All outings are led or co-led by Clifford Blizard, Ph.D. Dr. Blizard holds degrees in environmental science and geology, as well as an Elementary teaching credential from the American Montessori Society. He has taught elementary and middle school as well as courses at the community college and university levels. He has also offered adult education programs in sense of place, and has led numerous outings for students ages 5 through 85. He is versed in, and enthusiastic about, all facets of natural history, including ecology, geology, entomology, botany, etc. He is also fascinated by cultural history and prehistory, and intrigued by landscape and story.
If there is some other facet of local natural or cultural history that particularly interests you, just let Clifford know, and he will be glad to tailor a program to fit your topic interests. There will be an additional one-time requested donation of $30 for developing a specially-designed program.
Rockin’ with Lichens (K-12)
This program will meet at Hutcheson Ferry Park on Hutcheson Ferry Road, in Chattahoochee Hills (directions to be provided). We will spend three hours exploring the park and learning about lichens and viewing other cultural and natural features at the park. The park includes a rock outcrop with old cedar trees, the remains of a rock quarry, woods, fields, and a lake.
Reading the River: An Introduction to Adopt-a-Stream (grades 3 and up)
This program will meet at a trailhead into Cochran Mill Park on Cochran Mill Road in Chattahoochee Hills (directions to be provided). We will spend three hours along Bear Creek, learning about chemical and biological stream monitoring, assessing the stream’s water quality and looking for “bugs” living there. This outing is intended as an introduction to Georgia’s Adopt-a-Stream program; should there be sufficient interest, Dr. Blizard plans to form a local group that would meet monthly to collect data at one or two streams in the area.
Creative Nature Study at The Cabin Path (K-12)
This outing will introduce students to The Cabin Path, an amazing privately-owned nature center in South Fulton (directions to be provided). The center is operated by Sarah Crutchfield, an enthusiastic and creative environmental educator. She will give students a tour of her woodlands and lakes, including a stone labyrinth and original pioneer log cabin. Then we will participate in one or more creative projects with Sarah, such as building outdoor fairy homes or crafting insects out of found natural materials. This outing is intended as an introduction to The Cabin Path and opportunities for doing natural history study and creative environmental art there; should there be sufficient interest, Dr. Blizard will be collaborating with Sarah to offer a monthly (or possibly weekly) nature study program there. You can read about The Cabin Path at http://www.thecabinpath.com/.
The Natural World Close-Up: Insects and Other Small Wonders (K-12)
This outing will take place at The Cabin Path, a private nature center in South Fulton (directions to be provided). The center is operated by Sarah Crutchfield, an enthusiastic and creative environmental educator. She will give students a tour of her woodlands and lakes, including a stone labyrinth and original pioneer log cabin. On our walk, we will explore the diversity of local insects and their habitats, including dragonflies, butterflies, and beetles. Valerie Hayes, a nature photographer, will accompany us on our walk, and will share some of her close-up insect photography with the students. (Check out The Cabin Path at http://www.thecabinpath.com/, and Valerie’s artwork at http://www.flickr.com/photos/67363961@N00/.
Georgia Archaeology (grades 3 and above)
On this outing, we will hike through the woods to the ruins of a couple of 19th century agricultural buildings and an abandoned family cemetery. While there, we will learn about how an archaeologist might conduct an excavation in order to learn more about the past from the site. This outing is intended as an introduction to archaeology; should there be sufficient interest, Dr. Blizard intends to offer a hands-on archaeological excavation opportunity for interested and dedicated students. That program would meet once a week for about three months, and would involve actually conducting a small-scale excavation, most likely one investigating prehistoric remains in the region. Our goal would be to document what we find, and report it to the state of Georgia for their database (see http://shapiro.anthro.uga.edu/GASF/site_pamphlet.html).
If you are interested in arranging one or more of these outing opportunities for your students (minimum of four participants and maximum of twelve, please), contact Dr. Clifford Blizard at firstname.lastname@example.org or feel free to call him at (770)-463-2887.

