Eastern Continental Divide: North of Gainesville

Picking up where the last one left off, this gets you out of the burbs and into the woods. At the northern end, it gets you into the mountains, even.

The route through Gainesville is rather arbitrary and I’m not sure how close it follows the divide.

You are pretty much running parallel to US 23 (when you are not actually on US 23) all the way.

The early parts of this route are very close to Lake Lanier.

From Lula through Mt. Airy, you are running directly beside the Norfolk Southern main line.

I have only been as far north on this route as Alto, so I can’t really say what the remainder of it looks like.

The end point here looks to be about as far as you can follow the ECD on public roads. From here, the ECD turns westward and generally forms the Habersham/Rabun county border until meeting the Tennessee Valley Divide at Young Lick.  I don’t see any roads that directly follow this ridge, not even dirt Forest Service roads. From Young Lick, the ECD continues north on the Appalachian Trail. At that point, following the divide becomes more of a matter of hiking than driving.

Eastern Continental Divide: Duluth to Gainesville

Picking up where the previous route through Atlanta ended, this follows the ECD (within the limits of road placement) through the northeastern metro area. To be honest this is a rather boring drive through the suburbs. You can skip to the next post to pick it up where things get mildly interesting again.

The earlier part has some shenanigans with Old Peachtree Road, leaving it without turning and turning to stay on it at different points.

The segment on GA 20 is an area where no road follows the ECD. If you look close at a topo map you’ll see this section crosses a creek, not something you’ll see when following a ridge line.

The segment on GA 124 passes the site of Ft. Daniel, one of the original endpoints of the trail that became Peachtree Road.

The GA 13 portion mostly runs closely parallel to I-985.

Gainesville’s airport is an arbitrary stopping point dictated mainly by limitations on the number of route modifications that Google Maps allows you to make.


(Aside: notice how close the divide is to Lake Lanier? The western edge of Lake Lanier’s drainage basin is also visible on this map, over near GA highway 9. The lake is really not very far at all from the boundaries of the area drained by it.)

Lynyrd Skynyrd’s recording studio is now an anonymous warehouse in Doraville

Per Wikipedia:

Studio One was a recording studio, located in the northern Atlanta, Georgia suburb of Doraville. The address was 3864 Oakcliff Industrial Court, Doraville Ga 30340. It is now occupied by a non related business and used as a warehouse.

Check out the list of albums recorded here, it includes not only four Lynyrd Skynyrd album but also probably the earliest recording featuring Ronnie James Dio on vocals.

In the 1970s and 1980s Doraville was a haven for blue-collar white Southerners, aka rednecks. This was gone by the early 2000s, as much of the original population was displaced by immigrants.

This is what the address on the wiki page looks like today. I almost have a hard time believing it. The red car in the center of the picture is parked next to the door of number 3864.


Howell Wye? More like Howell Weeds

One of the constant elements of southeastern railfanning is kudzu, sumac, honeysuckle, wisteria – you know, weeds. As summer turns to fall, we have one last chance to appreciate all that luscious green foliage.

Trains sneak out of the underbrush like wild animals.


In a few months this will all be gray and brown.


By the way, Pokeweed was traditionally used as a source of food in the South and in Appalachia even though it is toxic. I guess our ancestors would rather risk being poisoned by their food than not having any at all.

Sumac, visible in most of these shots, has some species that are used as flavorings (such as for tea), but I wouldn’t try it with this wild stuff.

Edit: this is probably Rhus glabra, smooth sumac. It is supposed to be edible, although it is not the same species cultivated for tea.


Kudzu leaves are edible as well but in the South you never know that the kudzu you pick wasn’t sprayed with something nasty in an unsuccessful attempt to kill it.


All these plants attract bees and wasps, which were buzzing around during these shots, although it was kind of hard to hear them over the trains.

