Wanting to explore the headwaters of Thomas Creek in Rabun County, I drove FR 150 to where Thomas Creek splits into two branches; "LogRd2" on the above jpeg topo. FR 150 makes a switchback and continues. Just before the culvert, both sides of the road have places wide enough to pull off the road. I parked here. The topo shows an old logging road going up the right side of the creek but I noticed a good path heading up the left side. So, that's the way I went.
