Day 1 – The Geology Wall
Unique in all of Tucson, if not the world, is Tohono Chul’s Geology Wall exhibit. The idea of founder Richard Wilson, a geology professor with the University of Arizona, and built by geologist Doug Shakel and Toby Wright, the 55 foot long, semi-circular wall consists of several hundred rock specimens that represent the more than two dozen geologic formations that comprise the 9,000-foot Santa Catalina Mountains, visible just over the top of the wall itself. As you proceed along the Wall from left to right, you are walking through nearly two billion years of the Earth’s history! In general, the rocks of the Catalinas (and the Wall) become younger and younger as you proceed southward. Thus Tucson is built on the youngest rocks, displayed on the far right. The oldest are displayed on the far left and would be found north of Tucson near the town of Oracle.

Kartchner Caverns
In November 1974, Gary Tenen and Randy Tufts were exploring the limestone hills at the eastern base of the Whetstone Mountains. They were looking “for a cave no one had ever found” and found it. The two kept the cave a secret until February 1978 when they told the property owners, James and Lois Kartchner, about their awesome discovery. Since unprotected caves can be seriously damaged by unregulated use, they knew the cave had to be protected. Tenen and Tufts spent several years looking into the possibility of developing the cave themselves. Some members of the Kartchner family lived in Tucson and were very impressed with the development and operation of Catalina State Park by Arizona State Parks. They decided to approach State Parks to see if the agency was interested in acquiring this outstanding resource.

James Burton
Lavender Pit
“More than a quarter billion (with a “b”!) tons of rock were removed from the Lavender Pit, including almost the whole town of Lowell, Arizona. The pit, even though it is lavender, is named for Harrison Lavender, the mining engineer who conceived the idea of the open-pit mine.”
More
James began using a film camera when he was eight and began doing his own darkroom work as a child. Later, in college in Tempe, Arizona, he fell deeply in love with the American Southwest. His career as a scientist and archaeologist took him across four continents, but Arizona remained, by far, his favorite place on the planet. When James retired in 2015, he returned to Arizona and found time to use a camera again, together with a computer. This has greatly expanded his ability to create images that express how he experiences the desert.

Janet Windsor
Lavender Pit
“Copper mines are very controversial in Arizona. While they bring in much needed revenue and jobs, they do not leave the landscape untouched. We no longer dig deep into the mountains; we blast them apart, leaving scars upon the land in pursuit of that prized commodity.
More
But, if you look closely, those scars are indeed beautiful, revealing all the layers that lie beneath and each pit is different. The Lavender Pit in Bisbee is aptly named for its beautiful purple layers. And these layers became a quilt.”
I use the desert around me to inspire my works in fabric. The endless variation of color and form lends itself to abstraction in fiber. With this collection, I have branched out in new directions. I have used hand dyeing, embroidery, applique; all of which have been used sparingly, if at all, in my previous work. I have used new materials including wool, tie-dyed velvet and linen, embroidery floss, beads, the better to reveal that hidden beauty inside those dark twisted trees.

Ray Mine Montage 10
“My aerial photographs were inspired by the aerial work of Emmett Gowin, which I first encountered when he began shooting Mt. St. Helen’s in the late 80’s, and his later work of mines and bomb sites in his book Changing the Earth. The impetus to actually begin taking aerial photographs came
More
about when my son got his pilot’s license in high school in 2001. I began flying with him over Southern Arizona and naturally, I began to photograph from the plane.
We flew over mines and as I looked at them, I understood why Emmett had photographed them. The shapes and colors were amazing, like abstract paintings thrown onto the earth. From the very start, I made the decision not to follow what many other photographers had done with mines and make documentary photos about the destruction of nature. I felt that had been done and besides it seemed too obvious. Of course, these mines were a blight upon the earth, all you had to do was look at them to see that, but they also contained a terrible sort of beauty. They were like road maps of our way of life, the results of the decisions we had made to extract these minerals for our steel and copper, and in their own way, they were huge abstract earth sculptures, the sculpture of our time displayed upon the canvas of the earth.
I made digital scans from the film I shot and once the work was in digital format I realized I could piece these together. I saw no reason I could not work with them like a puzzle, pieces of earth, of shape and color, lines of roads and road cuts, the circles of the open pits and holding ponds. The mines had certainly paid no attention to the earth so I saw no reason to pay attention to factual recording of the mines, if they could move the earth around so could I. The mine photographs are montaged, pieced together from various mines and sections of desert, made into a composition the same way an abstract painter or a mapmaker might work with shapes of color and form.”
William Lesch was born in Indianapolis, Indiana and grew up in the Midwest. His childhood summers were spent on Lake Wawasee in Northern Indiana and it was at Wawasee that he began forming an intimacy with the natural world. Lesch discovered photography and met his future wife, his two life-long loves, in the same year at the age of 21. He took photography as an elective course while in a pre-med program. Lesch had found his calling; he dropped out of pre-med and switched to art the following semester. Lesch earned a BFA in photography from the University of Arizona in 1976. He was the first Staff Photographer at the Center for Creative Photography from 1976-78. It was at this time that he began work on many of his signature series: his first time exposures of clouds, his early color work in the desert, and the beginning of his time-lapse light painting series. William Lesch still resides in Tucson, Arizona. He lives and works in an adobe house and darkroom that he built himself, by hand, making the adobe in his backyard. Lesch has always felt that life and art are about weaving together complex threads, be those threads of color, light and time, or experiences and skills.

