Teaching Elementary School Students Geology in Sabino Canyon (January 2019)
Sabino Canyon Volunteer Naturalists (SCVN) stopped offering their Elementary School Nature program in March of 2020 because of the pandemic. Since teachers are no longer able to bring their students to the canyon, SCVN has begun creating a series of videos, Sabino Canyon, The Canyon Classroom, and placed them on YouTube.
Several videos have been created to date. The most recent one is Harvester Ants.

She cares about the environment She questions the conditions She seeks knowledge She answers the questions She is a problem solver She accepts the facts She shares her world She sees limitless horizons She lives in the moment She is a naturalist.
The Sabino Canyon Volunteer Naturalists (SCVN) have been preparing a new kit for Elementary School Program, which will be on pollinators. I was asked to provide some photos of pollinators. One of the photos first appeared on this blog in a grunge art piece I did in September of 2015, which I mistakenly identified as a viceroy.
One of the Pollinators kit developers is SCVN member Fred Heath, whom we consider our butterfly expert. Fred let me know that I had misidentified the butterfly —
“The orange and black butterfly is a Queen and not a Viceroy.
As you probably know, the Viceroy is a mimic of the Monarch and Queen.
In the east where there are more Monarchs than Queens,
the Viceroy is a brighter orange. Out west and in the south where there are more
Queens than Monarchs the Viceroy is more of a burnt orange like the Queen.
The one quick way to distinguish between the Queen and the Viceroy,
that that the Viceroy has a black median band,
which goes across the hindwing and the Queen doesn’t have that band.
This mistake is made a lot. There was a billboard that advertised Mexico and the Monarchs,
but the butterfly in the billboard is a Viceroy.
When I google Viceroy, the first picture they show is a Monarch.”

October 7th, SCVN naturalist David Dean conducted an advanced training tour of the Biomes of the Santa Catalina Mountains.
We began the tour by meeting at the McDonald’s at Catalina Highway where David provided an overview of the biomes of the Catalinas. Before starting the car caravan up Catalina Highway, David covered the lower biomes, the Saguaro-Palo Verde (100′ – 4,000′), which includes the dominant cacti and legume trees; the Desert Grassland (3,800″ – 5,000′) with grasses, succulents & shrubs being dominant.
At about the 5.5-mile marker, we pulled off at Molino Basin where David lead a discussion on the Oak – Grassland biome (4,000′ – 5,600′) and Oak Woodland (5,000′ – 6,000′) biome. Here he used posters and the natural taurine to cover; Trees: Emory Oak, Mexican Blue Oak, Silverleaf Oak, Arizona White Oak, Alligator Juniper, Western Soapberry, Border Pinyon Pine: Shrubs: Mountain Yucca, Soap-Tree Yucca, Shindagger Agave, Sotol, Golden-flowered Agave, Beargrass; Grasses: AZ Panic Grass, Blue Grama, Sideoats Grama, Cane beard grass, Spidergrass, Bush Muhly, Bull Grass, Lehmann Lovegrass; Oak – Grassland: Oaks & Junipers, Chihuahua Pine, Buckbrush, Golden-flowered Agave, Mt. Yucca.
Our next stop was along the highway near Bear Creek to discuss the Riparian Corridor (Not a biome) where we found AZ Sycamore, AZ Walnut, Gooding Willow, Fremont Cottonwood, Velvet Ash, AZ Cypress, AZ Alder.
At the approximately the 5,400″ elevation we stopped at the Middle Bear Picnic/Green Mountain Trail Head to learn about Pine-Oak Woodland biome where the dominant plants are AZ Pine, Chihuahua Pine Silverleaf Oak, AZ White Oak, Emory Oak, Black Cherry, Alligator Juniper.
Next, we stopped at Windy Point Vesta(6,500′), a popular place for tourists driving up the scenic Catalina Highway. At this location, David talked about the Chaparral biome, which includes Silver Oak, AZ Madrone, Border Pinyon Pine, Alligator Juniper, Manzanita, Golden-flowered Agave, Beargrass, and Buckbrush.
At the 19.3-mile highway marker (7,825′), David leads a discussion on the Pine Forest biome where the dominant plants are AZ Pine, SW White Pine, Ponderosa Pine and occasional Douglas-Fir.
As you can see, David used live plant specimens on his posters.
Ever wonder how Mt. Lemmon got its name? The highest point in the Santa Catalina Mountains (9,152′) was named after Sara Plummer Lemmon, a respected botanist from New Gloucester, Maine, who arrived in Arizona after living in coastal California. Her Arizona fate was sealed when she attended a botany lecture in 1876 led by her future husband, John Gill Lemmon, and the whirlwind romance was on. After four years of courtship, the two wed and worked together cataloging the flora of the West, which would lead them to the Coronado National Forest in the southern section of what was then the Arizona Territory.
A discussion on the last biome in our tour, Mixed Conifer Forest (Above 8,000′) took place at Bear Wallow (8,100). Here David illustrated the common plants in the Mixed Conifer Forest: Ponderosa Pine, AZ Pine, SW White Pine, Douglas-Fir, White Fir, Quaking Aspen; Silverleaf, Netleaf, and Gambel Oaks; Rocky Mountain, Big Tooth, and Box Elder Maples.
In hindsight, I wish I had done both photography and video of the biomes tour. Near the end of the tour, I did think about doing a video clip, which is what follows.

Hikers in a New Aspen Grove Up from Marshall Gulch On Mt. Lemmon — Image by kenne
In 2003 the Aspen Fire destroyed many homes in Summerheaven and thousands of acres on Mt. Lemmon. Last Friday the Sabino Canyon Volunteer Naturalists led hike was on the Aspen Loop that goes through some of the areas destroyed, now recovered by new aspen and pine groves.
A precursor to the Aspen Fire was the Bollock Fire, 2002 in the eastern part of the Catalinas. Parts of the area burned in 2002 is now experiencing the Burro Fire that started Friday and has now consumed 9,000 acres. The Burro Fire is one of a half-dozen wildfires in the Coronado National Forest. Did I say it is hot and very dry in southeastern Arizona?

