One Year Before the Big Event

From Chattahoochee Bend


Took three days and went back to finish the construction details on the map. They are on track to open the park in June, which was the original opening time frame. They were paving the RV campground while I was mapping it (the asphalt was still hot!). Also added the hiking trails that the Friends of the Park group have been working so hard on. They have constructed a river trail that goes from the day-use area all the way to the bend. Also a small trail between the visitor center and a small trailhead parking lot.

The photo above is the observation platform down on the river bank. Massive! I doubt a 500 year flood would have much impact.

I added some more pictures of the park in April - one year away from the big event!

The Southwest Corner

From Chattahoochee Bend


There it is - the far southwest corner. I will probably be the only orienteer ever to visit this spot - and I'll probably never go back.

Error of Closure

The Heard County 100 acres, for which I have no basemap, was an interesting challenge. A few genreations ago, surveyors would have used a plane table to map this area. Basically a flat board and a heavy wooden tripod, it also had a large compass rose and rotating arm used to take bearings. The whole contraption would be carried out into the field and set up at a point of interest, with the plane table leveled and oriented to north. Then bearings would be taken to other points and the distance measured with chains. What a lot of work!

Essentially I am using a simplified plane table. My map board is the table, with the basemap sandwich of materials taped to it, along with a baseplate compass. When I want to add something, I level the board, orient it to north, use my ruler to sight to the next point, and either pace the distance or use my laser rangefinder. So it's the same technique, just simplified, lighter, and considerably more mobile.

In the Heard County 100 I first mapped the linear features, then filled in the point features, building everything gradually using what I had already done. The southernmost stream ran across the map for about 600 meters before emptying into the river. No hint of it on my blank basemap, of course, so I used my simple plane table to take bearings along the stream and pace it off. By the time I got to the river I was 10 meters too far. That's what they call the "error of closure". Imagine mapping a fence that encircles a field. How far off are you when you get back to where you started? That's the error of closure. 10 meters over 600 meters is pretty good.

I didn't do nearly as well with the contours. One part of the Heard 100 is a gently sloping hill. The contours are 100 meters apart! I could draw them in any direction and it would look correct. The easiest way is to draw an imaginary line down the spurs and the bottom of the reentrants to get a direction, then imagine a level line where the contour goes. But if there are no spurs or reentrants I have a problem.

Well, the orienteers will be more than willing to tell me how well I did, usually as soon as they finish their course while they are still hot and bothered. Probably only the upper-level runners will every see the Heard 100, which is probably a good thing.

Christmas 2010 update

From Chattahoochee Bend


I've been hard at work, closing in on the final bits. My main problem is the very long walk to get to the final SW corner of the map. I have succeeded once in getting entry to drive around from the construction company. It's very hit and miss in late December. The walk in is about 3 miles. The walk out is 3 miles. Plus the one-mile-an-hour mapping amble that I do. That makes for a very long day.

Here's the progress map. As you can see, only the 100 acres in Heard County in the far SW corner are left:

From Chattahoochee Bend


I have no base map for those 100 acres, so I will have to resort to the old fashioned methods. It will take a couple of days at least, maybe more. Map the linear features first using compass and pacing, then fill in the details. It's not fast, and I wouldn't want to do a large area this way, but it does work.

Estimated time of finish? New Year's day 2011.

Armadillos

From Chattahoochee Bend


I surprised him (her? how do you tell?) rooting around in the leaves. He scurried into his hole. I waited, getting my camera ready. They have very poor eyesight - I probably looked like a tree standing there. He poked his head back out and I took his picture.

I've been seeing a lot of them lately. My theory, which may be totally bogus, is that it's too cold at night for them to forage, so they have been coming out when the temperature warms up in the afternoon. It was probably 50 degrees when I took that picture.

How Much Longer?

From Chattahoochee Bend


The Visitor Center is finished!

If nothing interferes, I hope to "finish" the map before the New Year. I put "finish" in quotes because I am going to finish before the construction is finished. I will have to update the campground and the rest of the park road when they are done. Also the hiking trail currently under construction by the Friends of the Park. The park is supposed to open in the summer of 2011.

Another Week of Field Checking

Took advantage of a vacation week to get in 5 straight days of field checking and one day of drafting. What a week! I'm exhausted. Let's see if I can remember what happened.

Day 1: Finished the marshes on the west map, see previous blog post.
Day 2: Mapped all the low hills between the new road and the marshes, out as far as the campground.
Day 3: Mapped the strip of land between the new road and the big power line, finishing this base map page. This narrow area had to be mapped, of course. Who knows if it will ever be used for any real orienteering.
Day 4: Started the final base map page. This is the area that extends south past the campground along the river. I walked all the way out there, then followed the boundary around, then walked all the way back. By my calculation, a distance of 14 km. I vowed never to do that again, and when I got home I phoned a contact I had with the construction company and got permission to drive out there.
Day 5: Drove out just short of the campground and parked, then mapped in the new area. For the first time I got behind the gate and drove on the new park road. What fun!. But the logging roads are terrible, even for my pickup truck. Very afraid of getting stuck, but managed to get out there and back OK.
Day 6: Collapsed in front of the computer and caught up on the drafting.