Union Hill Road: Cemetery, Ghost Roads, Skeleton Houses

Sometimes I use Ronald Reagan Blvd as an alternate to GA 400 between exits 11 and 12. This road goes through mostly vaporware developments – planned subdivisions, some of which don’t seem to have even started construction, others seem to have had some grading and nothing else. Lots of places where they put it in a turn off of the main road but it just dead-ends into a field. That sort of thing. This is literally where the streets have no name.

Recently I noticed, off to the west side of the road, what appeared to be a graveyard on a hill overlooking a construction zone. I decided to try to find it.

Now, on the map, it looks like you can get there via Union Hill Road:


But, where I drew that red line across the road, that’s where you find this gate:


So, clearly I’m not driving there. It was a nice day for a walk, though. You can  of see some traces (as in the next photo, on the right path) that this road was once paved, but the pavement is very much going back to nature. Maybe it will someday again be paved. I hope not.


At the end of the road is another gate. This one has a “no trespassing” sign but the sign is facing the other way from where I came. I don’t know who they are trying to keep out from that direction.


Beyond the gate is the cemetery:


Most of the graves seem to belong to a James family, and on the topographical USGS map this is in fact marked as “James Cem”. The most recent date I saw was 1978, but they are mostly 19th century dates. Confederate flags are planted next to several that are Civil War era.



This graveyard clearly is still maintained, someone cuts the grass here and those flags look pretty new.

After this, I decided as a bonus to explore some nearby old houses back on the road.

This is all that’s visible from the street, and really gives no clue:


The inside of this building has some graffiti, but even that is dated from 2001!

IMG_7999 IMG_8002

Dig this chair!


The adjacent buildings here are nothing but frame. Only a little bit of siding remains, someone has removed the rest of it.

Now all the remains is the “bones”, facing out over the empty field.




All those new neighborhoods being built nearby, some of those people in those houses must have kids. I hope those kids run around unsupervised in these fields and these woods and ruins, trespassing and risking injury. One can dream.

Bayou La Batre and Coden

This is the first time I’ve posted anything of my hometown on this blog since I restarted it on WordPress.

On a recent visit “home”, I went around Instagramming not the usual sights of the town (that is, boats and the water) but other aspects.


“S” logo on the sidewalk in front of the old Schambeau’s store. Schambeau’s, or Crum’s as the old folks called it (the propreitor was A. C. “Crum” Schambeau) was one of the most important businesses in town. They sold groceries, hardware, lumber, paint, you name it.

Schambeau’s was one of the two main sources in town (along with Modern Drug, not pictured but believe me it was not very modern at all) for comic books, an essential ingredient of late childhood and early adolescence in the 1980s as now.

If you had to go to the bathroom in Schambeau’s, you had to go back behind the meat department and up a set of stairs, past the office where Mr. Crum did his accounting on some kind of electromechanical monstrosity of a 1960s calculator, to a single unisex toilet with an oddly religious painting decorating the wall.

That isn’t remotely all there is to say about that place.

The Yellow House

This next picture was a house around the Coden Belt road that, back in the 80s and early 90s, was (per my mother) a boarding house where all the known homosexuals in town lived. The landlord was another one of the Schambeau family. I assume the house reached this state of disrepair from Hurricane Katrina.


This is what the dirt lane beside that house looks like:


The Shell Fence

Just down the road a piece is the place with the oyster shell fence. This was, I am told, once a common local building material – there was once a “shell house” in town made entirely of it.




Coden Drive-In

The “Coden Drive-In”. You need to understand that “Coden” is pronounced something like “Code-Inn”, so the name of this place rhymed. The building got like this from Katrina but I don’t remember if it was in business right up until then or not.

There wasn’t much to do in Bayou La Batre and Coden back in the late 70s and early 80s, so my family’s idea of a fun evening when I was about 5 years old was to come to this place and get ice cream cones, and then go driving around watching the sun set on the bay while we ate them.

