The last photo was taken of Helton Falls in Union County. Take 129 South to Hwy 180. Turn left. Turn right on Richard Russell Scenic Hwy. Go about 3 miles and turn right on Hatchett Creek. Stay on that road until you come to the falls on your left. There is one point where you need to bear to the right. Nice path to the falls or just view from the parking area.
This is 1/8 mile off of a major Highway. I think there must be a story to this one. I will find out and let you know.