Have rubber boots, will wade

From Chattahoochee Bend


I should be done with the marshes now, at least until I get out past the campground. I spent the day wading with my rubber boots on. I had left blank spots on the map where every marsh was in this area, saving them all up so I could wade through them all at once, discovering all their secrets. What did I find? More of the straight ditches. Someone, long ago, tried to drain these marshes. I hate to mention it, but it could have been slaves - you always have to bear that in mind in this area. I don't know for sure.

The attempts to drain it didn't work well, and when everything was abandoned the beaver took everything back. They are farming it now, and doing an excellent job at keeping it wet.

The hills crowd back in on the river now, so I will be back in the low hills at least until I get past the campground and picnic area. Saw some evidence yesterday that heavy equipment is moving in that direction, using the old logging roads to get around the bridge construction. Probably pouring concrete culvert footings. I will work around the last of the construction and finish this area up soon.

Mired in the Marsh










From Chattahoochee Bend

I have spent the last few trips down in the floodplain picking away at the marshes and flat areas. One more trip down there and the biggest wet areas should be done - I need to take my rubber boots and capture all the details of the marshes.

They are very beautiful, in a cold, wet, muddy sort of beauty. I imagine the snapping turtles and beavers are very happy with them. Orienteers, not so much. The difficulty will be in getting around them. They flow west or northwest, at an angle to the river, and block access to the sand hills on the river edge, so good course planning will place them in the way of the legs so that they have to be navigated around somehow - or crossed for the adventurous.

I've posted a bunch more pictures also. Found an impressive Osage Orange tree (or Bodark) down on the banks of the river. Unrecognizable usually, but this time of year the "oranges" are very visible, looking like someone scattered a bucket of green tennis balls on the ground. Don't eat them!

The big question is - when will I finish the map? Once these marshes are done I will climb back into the hills and work my way out past the picnic area. Then the map turns south along the bank of the river. I have never even been down there, so I can only guess that it is more of the same. It's a small area compared to what I have already done. Adding to the difficulty is the fact that, at the very southern tip, it crosses into Heard County. I have no basemap for that area.  Uh oh.

I plan to take a week's vacation before Christmas and should get in a few more days then. And I will probably spend most of the time between Christmas and New Year's mapping, hoping to finish the whole thing before 2011. Of course, it won;t be "finished". The construction is still ongoing, and I will finish the map before the construction is finished. I'll have to make "updates" as they finish up the campground and picnic areas, as well as the trail construction.

Heading for a picnic

I started a new page of the basemap, a very large page, about twice as large as normal. It extends all the way out to the day-use area, also known as the picnic area. The first task, as usual, is to fix down the new road, so I followed it all the way out, penciling it in as I went. Here's what the picnic shelters look like:

From Chattahoochee Bend


This area of the map will finish all man made objects. It extends from the maintenance building, past the campground and the second residence to the picnic area, boat ramp, and primitive camping. This is going to take a while to finish, but once that is done, I will turn south along the river for the final part of the map.

Another milestone reached

From Chattahoochee Bend


A totally arbitrary one, but significant anyway. I finished everything from Flat Rock road west to the northward jog in the boundary line, south of the big power line. That is a 2 sq km chunk of the West map, which means I am about half done with the West map.

This is the heart of the developed area of the park, and is the area that people drive through when they arrive. It includes the Visitor Center, Adirondack Camp, one of the ranger residences, and the maintenance building. Also 2 small trailhead parking areas.
It also has about a third of the rock in the park. The rest of the rock was in the east map, already finished. Which means I am done with rock now, except for the occasional spot here and there.

The rest of the West map includes the campground and picnic area - that will be next.

I can also report an unsubstantiated rumor that the observation platform up in the bend of the river will be built in phase one construction, and the road will be improved so that people can get to it. This is good, since we hope to use that area for parking for our orienteering meets up in the bend. Much more on that later...

I've been keeping up with the road construction, mapping it about as fast as they construct it. It is paved now as far as the visitor center and the gravel has been laid in preparation for asphalt as far as the Maintenance Building.

The next section of the west map descends to the river, back in the floodplain. At one point the floodplain is 400 meters wide - yikes! Wish me luck down in there...

A break from the heat

Finally, the temperature dropped 20 degrees, which put the high in the low 70s. I put in a long 9 hours, the longest day since last Spring. Managed to finish another page of the base map.

From Chattahoochee Bend


This may be the largest beech tree in the park, roughly 10 feet around, which would make it about 36 inches in diameter. It's down in a beech bottom west of the Adirondack Camp. And no, I did not put it on the map...