The Catalina

The ruins of the old location of the Catalina seafood restaurant, which everybody called “Ory’s”. The restaurant was closed for years after the hurricane but now is open in the old Schambeau’s building:


Royal Oaks

“Royal Oaks” is one of the few remaining homes from Coden’s days as a seaside resort in the l890s. This period of prosperity was ended by disastrous hurricanes in 1906 and 1916. They had no names then, just “the 1906 storm”.


Peter F. Alba School

And now, Alba. The school where I spent the blerst of my childhood. Now only a middle school, in my days Alba served  kindergarten through 12th grade.

This caboose was installed when I was in high school. No predecessor of CSX ever ran to Bayou La Batre. (The only railroad in town, long since gone, was the Mobile and Bay Shore, a Mobile and Ohio subsidiary. If it had not been abandoned or sold, it would be part of Canadian National now.)


All of Alba’s “portables” – that was what they called a classroom trailer back then, a “portable” classroom – are gone. I don’t know if the hurricane got them, or if the school wasn’t crowded enough to need them anymore after the new schools opened and took most of the students. Now this was once a covered walkway that kept students out of the rain on our way to class, now it is just sitting in the middle of nowhere.


This was the satellite dish that we used to receive “Channel One” broadcoasts in the 90s:


And now, the Walk of Fame of 1991. That year, the school put in a new sidewalk and allowed students to sign it. I looked and looked for my own name, but could not find it. I know almost all of the names as people I went to school with though.







Tunnel Springs, Alabama

Near the town of Tunnel Springs in southwest Alabama is a feature normally reserved for more mountainous areas: a railroad tunnel, abandoned for years, and relatively easy to find.

The tunnel is located up the abandoned line past the north end of what is now the Alabama Railroad. Wikipedia gives us the date of construction of the tunnel as 1899:

The route of the Alabama Railroad was originally constructed over several years (between 1880–1901) as the Pensacola & Selma Railroad and quickly became a part of the Louisville & Nashville Railroad network. The original line proceeded north from Corduroy, Alabama to Selma, Alabama. That portion of the line was abandoned by the Seaboard System prior to the merger with CSX in 1986. There was also a L&N branch that went to Camden from a junction just northeast of Corduroy that was abandoned prior to the merger into the Seaboard System in 1986. The remainder of the line north of Peterman, Alabama was abandoned approximately 1994 to include an 800+ foot tunnel built in 1899 located at Tunnel Springs, Alabama.

This should not be confused with the similarly-named and situated Alabama and Gulf Coast Railway, the former Frisco line only a few miles to the west.

As I’m always looking for things to do on that long stretch of Nowhere, Al, between Mobile and Montgomery, I decided to go find it. After looking at some topo maps, I got a pretty good idea of where it was.

This link in Google Maps gets you to a location where a trail that used to be the tracks crosses the road:


From there, I walked south along the railroad. There were no ties or rails left on this part of the railroad, making a smooth walk.


Obviously by the ruts in the ground, people drive off-road here a lot, so if you have a 4×4 you could just drive right to the tunnel.

Getting close to the tunnel:


Nearing the tunnel entrance, the trail gets pretty muddy. You have been warned.


This picture, you can kind of see how much water is right in front of the tunnel.


It’s actually drier inside the tunnel itself.



I walked far enough to see daylight from the other end, and then turned around.

The ceiling is home to a large number of bats. The sound of them chirping is quite loud, and the whole place smells like guano.


Sargent, Georgia

“Never go in there again!” – a longtime Newnan resident after being shown these pictures and recognizing the location.

 This old place looks to be some kind of workshop. I did not mess around it other than peek in the window.  

I’m guessing this was a pump house.  Looks about the size of the pump house at my Nana’s old place anyway.  

All this stuff is right by the NS railroad but I didn’t see any trains.


This structure whatever it was, has no roof is just stone walls now.


And then there’s this place. An old guard house I guess.

And this is what it was “guarding”. A partially collapsed warehouse full of random shit. 


I shined the light from my phone into this door but it still was too dark to see anything beyond it.