Bisbee Copper Mine
“Bisbee is a very quaint little town with an open pit copper mine. The shaft was used for taking miners down into the depths of the earth. The open pit mine, with its many terraces, is a very colorful sight due to the different soil colors. It was mined mainly for the exceptional quality of copper found there,

but it also produced gold, silver, lead, zinc and manganese.”
Fiona was born in Nairobi, Kenya, and lived there until 1965, when she moved to England and married. In 1969, she moved to Canada and lived there until 1974 before making Tucson her permanent home. She has been interested in art, mainly watercolors and drawing, all her life, but only started painting seriously in 1979. She is a signature member of the Southern Arizona Watercolor Guild, the Montana Watercolor Society, Arizona Aqueous, and a member of the Tubac Center of the Arts. Her paintings can be found in collections in the U.S., Canada, England, and South Africa, and have been accepted in numerous juried national and local art exhibitions.

Cochise Head
“This painting shows the mountain that resembles the upward facing head of Cochise in the Chiricahua Mountains. The way the peaks settle into facial features in a way that looks both intentional and natural was strangely beautiful to me.”

Carson was born in the Midwest and moved to Arizona as an adult. His artwork is based off his travels around the state and the western part of the country and uses planar analysis to depict these landscapes as a complex puzzle of interlocking shapes and color. His aim is retain the sublime feel of the original location while visually exploring the geometry of spatial relationships.
Carson takes a vintage Polaroid 600 camera on his road trips to capture iconic American landscapes through a nostalgic filter. This imbues the images with a washed out color palette that evokes memory of the landscape as a moment of singular discovery. He then creates watercolor studies in his sketchbook of the photographs, choosing select compositions to paint larger scale using acrylic on canvas or board.

Secret Waterfall
“For almost 5,000 years copper was the only metal known to man. Only 12% of the estimated 5.7 trillion tons of worldwide reserves have been

mined since the time of its discovery 10,000 years ago, but, because it is highly recyclable, nearly all of that is still in use.
Copper and water are inseparable. The mining of copper requires enormous quantities of water, and Arizona has very little water but a lot of copper. Is it possible to balance the need for copper and the need for water? In the consumption of copper, we are all complicit – it is in our cars, our cell phones (recycling 1 million cell phones yields 32,000+ pounds of copper!), our computers, our houses – it is in our very bones. Can we reconcile our need for this mineral with the myriad long-reaching adverse consequences of its extraction?”

cooled lava looks as though it just happened yesterday. The lava flows are young, as in 40,000 years ago. Once molten and unapproachable, they are still a forbidding place to go if you’re a human.
This piece was about getting into the detail of the rock and being true to its nature. When you get into the details, it’s more like working on an abstract piece. Nature’s abstraction pulls you into the details.”

“These works are part of an extended series of aerial photographs of copper mines in Southern Arizona that I have been working on for the past fifteen years.

The photographs were all taken between 2001 and 2006 and printed in 2018. My current prints of these works are made on copper panels coated with white gesso paint that has been aged and dried to expose the copper sheet under the photograph through a veined network of drying cracks in the paint surface. This is done for many reasons, including the visual effect of actual copper veins in a photograph of copper mines. I am interested in the abstract beauty of the mines from the air and how this works with our natural feelings of dismay with how the earth has been gouged and transformed in the process of digging out the copper. We all use copper, from our phones to our computers to the wiring in our homes but the history of our mining of copper is replete with ruined landscapes and blighted areas left after the mining has stopped. I feel it is important to consider these places we have created on the earth, to me they feel like earth paintings that reflect our civilization, both its chaos and its beauty.”