Against the Grain
Cochran Mill Park Quest #2
To complete this quest, a field guide to trees might be helpful. Park along the south side of Cochran Mill Road, about a thousand feet southwest of the entrance to Cochran Mill Nature Center, directly opposite the ruins of a brick chimney in a fenced yard. Follow the trail over a rope barrier (now lying on the ground). After walking a few feet, turn right to parallel Cochran Mill Road. You are now on the trace of the original roadway.
Follow the old road, continuing to be alongside the present-day one, until you see a dip in the trail. On your left, on the wooded hillside, are terraces that farmers used for growing cotton here. They are probably from the early 1900’s.
Come to where the road cuts through some rock. Lichens and algae cover the rock in many different colors. The brightest color is __ __ __ __ c __.
Continue down the path to a big fat tree on your right, just beside the path. It is probably over 100 years old. It is a __ __ c __ __ __ __ __.
The bridge that you come to crosses Bear Creek. Cross the bridge and take the path to the right. You are still on the original Cochran Mill Rd. route.
The road soon turns completely to gravel. On the right is a star-shaped stump, and behind the stump is a big rock. The rock has long s __ c __ __ __ h marks on it. What do you think these are from?
Continue down the former Cochran Mill Rd. On your right is the forested floodplain of Little Bear Creek. Continue straight down the path until you come to a bridge. The bridge is unusable because of its age. It is also part of the original trace of Cochran Mill Rd. Just beyond the bridge are the ruins of an old mill, from the late 1800’s. It is the oldest mill in the park. The only things left of the mill are a few stone walls. Standing where the mill used to be, if you face the falls, you will see a path to your left, going up the hill along the stream edge. It goes over a rock to start, and may be hard to see. Not far up the path is a rusted metal __ c __ __.
Continue up the hill if you want to see the mill dam, mostly destroyed by vandals in the 1970’s. When you come back down the path and back to the mill site, look to your right. Hidden by vines are a couple more mill walls.
When you are done looking at the mill, start to go back along the trace of former Cochran Mill Rd., the way you came. You will see a path going uphill to the right. At that fork, look right. There is a __ __ c __ __ __ __ c.
On the left after a hundred feet or so, you will see a cleared area. You are on the driveway of an old house. Can you find the concrete pad, hidden under the leaves, where the garage probably was? Can you trace any of the outlines of the now-demolished house? All that is left are some bricks and some sheets of metal. The house is from the early 1900’s. The mill owner probably lived there.
Follow the steps up the steep hill. At the top is a bench, where you can stop and rest. Follow the main path down the hill. Don’t slip. When you reach the Bear Creek again, go left. A __ __ c __ __ __-down tree makes a great bridge for squirrels to cross Little Bear Creek. When you come to a sign (in concrete, but not stuck in the ground) go left onto Loop Trail A.
When you come to another fork, go left again. Look around while you walk. After a while, on either side of the path you will see piles of rocks in a rough line crossing the trail. This is likely the remains of a stone __ __ __ c.
Down the path a little further is a clump of Christmas __ __ __ __ c. Their name is easy to remember, because they have leaflets that look like Santa’s boots. On the right are some more old farm terraces.
When you come to a sign that says “Trail,” turn right and hike up the hill, along a path lined with rocks. Continue on this path until it goes downhill. Once you pass a bench and a plank bridge, take a side trail to the left. As the trail approaches Bear Creek and starts heading back up the hill, you will see a stone wall on the left, near the stream edge. Turn left on a small path to go to the ruins of small building, constructed in 1906. Water flowed over a turbine here, making electricity for the city of Palmetto in the early 1900’s. Look for a gap in the wall that holds the box with the final clue in it. Watch out for the hairy vines and three-part leaves of poison ivy, which covers some of the walls.
Take the letters in the boxes from the answers above and rearrange them to find the answer to this question:
What was the oldest building in Cochran Mill Park used for?
It was a __ __ __ __ __ __ __ __ __.