GIMPsplorations, part 3

Continued from yesterday.

Let’s take another look at what we’ve been doing here. Because the “value” of a layer is a single number, you don’t actually have to make the layer gray-scale in order to use it like we have been doing.

As before, I duplicate the layer, and this time I  set the top layer’s mode to “value” without using any channel mixer first.


Now, initially it is not having any effect on the layer below it, since it is an identical copy it has the same value for all pixels.

Now we are going to use Levels to get us back to where we were with the channel mixer, only because Levels previews the changes in real time, we will be able to see what the overall effect will be while we are monkeying with the sliders.

Choose the Blue channel and drag the output slider halfway down. Notice the sky gets darker. This is because blue is not contributing less to the channel’s overall value.


Go on and drag it all the way down to zero, completely suppressing any contribution that blue might have been making to the value.

By the way, at this point if we view our top later as “normal” it looks like this:


The actual layer has red and green but no blue, giving it a yellow hue. But the fact that only its value is affecting the layer below it means we never see this yellow. But I digress.

Notice anything odd about what happened to the blended layers when we went from halfway to no blue at all?


What didn’t happen? The sky didn’t get any darker. It was already as dark with the slider halfway, as it was ever going to get.

Now think about how “value” is calculated. Value is the maximum of R, G, and B. So it a pixel has R=255, G=128, and B=80, it’s Value is 255. The smaller numbers play no role.

So what happened to the sky is, as soon as we had turned down the blue enough that it was no longer the largest of the three numbers, it no longer made any contribution to the value, it became irrelevant. The value of those pixels that used to be mostly blue is now determined solely by their red and green channel, even if there is still almost as much blue left.

If we then go mess with the green, we see the same thing, we only have to turn it down about 1/4 of the way before it stops contributing to the value.


This is just inherently how the HSV color space works. HSV was invented in the 1970s and intended to be used on the primitive computer hardware of the era, so the calculations to convert between it and RGB had to be as simple as possible.

It is, as noted last time, precisely this property that allows those pink faces in the picture to remain more or less as-is. The brightest channel for all of those pixels is already red in the original image, so their green and blue make no contribution to the value, and therefore those pixels do not change value when the overall amount of green and blue is reduced. That effect actually seems kind of beneficial when deal with people.

But what if we don’t like the limited amount of effect that our adjustments have? There are other ways of measuring the brightness of a pixel which take more than one RGB channel into account. Examples would be Lightness and Luminosity.

But GIMP does not give us layer blend modes for Lightness or Luminosity, only Value, so that trick isn’t going to cut it.

There are other modes that can allow a layer to affect the brightness of the layer below it, but we won’t be able to play our little slider games. If we try it with a color layer on top, the hue will be affected.. in the particular extreme case of turning down everything but the red channel, we’ll end up making our final blend be all red. We’ll have to convert to gray to start with, like in the original installment.

(If only GIMP supported non-destructive effects, this would all be moot)

So first start over with an exact duplicate of the base layer, and use the channel mixer to get a monochrome image of 100% red, 0% green, 0% blue.


The first one I want to point out is Darken Only. The way this works is, it compares the all three channels of both layers, and chooses the darker of the two values every time. What this means is, areas that are dark in the monochrome layer, like the sky, and up monochrome in the final blend while areas that were bright like the faces in the monochrome end up using the color of the orignial.

That is, the sky is completely desaturated as well as darkened, the trees partially so, and subjects mostly untouched! That’s kinda neat, I guess.


Now lets look at Multiply. As the name implies, this multplies the values of the two layers, scaled down so that brightness can not blow out the highlights. This darkens everything, but especially the blue and green areas, and also mutes the colors but not as drastically as Darken Only.


You can mess with levels and curves to try to re-brighten it, but the more you do so you will be undoing the darkening of the sky as well.

Overlay is normally supposed to darken an image, but in this case it actually makes it a lot brighter in the areas that have a lot of red. I don’t really feel like trying to understand why.


