The tradition in my family for about 30 years has been to gather at my oldest brother’s house for Thanksgiving. Numerous traditions grew up around this basic idea. One of the most enduring is the day after hike (see “Cascades and Escapades” and “Ebb and Flow of a Tradition” as two recent examples).

Of course, you can guess that this year was different. We didn’t meet at the elder brother’s house. His immediate family did. They also went on their hike. A good portion of my immediate family met at my house on Friday for thanksgiving reflections and a meal. There was plenty of good food prepared by numerous hands. We read psalms of thanksgiving and sang hymns and shared things we are thankful for.

On Saturday, prompted by two of my sons, we took a hike. My youngest and a young friend were beginning a one night backpacking trip, and the rest of us were along for the views and conversation. The slope had been burnt over twice about 15 years earlier and eliminated much of the topsoil. Regrowth has been slow, but the views are good.

The backlighting turned out OK, but since we did not know that at the time we shifted 180 degrees and posed again for the friendly hiker that I asked to record the images.

My son admitted that he was overly packed for a one nighter.

There are patches where it was not completely burned off and the younger trees come back faster here with the presence of more soil.

New growth is heartening.

The previous pictures show the relatively shallow slope the southeast face of the Shortoff Mountain. The next one shows where the trail comes along the edge of the vertical northwest facing precipice.

Table Mountain Pine predominates the stressed conditions of shallow soil, wind blown and otherwise drying conditions.

You wouldn’t be surprised to discover that this young friend is a tri-athlete. He stands upon metamorphized layers that are common to the Gorge.

Lake James actually dams three parallel streams, two of which are visible here. The South Mountains are visible in the background, being the last foothills before subsidence into the Piedmont region.

Wind is a creative and random sculptor of trees, imparting to this specimen a bonsai appearance.

There are many lone trees hanging onto the cliffs but the pine on this vertical section seems somehow “braver” or “more determined” as anthropomorphisms would have it.

Table Mountain Pine is also one of those species that require fire to open the cones and germinate the seeds. The cones appear to be fortresses against their time of opening.

Shortoff Mountain is amazingly flat on top as seen in this view along the Mountain to Sea Trail.

I know that fire is necessary and unavoidable, but I hate what it did to this little pond. First of all, it is amazing that a pond exists at the summit of a flat-topped mountain. It is not a mere wet weather pool. It used to have shade, open water, abundant frogs, small fish with only minimal vegetation in the water. Now the pond has eutrophied to such an extent as to hold no discernible animal life.

Not knowing that it was there, I had to point out to my young friends that we should stop and look at the best view of Linville Gorge available. Because the Gorge turns slightly at the mouth, you stand here on the rim looking straight up the majority of the length of the Gorge.

You can tell by the quality of the colors that this picture was not taken with my phone. I credit my daughter-in-law for this good picture.

And here she is with her husband.

Near the previous view is another one facing out of the mouth of the Gorge, revealing ridges more than 30 miles away.

I conclude with a picture of me contemplating the change and continuity of God’s nature. We can design our Biosphere 2 in an attempt to copy the real thing*, but our attempts cannot hold a candle to the ability of God’s designed Biosphere to absorb stress in the form of weather and natural disaster and human pollution and still recover and adapt. Man may have caused the fire that so affected this pond, but lightning could have just as well accomplished the same thing during drought. The pond may be changed for the duration of its existence or it may eventually recover its shaded, lively charm. Either way it is and will adapt well.

*If you don’t believe in design in nature, just consider the extent to which scientists go to design experiments like Biosphere 2 and they don’t even work that well.

One of the projects I am involved in is the development of a trail behind our school. Given the committee’s desire to include the community, churches, and 4 schools in the development and use of the trail, I suggested naming it the Enola Community Trail (ECT). And so it is. The timing of this community trail was sequential to a student initiated emphasis on helping others, exercise, and the outdoors. An English teacher at my school took¬† their idea and coupled it with a trail I had already developed in the woods behind our school. (I may ask her to guest blog that huge side of the story.) She asked me how we could use the trail to get students outside and moving.

The idea for a trail originated with a class I taught for about 6 years called Advanced Biology. I basically wrote the curriculum, a fact that I should not admit to in public. That was probably the demise of the class, since it did not have a state mandated test and didn’t have an approved, curriculum specialist, set curriculum.

