McMath-Pierce Solar Telescope – 1

The Exterior

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

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.

Inside the McMath–Pierce solar telescope is this keyed model of the observatory. Our docent for the morning tour stands alongside.

Kitt Peak from below

Rocks of a complex origin

“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

Survival

live on a Sky Island

Sky islands are isolated mountains surrounded by radically different lowland environments. The term originally referred to those found near the southern borders of the U.S. states of Arizona and New Mexico with the northern borders of the Mexican States of Chihuahua and Sonora such as the Dragoon Mountains featured in this post. The isolation has significant implications for these natural habitats. The American Southwest region began warming up between ∼20,000–10,000 years before the present-day and atmospheric temperatures increased substantially, resulting in the formation of vast deserts that isolated the sky islands.

This sycamore tree survives life in this ephemeral stream of an Arizona “Sky Island” by allowing entire trunks to die off during extended dry spells. The tree is an Arizona Sycamore (Platanus wrightii).

Cochise Spring

ancestral Apache land

Interstate 10 between Benson and Wilcox ascends through a field of enormous, eroded granite boulders. Off to the west are the Dragoon Mountains, otherwise known as “Cochise Stronghold.”

Informative sign at campsite

Starting from the campsite is the “Sky Islands Traverse” hiking trail, leading up into the mountains. I wandered from the trail to follow a dry streambed to this residual pool of water, the time being early spring, and this is what remained from the winter rains.

A single butterfly of the genus Anthocharis generally called “Orangetip” for the colorful upper wing tips. These exist throughout the world, here in Arizona they migrate across the desert, obtaining refuge and nourishment from “Sky Islands” such as the Dragoon Mountains

Waterfall Textures

Unrestrained chaos at the foot of Arizona’s highest waterfall

I received notice of IStock acceptance of select photographs from my last posting, “Wilderness Textures”, was accepted.  Click to view my IStock Portfolio, including  photographs from today’s posting included in the acceptance notice.

In this post I move up the Reavis Creek canyon from where the last posting, “Wilderness Textures”, was sited to the foot of Reavis Falls.  With the first photograph you look up at the falls from the head of the canyon carved by the creek over eons.  The rock wall, the canyon “head”, is thick with microorganisms, fungi, mosses.

Reavis Creek Water and Light – CLICK ME for more abstract photography.

In the foreground is a jumble of boulders, some washed down at flood time, spread wide at the bottom of the falls, piled to a jumbled height of 15 feet. 

Talus is the geological term for this formation.  Derived from the Latin word for slope (talutum) the definition, from the Oxford English Dictionary, is “A sloping mass of detritus lying at the base of a cliff or the like consisting of material fallen from its face.” 

 

The ankle bone is also called talus, from the French word for heel, I bring it up because climbing this chaotic, unstable jumble is a way to break your ankle.  The route to Reavis Falls, a climb up one side of Lime Mountain then down the other on a non-existent (lightly marked) trail, is rated difficult and impossible with a broken leg or ankle.  I was alone and very careful to check each rock for stability before putting my weight on it.

A climb of the talus pile was necessary to view the pool at the waterfall base, for this photograph.

A more artistic vertical format version, below, captured with the Canon EF 100mm “macro” lens.  All shots are using the Kodak DCS pro SLR-c (the “c” designated Canon lens compatibility) and a Manfrotto studio tripod with a hydrostatic ball head.  The horizontal format shot was captured with a Canon EF 50mm f/1.4 USM lens.   I prefer the vertical version, artistically, because the talus jumble is all but cropped out while the upper corner of the angular basalt boulder is left as an interesting focal point.  The boulder, not being in the spray, is in focus to contrast with the basalt wall behind the water.

I captured a series of shots from this precarious vantage point, working up from the pool to the brim of the waterfall.

My goals was a composite photo of the falls.  I have yet to succeed with this project.  Maybe I will give it one more shot in spite of having learned the hard lesson the best photographs are a single moment captured in a single frame.

I find in this series the vertical aspect is more artistic.  The water volume, of the falls, at this time of year offers only the finest of sprays with most of the basalt rock wall only moist.  The 100mm “macro” lens allowed me to include only the falling water with a bit of the moist wall for contrast.

In the following version I experimented with color, moving from the narrow range of hues, to more contrast.

Wilderness Textures

Abstract Beauty of the Superstition Wilderness of Arizona

These abstracts are some of my photographic output from four days and nights spent alone in the remote eastern Superstition Wilderness.  For the first three days I met not a soul, all these images were captured on a single afternoon spent in the canyon below Reavis Falls, a jumble of landslides, flood debris and boulders.  There is no trail.  The few people who enter the canyon must negotiate around boulders, crossing Reavis Creek many times.

My backpack kit included a full sized Manfrotto studio tripod with hydrostatic ball head.  The benefits more than outweighed the effort (I was a lot younger in 2008) when the Canon EF 100mm (macro) lens is mounted on a  Kodak dSLR body, allowing me to take crisp shots.  The tripod legs can be adjusted to precise positions for stability.

I can feel the bright afternoon desert spring sunshine in this photos.  It was after the spring floods, the flow of Reavis Creek and ample still but slow.  Gathering in pools over the rough stones of the creek bed, the water absolutely clear.

I held the shot over many minutes, capturing ever changing diffraction patterns.

We see in all these photos, not a homogenous blend of stones from a shared geology.  Reavis Creek washes over diverse geologies: volcanic, ancient igneous extrusions, sedimentary and metamorphic are jumbled together.

Cochise Dawn

ancestral Apache land

From 2004 through 2011 I visited Arizona every Autumn, October or November. As a University of Arizona Alumni Board member for the College of Agriculture and Life Sciences we had a meeting during “homecoming” and a fund raising event. I’d come early or stay later for getting acquainted with Arizona, more than was possible as an undergraduate. In 2007 I camped for several days Chiricahua National Monument of the remote south eastern corner of the state.

The park empties out this time of year, for some reason. The weather is perfection with clear skies, moderate daytime temperatures, cool nights. This time of year the Arizona White Oak acorns ripen and fall. The campground has aluminum picnic tables, the falling acorns made a loud plunks throughout the night. This would annoy some people. Me, it is a great memory.

The following two images are great memories from my first morning.

Rhyolite Moon
These formations hovered over the trail on my first morning. The rising full moon was an unplanned bonus.

I experimented this trip with a breakfast of granola with dried whole milk. It was delicious (for me) and got me out on the trail quickly. This first morning I clicked my hiking poles together to scare away bears as I walked in the pre-dawn dark. The preparation and extra effort paid off with this photograph.

I met one hiker who was a harbor pilot from Hamburg, Germany. He came just to view a particular rock formation that was, literally, the rubber bath duck. It is several miles to the site, a moderate hike with significant elevation gain. He took his snapshot with a little camera and was on his way.

The following is my masterpiece from the trip. Imaging the effect of seeing this image on settlers. That same first day I turned a corner and there this was…it took a few minutes to comprehend what I saw, it was so incredible and, for me, unexpected. It first, the only perception is a huge rock dome of rough rock, then, slowly, the image of a native American profile forms in the mind.

During the session for Cochise Dawn I turned the camera for the view northwest and did a self portrait. In the distance are the Galiuro Mountains and Wilderness. Tucked alongside is the Aravaipa Canyon Wilderness, hosting one of the few perennial streams of Arizona.