When you have found the red box, answered the final clue, and stamped your Quest book, go back down the trail the way you came, all the way to the “Trail” sign. Don’t turn left! Instead, continue straight ahead along Bear Creek, until you see the footbridge across the creek. Turn right, cross the bridge, and follow the trace of former Cochran Mill Road back to your car.
Sadly, most of the structures in the park were severely vandalized in the 1970s and 1980s. Two mills were burned by arsonist's flames, while a more recent picnic area was utterly demolished (with one picnic table currently underwater at the base of the largest waterfall in the park). I am disappointed that such a lovely place, with such rich historical significance, can have been mistreated to such an extent. Even the trail signs have been damaged. Several are missing altogether, while others have graffiti on them or have been pulled up out of the ground. Graffiti used to cover the underside of the supports to a pedestrian bridge across Bear Creek; our school scrubbed away some of it, but ghost images of the older paint still remain. I am baffled that such a rural and rather remote location has been visited by such damage. Visiting the park, I begin to wonder about the value of place-based education. If greater awareness of local "treasures" (historical or ecological) means greater visitation, doesn't that increase the likelihood, in turn, that vandalism would occur? Are fragile landscapes best left unknown and relatively hidden, or protected by park signs that are easy to ignore?
With those thoughts in mind, here is the text of the first of our two Quests:
A Shocking Conclusion
Cochran Mill Park Quest #1
To complete this Quest, a field guide to trees might be helpful. Park in the Cochran Mill Nature Center parking lot. To get to the trailhead for this quest, walk back down the gravel entry road along the edge of the pond. Turn left and walk downhill to a trail sign. Take the wide, flat trail straight ahead of you, now known as The Waterfall Trail. This path used to be the access road to the mills along Bear Creek, whose ruins you will visit during this quest.
As you walk down the straight trail, you will notice a pile of rocks a short distance off to the right. __ __ __ __ c __ covers many of the rocks.
Continue on the path until it curves to the left. At the bend, you will see a large fallen pine tree that has been partially cut into logs. It is the same kind of pine that commonly grows in this part of Georgia, including along this trail. What kind of pine is it? __ __ __ c __ __ __ y.
Continue for about ten minutes along the trail, passing a small rock outcrop on the left. You will come to a place where the trail leads out onto bare rock. What kind of rock is it? You can take it for __ __ __ __ __ __ c.
Follow the sound of flowing water to the remains of a large dam. You will walk past an area on the right where we did some privet removal a year ago. The privet is already on its way back, though. You will see several small evergreen trees growing among the privet. What kind of tree are they? c __ d __ c s.
Stand at the stream edge, facing the broken part of the dam where the water flows over the edge of the wall. (The dam was originally constructed sometime in the 1930s; vandals broke the dam in the early 1970s.) Notice that, when viewed from downstream, the dam face has a series of steps. In side view through the gap in the dam where the water flows, you can see that the widest part of the dam is toward the bottom, and the narrowest part is toward the top. Why do you think the dam was built that way? After pondering this, turn away from the dam and face the woods. You will see a brown trash barrel. Take the narrow trail toward it. Near the barrel, along a wide path, you will see a large tree. Look around on the ground for its leaves, which have rounded lobes to them. What kind of tree is it? __ h __ c __ __ __ __.
Take the wide trail upstream until you come to a fork in the road. Look to your left, and you will see some ruins of an old house. It was built in the first decade of the 20th century, for the mill operator and later, the resident caretaker of the property.
Continue straight up the path for several hundred feet. Be watching on your left for the ruins of a small concrete structure that once had a flat wooden top to it. What do you think that it was? A __ __ c __ __ __ __ __ __ __ __. A group of bikers, the story goes, vandalized this part of the park in the 1980s.