Now that doesn’t mean we didn’t work and learn, because there is nothing I hate worse than wasting time. In fact, if a class of 30 students wants to pack up 5 minutes early, I point out that they are intending to waste 2 1/2 man-hours of work. The class included the indoor studies like dissecting cats (once or twice a piglet and shark as well) along with a body organ quiz and extended discussion on binary classification, using stereoscopes to identify student made collections of insects, spiders, wildflowers, and also trees as the season allowed, preparing powerpoint presentations about a body system to present to the class, and researching and writing a paper on an organism of the student’s choice which included characteristics, ecological importance, range, population (including level of endangerment), and usefulness for food, medicine, shelter. The outdoor studies included making collections, trap and release studies, game cameras, succession and soil studies, reflections, creek studies (from dissolved oxygen and macro-invertebrates to erosion) and building projects. We built two bridges, one to cross a creek and one to cross an erosion ditch, two bird nesting boxes with a camera in one, and a pole with bat box and raptor nesting site above. Behind the school there was a small kudzu patch, a large briar patch, two old fields overgrown with trees (one dog hair stand and one with young trees and vines so thick you couldn’t see 15 feet), a monoculture of Eastern White Pines, a large lawn, a hay field, a riparian zone and creek, a small intermittent wetland, and a patch of what seems to be virgin forest (…or at least long undisturbed. It is still there with old growth trees next to a meander in the creek at the odd corner of 5 properties. Mayapples, Doghobble, heavy leaf cover, and 10+ varieties of large hardwoods grace the scene. I call it ‘Beauty Spot’.)

To access these places I had the students begin to build a trail. It was a narrow, single-track path, with two grades cut into the side of banks with mattocks and shovels. The students dug, trimmed, cut, sweated, and occasionally played in the creek. We would frequently stop to talk about a spider someone saw or wildflower, or a bird overhead, or the change in type or smell of the dirt. At first the students whined about the work, but by halfway through the semester they would beg to go out and work, or sit and talk about nature.

One project was fun to surprise the students with. I would lead them down to ‘Beauty Spot’, a solid 1/2 mile walk from our classroom. Then I would explain that they were to lie down in the leaf litter to look, listen, smell, and feel the surroundings for 10 minutes in stillness and silence. It was very difficult to convince them that it is OK to lie down in the leaves. Questions of bugs, snakes, spiders, filth, and more were common. I usually had to plop myself down and call for them to lie down around me. Then I would quiet them and say no talking or movement, or we start over. When I called time, I told them to write down as many things in their journal as they could remember. Next we discussed what we observed. I added as many other things as I could to help them see the need to hone observation skills. Several students would reflect then or later that it was the most amazing outdoor experience they had ever had. I was always amazed since I have spent many hours over many years doing just this, especially on backpacking trips. The opening of their minds and hearts to the significance and love of nature I called ‘Affective Biology’.

I guess we would have run out of trail building and significant maintenance eventually, but it didn’t happen in the six years I had the class. One regrettable reason for this continuance of need to maintenance the trail was the growing kudzu patch. I wrote above that is was a small patch. I warned and pleaded about the coming doom to the wonderful variety of habitats in such a small area, but to no avail. I even had borrowed a goat from a student’s grandfather to test the idea of goats controlling kudzu. In this preliminary study, we checked on the goat every school day to give it water. It was confined in a ten by ten, portable chain link enclosure. That little goat could denude 100 square feet of ground with chest deep (on a human) kudzu every 3 days. Oh, to have a little flock with fencing and small shed to solve the problem ecologically and educationally. Instead, the goat was stolen by a ‘concerned’ student and her uncle who thought we were being cruel to animals by ‘experimenting on a goat’. Never mind that kudzu is nutritious and edible by humans as well as goats. It was quite a surrealistic scene when the goat was returned a week later before the eyes of the class and grandfather.

To say the Advanced Biology class was the best part of my teaching career is an exaggeration and misunderstanding. It was good because of the challenge to me to find new things to study, the truly hands-on activities that didn’t include more than about 3 or 4 lectures from me the whole 90 days, the time outdoors, and the change I saw in students. But the best part of education is the interaction with young people at their moments of wanting to understand the world around them, the meaning of and best way to live life, and humor and warmth of relationship. You have to plow through a load of interaction that is anything but that to experience it, and it doesn’t seem worth it much of the time. I have had those significant discussions with individuals and whole classes in all of the various classes I’ve taught. You just have to seek it and wait for it.

So, I guess this whole blog entry is a side-track, since the title has been largely neglected thus far. When others got involved, they envisioned more of a walking, jogging, eight feet wide greenway style trail, and so it is becoming. In reality, it does not detract from my original intent of nature studies in various habitats, because the trail mostly traverses the growing kudzu patch and might hopefully be the final demise of the same. “Beauty Spot” is still there and the creek is largely undisturbed. The new trail may even result in an outdoor classroom and a wetland/catchment basin to solve an erosion problem.¬†

One of the problems of such a project like this is conveying and passing on vision. You might have thought I would say getting funding, but as individuals and organizations understand our vision, they want to help. But how do you get the wider community excited about something they can’t see or is only partially formed? It is as if you must reach critical mass of manifest vision before the many contribute money and manpower. We may be approaching that mass, or at least, we hope so.
