The Mighty Chattahoochee

Two mapping days in a row. 85 degrees today. I start at a litle after seven and quit when it gets too hot.

Printed out more basemap, and started out on the area west of the small powerline. This is a big area, with no obvious handrails to use. My usual tactic is to make a handrail out of something so that I can enclose an area, then radually work away on the interior. I used the northern boundary of the inholding, which has a nice forest road along it. I mapped that out about 700 meters, then mapped a stream north west all the way to the river. The terrain is very pretty here. The stream is in a wide reentrant until the last 100 meters when the hills close in on it and it passes through a two contour deep channel down to the river.

Then I worked my way back up one of the hills and discovered an area that had been logged 20 or 30 years ago. It was only logged along the very top of the hills and spurs. Very odd. This is all hardwood forest, and the loggers did not replant, but let the volunteer trees come back. As a result, there is everything from bare clay to grass, blackberyy canes to muscadines, and trees of every height. Mapping the vegetation changes will be a chore. I predict I will spend a lot of time trying to get this right. My usual tactic is to map the edge as a linear feature first. I tried that and managed to get confused, but by that time the heat was getting to me.

I uploaded plenty more pictures, including a couple of the river. Check them out.