Continue on the trail upstream until you arrive at a second large rock outcrop that the trail crosses. Look right, and you will see the ruins of a former mill, originally constructed by Barry Cochran in the late 1800s for the grinding of grain. A wood-framed building, it was destroyed by a fire set by vandals in 1972. Amid the ruins is a large wheel made of rock that was a very important part of the mill operation. What is it? A __ c __ __ __ __ __ __ __.
Between the ruins and the stream is a very weedy area; however, if you feel adventurous, walk toward the stream edge, and you will find the water wheel support foundations. Look out across the stream. Until the dam upstream was broken in the 1970s, that area was a pond. Hiram Evans, who owned the park property in the 1940’s, had the lower dam constructed to create this pond, but it was never used to power a mill. Instead, Evans had a building on stilts constructed in the middle of the pond, with a causeway accessing it that ran from the mill building out into the pond. Locally known as “the fortress”, this building had a checkered history. Hiram Evans was the Imperial Wizard of the Ku Klux Klan; supposedly, he used the building for secret Klan gatherings. Later on, in the 1960s, parties were held there. The house burned down in 1972, in the same fire that destroyed the mill.
Continue on the trail upstream to another dam. Along the way, you will notice several concrete structures sticking out of the rock. The larger, low ones were foundations for utility poles; the tall, narrow ones closer to the dam were pylons for a penstock that carried water from the upper millpond down to a structure you will see later on this Quest. The dam itself dates to the mid-to-late 1800s, and is built of local stones without mortar. Sections of it were replaced by volunteers in the late 1970s. There is a pipe sticking out of the dam. How many layers of stone can you count above the pipe? __ __ __ __ c.
Turn around and start back down the wide trail downstream. You will arrive at a fork in the path, with a large pine tree straight ahead. Take the left fork. Once you reach the rock face, go slightly left, and follow a path leading down to Bear Creek, past several clumps of star moss. The trail continues along the stream edge. Look across the stream, and you will see a small rock-and-cement structure. This building was a generator house, constructed in 1906. Stand at the edge of the stream in a location directly opposite from the near corner of that structure. There should be two slender trees near the stream bank that make a “doorway” through which you can view the generator house. Turn around and walk away from the stream edge. Walk until you cross a gully/path, counting the number of steps it takes you to get there. Round that number of steps to the nearest ten, and write it here: __ __ __ __ c.
Continue to walk in the direction you were going when you reached the path/gully, taking about the same number of steps that you wrote above. Look for a box with the stamp pad and book for this Quest.
Finally, arrange the letters inside the boxes in each answer above, to find the answer to this question: "The generator house is the newest structure along one of the streams in Cochran Mill Park. From 1906 until 1918, it was used to produce something for the City of Palmetto. What did the generator house make?"
__ __ __ __ __ __ __ __ __ __ __.

My plans for the day had been shaped by an earlier run down the river. Ben Simms (outing leader) and I had completed a scouting run on a warmer but windier day a couple of weeks earlier. It had not rained in ages, and the river was quite low, with abundant rocks lurking in the shoals. We made it through without incident, though for a considerable portion of the trip we faced headwinds great enough to turn my canoe and almost push me back upstream through a stretch of rapids. It took us five hours to run the approximately ten miles. Ben, accomplished river runner, glimpsed all sorts of wildlife, including an otter; I contented myself with several great blue herons (or was it the same heron that we kept chasing downstream?).
Anyway, Saturday's run was different. It had rained all day the previous day, and the river had risen over a foot from our earlier trip. The wind had abated, and we raced downstream with very little effort. The few morning clouds quickly lifted, and the sun shone brilliantly in a clear blue sky.
We zipped downstream, quickly (and unknowingly) passing the spot where we had planned to pull out for lunch. We were so early in the day that it had not yet been flagged for us -- we later calculated that the flagging must have been put up within five or ten minutes of our passage. Meanwhile, I kept my canoe as close to the Fulton County bank as I could -- balancing that against my wife Valerie's requests from the front of the canoe that we keep to the sunnier middle of the river. As we glided along, we passed by a dramatic example of bank collapse, in which a huge chunk of riverbank, trees and all, had sluffed off into the river. It made me think of our current economic woes and other failing banks....