THE MUSHROOM HUNTERS
Science, as you know, my little one, is the study of the nature and behaviour of the universe. It’s based on observation, on experiment, and measurement, and the formulation of laws to describe the facts revealed.
In the old times, they say, the men came already fitted with brains designed to follow flesh-beasts at a run, to hurdle blindly into the unknown, and then to find their way back home when lost with a slain antelope to carry between them. Or, on bad hunting days, nothing.
The women, who did not need to run down prey, had brains that spotted landmarks and made paths between them left at the thorn bush and across the scree and look down in the bole of the half-fallen tree, because sometimes there are mushrooms.
Before the flint club, or flint butcher’s tools, The first tool of all was a sling for the baby to keep our hands free and something to put the berries and the mushrooms in, the roots and the good leaves, the seeds and the crawlers. Then a flint pestle to smash, to crush, to grind or break.
And sometimes men chased the beasts into the deep woods, and never came back.
Some mushrooms will kill you, while some will show you gods and some will feed the hunger in our bellies. Identify. Others will kill us if we eat them raw, and kill us again if we cook them once, but if we boil them up in spring water, and pour the water away, and then boil them once more, and pour the water away, only then can we eat them safely. Observe.
Observe childbirth, measure the swell of bellies and the shape of breasts, and through experience discover how to bring babies safely into the world.
Observe everything.
And the mushroom hunters walk the ways they walk and watch the world, and see what they observe. And some of them would thrive and lick their lips, While others clutched their stomachs and expired. So laws are made and handed down on what is safe. Formulate.
The tools we make to build our lives: our clothes, our food, our path home… all these things we base on observation, on experiment, on measurement, on truth.
And science, you remember, is the study of the nature and behaviour of the universe, based on observation, experiment, and measurement, and the formulation of laws to describe these facts.
The race continues. An early scientist drew beasts upon the walls of caves to show her children, now all fat on mushrooms and on berries, what would be safe to hunt.
The men go running on after beasts.
The scientists walk more slowly, over to the brow of the hill and down to the water’s edge and past the place where the red clay runs. They are carrying their babies in the slings they made, freeing their hands to pick the mushrooms.
“The morning is still and perfectly clear…
How cool and crystalline the air!
In a few hours the great plain
will be almost like a fiery furnace
under the rays of the summer sun,
but now it is chilly. And in a few hours
there will be rings and bands with scarves
of heat set wavering across the waste upon
the opalescent wings of the mirage;
but now the air is so clear that one can see
the breaks in the rocky face of the mountain range,
though it is fully twenty miles away…”
On Thursday of this past week, Sabino Canyon Volunteer Naturalists were teaching two first grade classes about predator and prey in a program we call “Now You See It.” My responsibility for the month of April is to coordinate the Thursday schedule with the teachers. Once the children are in the canyon, my job is one of “managing by walking around.”
While in the riparian area near the creek and dam I could hear a nearby cooper’s hawk. Following the sound, I spotted him on a dead limb high above the creek where he had caught a small bird. What a “real time” example of predator and prey for the day’s lesson. What follows are images and a video of the encounter, which I shared with the children.

Predator And Prey — Cooper’s Hawk
The varying modes of flight exhibited by our diurnal birds of prey have always been to me a subject of great interest, especially as by means of them I have found myself enabled to distinguish one species from another, to the farthest extent of my power of vision.
SCVN Friday Hike on Esperero Trail (February 17, 2017) — Image by kenne
A mostly cloudy morning with sunlight breaking through over the Tucson basin as we begin our hike into the mountains heading into rattlesnake canyon, first hiking up, then down through three canyons creating a breathtaking rollercoaster hike.
Starting as on group, the pace soon divides us into three groups as hikers settle in on their own pace created by elevation changes and stopping to shed layers of clothing as the temperatures increase and the sun begins to break through deep blue cracks in the desert sky.
The SCVN Friday Hike last week was to Hutch’s Pool. This is a hike that is about eight miles from Tram Stop 9, which saves another eight miles by not hiking from the Sabino Canyon Visitor Center. About twenty hikers were hiking the Sabino Canyon Trail to the intersection of West Fork and East Fork trails. The East Fork goes to Sycamore Canyon, the West Fork to Hutch’s Pool. There are two water crossing to Hutch’s Pool, the first providing the lesser challenges of the two. Still, on this day the water was swift, just below the knee and ice cold.
Because of recent rains and snowmelt on Mt. Lemmon, the water flow was much higher than normal causing most hikers to turn back or take the East Fork to Sycamore Canyon. Five hikers decided to go on to Hutch’s Pool. The images and video or of their return crossing at the creek near where the Fork trail connects to the Sabino Canyon Trail.

“Mountains should be climbed with as little effort as possible and without desire. The reality of your own nature should determine the speed. If you become restless, speed up. If you become winded, slow down. You climb the mountain in an equilibrium between restlessness and exhaustion. Then, when you’re no longer thinking ahead, each footstep isn’t just a means to an end but a unique event in itself. This leaf has jagged edges. This rock looks loose. To live only for some future goal is shallow. It’s the sides of the mountain which sustain life, not the top. Here’s where things grow.
But of course, without the top, you can’t have any sides. It’s the top that defines the sides. So on we go—we have a long way—no hurry—just one step after the next—with a little Chautauqua for entertainment. Mental reflection is so much more interesting than TV it’s a shame more people don’t switch over to it. They probably think what they hear is unimportant, but it never is.”