The heat continues

From Chattahoochee Bend


A month of 90 degree days. What a difference from last year, when we got 10 inches of rain and the river flooded. Worked in the area north of the visitor center. There is a long swamp in the bottom of a forked reentrant that has to done - it leads all the way to the big power line and eventually out to the river, but that part is already mapped.

Actually found two bare rock areas today. They were covered with grass for the most part. What are they doing this far west? But it's nice to have them on the map for some variety.

Park road gets asphalt

From Chattahoochee Bend


The first layer of asphalt is down on the new park road, at least as far as the visitor center. Looks good. Of course, there is still a lot of road to be constructed before it gets all the way out to the picnic area and the boat ramp.

From Chattahoochee Bend


I worked west of the visitor center today and once again got confused by the old logging roads. If only I had a map! Oh wait, I'm making the map. They never go where I think they are going to go, and new ones keep appearing out of nowhere. All secrets will be revealed soon. Hopefully it will be a challenging area for some orienteers even with the map.

Beautyberry

Fall means the weeds are blooming. Spent the morning in the thinned pine forest northeast of the visitor center. There were workers out on the new park road putting out landscape netting and grass seed on the banks. They had salsa music blaring from their truck radio - the sound really carries!

Here's the weed of the day - beautyberry:

Starting a new page

It's mildly exciting to start a new page of the basemap - in a long project like this any sign of progress is encouraging. I did as much as I could above the big powerline north o the maintenance building, so this new page is west of the visitor center out to the maintenance building. The first step is to map out the new road. At this point I just map the edge of the clear cut. I also found the new powerline. It cuts south from the big powerline and swings around south of the Adirondack camp on it's way to the visitor center.

Compare these two photos of the visitor center:

Looks like they are making some progress!

Meeting with DNR

A small portion of the brain trust of GAOC gathered together at the under-construction park for a meeting with our contacts from the Department of Natural Resources. We got an update on the construction and a tentative OK to begin planning an A meet at the park sometime in 2012 (hopefully the map will be done by then...). The meeting was great and we learned a lot. Bottom line - it looks like we will have an A meet at Chat Bend in 2012. I know that's a long way off but we have to plan way in advance.

After the meeting we had a walkabout and I showed Steve, Charlie, and Laurie some of the highlights of the park.

A Week of Mapping

I took another of those working vacations last week and managed to map 7 days out of 10 before the 4th of July holiday. Lots more pictures on the photo page. I worked the area west of Flat Rock Road out to the under-construction visitor center, which is about a kilometer away. I worked north to the powerline and the logging road that is being used for access by the construction crews. The new park road bisects this area.

Lots of boulders and bare rock in a continuation of the band from east of Flat Rock Road. It runs out to the southwest, of course, just like before.

From Chattahoochee Bend


An advantage of being out there during the week, instead of on the weekends like usual, was that I was able to see some of the construction on the new park road. I peeked out from the trees, of course - I don't think anyone ever saw me. I have permission to be there, but I did not want to disturb anyone or get in the way. Here's a concrete pumper getting ready to pour a footing for a culvert:

From Chattahoochee Bend


Very interesting to see. One day that swath of destruction will be a beautiful park entrance road.

The next area I will work will be north of the park construction, down in the floodplain. Maybe things will go a little faster without the ever-present rock to contend with.

Yellowjackets: 5 - Mapper: 0

That's one of the hazards of mapping in the summer, the yellowjackets. They build their hive in stump hollows in the ground. The slightest disturbance and they aggressively defend their home. Grab a sapling for balance, trip on a root, or step on a wobbly rock that is near the entrance to their burrow and they come boiling out. I've heard that they give a warning butt to the intruder, but there are so many deerflies and horseflies and who knows what else buzzing around that i would never notice it. Then the stinging starts. My reaction is to run, heart pounding and adrenalin pumping. I'd like to shake the hand of the man that could stand still or play dead in the face of yellowjackets.

I got stung five times, on each leg, each arm, and the side of my head. Nothing to do but accept that is going to hurt and suck it up. I think it's better to keep moving than to sit down and cry about it. But I am not allergic to bee stings.

I finally mapped the boulders that are the banner image for the web site. I first photographed them over a year ago, on my very first recon trip to the park. Have they changed any?

Cicadas Sing at 9:45

All is quiet, at least from the cicadas, at seven, and eight, and even nine. But at 9:45 they burst out with their incessant singing. I'm no expert, but it must be the temperature. They sing in the day, they sing in the night, so it can't be the light. Once the temperature gets up to about 80, they sing out, and don't stop until it cools off late at night. That's my theory and I'm sticking to it.

Mapped more of the area around the high point today. Lots of little bare rock areas and boulders. It should be interesting terrain for orienteering. I also found a hollowed out spot on the top of a rock that looks suspiciously human made. A grinding stone?

From Chattahoochee Bend


Lots of dead tress in this area, still standing. Why? I have no idea, unless it's the shallow soil above the granite outcropping.

From Chattahoochee Bend


I only do half days in this heat - more tomorrow.