At last, as we bumped along the road (of sorts), I reflected upon how the wonders of the Hill Country's rural landscape become particuarly noteworthy when one gets off the roadways. Then, for instance, I can feel renewed amazement for being able to experience such bucolic farm scenes as the one below (looking past a pasture oak and toward Wayne's farmstand off Hutcheson Ferry Rd.), yet live only a dozen miles from the City of Atlanta.
Tuesday, September 23, 2008
Mostly, though, I think about the soil. There is a new soil survey for Fulton County -- 2008 -- and and older one (and more intriguing, for its age), from 1958. The soil names have all been changed in the interim, and the aerial photograph used as a base is correspondingly newer, too.
Nonetheless, my favorite local aerial photograph is the one above. It shows the crossroads of Goodes, southwest Fulton County, as it appeared from an airplane sometime in 1938 -- back when a lot of the erosion was still going on, when the topsoil was still on the move. Goodes is more noticeable on an aerial photograph or map than it is from the ground -- the roads come together in a distinctive pattern that lends character to what otherwise would be just any other highway intersection in what passes for "country" outside Atlanta. From the ground, Goodes is just a sign like an old-time gas station kind, easily overlooked.
But in the aerial photograph, I can spot Goodes among dozens of other highway crossroads. Rico residents may have the old schoolhouse that is now City Hall, Police Station, Community Center, and Library all rolled into one (and they may have the volunteer firehouse, too), but we have that strange crossing of roads where the north-south Atlanta Newnan Road is offset, with Rico angling northwest in-between its two sections. A geologist, examining the crossroads, would declare Hutcheson Ferry Road a fault line, and pronounce the movement right lateral.
Hutcheson Ferry is hardly a plate tectonic boundary -- we are fully in the United States, deep in the heartland, as the soundly Republican tone to the political signs on homeowners' lawns remindes me. But it is a boundary of another sort -- a drainage divide, separating small subbasins within the Chattahoochee River Watershed. To the north, along Rico Road and in the woods just across the street from my house, a brook flows in a narrow but deeply-incised channel, eventually joining another stream, flowing into Longino Creek and then at last into White Oak Creek, and thence into the Chattahoochee River. To the south, the water flows into ephemeral gullies, like the one behind Hill Country Montessori School, and then into Cedar Creek, which briefly serves as county line between Fulton and Coweta Counties.
All this shows that, if not the center of the universe, Goodes is a fascinating place to be. But, as Brian Swimme the theoretical cosmologist reminds us (to go from the crossroads to the cosmic for a moment), we are in an expanding universe where every point is a center of expansion. So every place is the center of the universe. Goodes is as good an axis mundi as any other one, and perhaps a bit more distinctive when viewed from above (or nowadays, from Google Earth). But other spots are intriguing in their own way, if you slow down enough to read them -- to study their chorography. That, I suppose, is the irony of being a proponent of reading the landscape -- I become proficient at reading stories in the immediate earth where I live, but I do so with the hope of encouraging others to do the same in their own places.
The stories are different, perhaps, though too many are, I fear, variations on a theme of loss. After all, no places on this continent will feel again the whirlwind force of a visit by a sky-darkening flock of passenger pigeons, and no tree will shake with the tropical chatterings of a flock of Carolina parakeets. The elm tree is gone, apart from a large specimen I found along a trail at Etowah State Historic Site. And the chestnut is gone, too, apart from a few tentative saplings that die young and diseased (awaiting a naturalist equivalent of A. E. Housman to celebrate them), and a dozen that made National Public Radio news last year for lingering into adulthood on the slopes of Pine Mountain, well south of here.