There are a lot of other modes but they are all really ugly and are left as an exercise for the reader.

Now, we still have at least one more trick up our sleeve. We can use the decompose/recompose workflow to substitute this red channel in for one of the various types of “brightness” channels that exist several of the color models other than RGB.

So, turn off the visibility of the monochrome layer and select the base, original colored layer, and go Colors->Components->Decompose. Look at all those color models to choose from.


Obviously skip RGB and RGBA, we already used channel mixer to accomplish anything we could use that for. Also skip HSV since it is equivalent to what we were doing in the first place.

Let’s try HSL (Hue, Saturation, Lightness), another 1970s era color model for crappy hardware with simple math.

This creates a new image with layers for each of Hue, Saturation, and Lightness. Hide the first two and look at the Lightness channel. It is a greyscale representation of the original image.


Now, what I’m going to do is copy the layer that we originally made using channel mixer, and paste it onto the Lightness layer of the decomposition, completely replacing the contents. I’m going to assume you know how to copy and paste layers in GIMP.

The difference is subtle in the monochrome, but the pasted contents are slightly more “contrasty” than what was there before.


Now, go to Colors->Components->Recompose, to reassemble these layers back into a color layer. GIMP remembers which layer they were extracted from and puts the new image back on the same layer in the original image.

The result, the contrast has been boosted without affecting the saturation like some of the other approaches (that is, the sky is a deeper blue not a dull blue-gray). It is certainly a less dramatic effect that some of the other stuff we’ve been doing though.


Other color models choices should have varying degrees of difference. I don’t feel like looking at them all.

LAB ends up darkening things quite a bit, almost but not quite as much as the Multiply mode did:


CMYK with our monochrome image pasted over the blacK channel and inverted ends up being exactly the same as the Value mode we started with.  I guess that means that the K channel is really just the inverse of the V channel from HSV. Huh.

That’s probably about as much as I feel like messing with this for right now.



GIMPsplorations, part 2

Remember last time, I said that I wasn’t sure what would happen if I tried that particular layering process on a portrait. Well, I tried it, and I was pretty surprised by the result at first, and then realized it wasn’t so surprising after all.

Since the actual technique – create a black and white image of one channel, and then apply it as the value for all channels – was covered last time, I’ll skip the GIMP screenshots and jump straight to results. These examples also use the red channel, as before.
Mind you, I’m not claiming this is a great photo, but it has the advantage of being (a) my own work and (b) has a blue sky in the background.

Now see the before and after:


Notice anything about the subjects? They hardly changed at all, compared to the background. It looks almost as if you separated the humans onto an isolated layer before you messed with the colors of the background layer.
If you are wondering what the blue and green channels do, they notably do not share the red channel’s property of preserving the faces unchanged. Here’s the green version:


This preserves the brightness of the foliage, and probably you could brighten it overall and get the faces back close to the original but the trees extra bright.

The blue, I don’t see much use for but here it is anyway:


Now, why is none of this surprising in hindsight? Because these subjects have more or less pink skin, and the tones of their mostly yellow hair is also captured by the red channel. Their clothing is of course monochrome, so its going to be the same on every channel.This can be seen using the Colors->Decompose tool. This is all three channels of a RGB decomposition and also the V channel of an HSV.


Notice the red channel looks most like the V in the faces, the green looks more like it in the trees, and the blue has a similar (nearly white) sky. This is because the V(alue) channel in HSV is defined as the maximum of the R, G, and B values. No shit, Sherlock!

By the way, if the intention was to make a black and white version that looked good, I would probably not use any of the above as-is. The Desaturate tools’s Luminosity looks better than any of these, and I think 50/50 mix of the red and green channels (which is presumably close to panchromatic B&W film with a yellow filter) looks even better.

Now, the really interesting thing is, I’ve tried this on pictures of people with varying skin tones, and it does pretty much the same thing to everybody.
