, I conclude the west heliostat is inactive.
Here we looking up the slanted enclosure. Look carefully at the first photograph, below, to see reflections on the glass partition. The observation platform was separated from the light paths to maintain the stillness of the air column. The two mirrors of the first photograph are the third mirror, reflecting concentrated sunlight from the 0.91 and 1.61-meter primary mirrors into the observatory rooms. The mirror for the 1.07-meter primary is out of sight in foreground, I believe this set of three mirrors (West heliostats, primary and third) was out of service.
The second photograph, on right, is a close up of the third mirror for the largest primary. A foreshortened, perfectly round light disk is clearly visible.
Here we are inside the slanted enclosure, facing the underground portion of the slanted shaft and (what looks to be) the 0.91-meter primary concave mirror. In the lower right corner is the reverse side of the third mirror for the largest primary mirror, the 1.61-meter.

These views of the McMath–Pierce solar telescope enclosure are the preliminary to a guided tour of the instrument, April 20, 2005.
On the tower are three heliostats, plane (flat) mirrors mounted on computer-controlled platforms to follow the sun across the sky to direct sunlight to primary mirrors underground, beneath the base of the slanted shaft

“When George J. Roskruge created the official map of Pima County in 1893, he named the range after James Quinlin, who had opened a stagecoach station in the nearby town of Quinlin in 1884.” — Wikipedia article for “Quinlan Mountains.”
Kitt Peak is the highest point of the Quinlan Mountains, one of a series of ranges starting near the border with Mexico, the Baboquivari Mountains. Pan Tak pass separates Coyote Mountains from the Quinlans. Farther north there is even the Roskruge Mountains and a range named for a silver mine, the Silver Bells. Roskruge originally named “Kit’s Peak” for his sister, Phillippa, married to William F. Kitt. The peak was renamed to Kitt Peak William’s request.
Here we see a dramatic view of Quinlan Ridge with Kitt Peak observatories, taken from the access road Arizona Routh 386. The instruments I recognize are, from left to right, McMath-Pierce Solar Telescope (second in line) and, on the end, Mayall Telescope.
And more views as I progressed toward the top.

The dramatic peaks are hypothesized to be igneous intrusions into metamorphic rock, these are called “Sky Islands” for the environments supported on them, radically different from surrounding lowlands. Kitt Peak is known for the stands of Manzanita Bushes

The Contreras fire threatening Kitt Peak last month brought to mind a spring visit of mine to the National Observatory.
From downtown Tucson get onto Interstate 10, heading “east” toward El Paso. East in quotations as the road only turns east after the fork for Interstate 19, headed south past San Xavier del Bac mission and Nogales at the Mexican border. A few miles down I19, well before the mission, a turnoff for Arizona route 86, a road you’ll follow the better part of 36 miles, passing the Tucson Mountains on the right. Most days, the Mayall Telescope of Kitt Peak shines bright white ahead, as it did the right after dawn on Wednesday, April 20, 2005.
At some point R86 enters the 4,453.307 square mile extent Tohono O’odham Nation Reservation, you pass the town Three Points where Arizona route 286 heads south to Sasabe and the Mexican border. The next turn south is the Kitt Peak access road, Arizona route 386. On that Wednesday I was so early the gate to the peak was locked, so I pulled off the road and waited. It is a lonely place on the route for migrants from Mexico. I wandered off the road, into a wash (dry, sandy stream bed), to relieve myself, where junk from migrants was scattered around. Back in the car a helicopter approached with a black SUV. A big guy got out, walking by into the wash: the border patrol.
Here is a photograph from that day of Baboquivari Peak taken from Kitt Peak’
Baboquivari Peak is the most sacred place to the Tohono O’odham people. It is the center of the Tohono O’odham cosmology and the home of the creator, I’itoi. According to tribal legend, he resides in a cave below the base of the mountain. This mountain is regarded by the O’odham nation as the navel of the world – a place where the earth opened, and the people emerged after the great flood. Baboquivari Peak is also sometimes referred to as I’Itoi Mountain. In the native O’odham language, it is referred to as Waw Kiwulik, meaning “narrow about the middle”. The O’odham people believe that he watches over their people to this day. — Wikipedia
Baboquivari Peak was mentioned in the journals of Jesuit missionary Padre Kino, who made many expeditions into this region of the Sonoran Desert, beginning in 1699, establishing Spanish Missions in the area. — Wikipedia
Kitt Peak is in the sacred precinct of Baboquivari, the land just below the peak is the “Gardens of the Sacred Tohono O’odham Spirit I’itoi.” The month of my visit, the O’odham nation brought legal suit against Kitt Peak to halt construction of new telescopes in the garden. The issue was settled out of court.

Here is a photograph from our day touring the Glens of Antrim. While making our way up the coast to Torr Head a group of stone walls resolved into ruins. A cluster of cottages on grassy slopes above the Irish sea above Loughan Bay. This is the townland of Loughan. Along the road are wonderful signs providing in handsome carved letters the place name in english and gaelic. Here a signed only provided a gaelic name: “Loughan an Lochan”…near enough to meaning “Loughan Bay” in English. The bay is a shallow scallop shaped indentation of the coast, a margin of narrow sand strand.
Ruins are spread across the slope. Immediately before the views are traces of a foundation above the grass. Beyond the top of a gable, an entire gable to the left. On the far ridge, just visible, is an entire structure with doorways, gables, walls.
Across the Irish Sea, 13 miles distant, is the Mull of Kintyre. In faint outline, rising above the horizon, find the highlands of Islay more than 30 miles. Both are tips of peninsulas jutting from Scotland.