I was the speaker in our Sense of Place Series this month, though I did not cover anything I wrote above (except the lost topsoil part). I drew upon the work of an ecologist at the University of West Georgia, Joe Hendricks, presenting one of his Terrestrial Ecology PowerPoint presentations to offer the half-dozen audience members a sense of the landscape history of this region. Then I showed the Goodes aerial photograph from 1938 -- a travel back in time to when terraces were still bare -- covering parts of the land with patterns akin to suminagashi, the inky swirls of Japanese marbled paper. Then I showed them images from a walk in the woods I took last year, with scenes evoking stories in the landscape.
Above is what I wanted to say, or begin to say, or struggle to make sense of -- the mysterious force that compels me to find new stories in the land, the way I have become so taken with the crossing of roads I walk every day, the way I thrill to the discovery of another trace of abandoned fenceline, the sorrow I feel when I look across a gully at a white oak over a hundred years old, once a pasture tree and now, roots exposed, holding for life onto a mound of soil. And I think of the distance between that oak and me, a distance once filled with earth, now not capable of being bridged. It is a distance in space, of course, but also in time, back to a time when the soil was black not red, and the forests were composed of oak and hickory, not these weeds of loblolly and sweetgum I now find cropping up wherever I leave the lawn unmowed. We cannot go back -- Georgia will never again be the wilderness that William Bartram explored, or where, centuries earlier, Hernando DeSoto first encountered the remnants of the Mississippian civilizations (once called "The Moundbuilders"). The gullies are largely stable now, except perhaps after a heavy rainstorm. Then, briefly, the water may trace out with muddy fingers the gullies' former paths, leaving behind a thin blanket of silt in its passage over pine needles and sweetgum leaves and branches and bare earth.

We caravanned to Dunaway Gardens just south of the Fulton County Line in Coweta County, where the gate was opened for our entourage to enter. The gardens, otherwise closed for the weekend, were opened just for our group. Throughout our visit, we relished the experience of being on our own in the gardens, in contrast to our visit earlier this year, when our trip coincided with several large garden tours and an afternoon wedding. Garden maps in hand, we hurried downslope to the edge of Cedar Creek. Although the path was well-mowed, my feet were still quickly drenched by the early morning dew.
Gosh, did we see a lot of insects, though! Greg, sporting an insect net, was full of glee, snatching up all sorts of treasures in his net. It was still cool enough in the early morning that the dragonflies were motionless atop plant stems, and an easy catch. The first one we found, a slaty skimmer, is pictured below. This is the dragonfly that subsequently befriended Tara for much of our morning.
A few minutes later, Greg was using his net to try to catch some aquatic denizens of a small pond adjacent to the creek. He quickly found a water scorpion -- an insect belonging to the order Hempitera, or the "true bugs". Related to the terrestrial "walking stick" insect, water scorpions are air-breathing predators that feed on smaller insects, such as mayfly and stonefly nymphs.
In another few minutes, Greg had located a "tent" belonging to a cluster of tent caterpillars in a shrub along the streambank. Based upon their size, the larvae appeared to be almost ready to pupate, emerging afterwards as small, reddish-brown moths.
Continuing along the riverbank, we saw another dragonfly, perched calmly on a blade of grass. I snapped its photo before it flew away.
We continued along the creek's edge, stopping to scan the far bank for birds, but to no avail.
The prize find of the day, in my opinion, was a sleek green tree frog that I noticed on a cattail reed, blending in almost perfectly with the stalk. A moment later, a green dragonfly (possibly a pond hawk) landed on a nearby reed and perched there for a group photo.
I returned to the site a few minutes later, and the dragonfly had flown away. I did get a splendid closeup of the green tree frog, though, who remained motionless there, against the backdrop of Cedar Creek.
At last we wended our way up through the gardens, finding quite a few butterflies but only a couple of birds. We heard a woodpecker's call through the trees, and briefly saw a cardinal who scolded us from a shrub along the path. Tara, Greg, Valerie and I inspected another set of shallow ponds (Arrowhead Pools) that had been constructed as part of the gardens. Tara found an intact snakeskin in the shallows, but the birds (including a heron known to haunt the area, feeding on the pond's goldfish stock) continued to elude us.
