I didn't find as many falls as I'd hoped, but I did get distant views of a couple, and a good view of a small one. The small one is at the end of a very short driveway/old road (not sure which) that ends abrutly at a drop-off into the creek, but it looks like it's possible to get down and cross the creek to what looks like a trail that goes back upstream. One day I'll go back and try that, because it's the same creek as the one with the falls I've called #2 and I might be able to get better pictures.
Since the roads actually ARE labeled private, I won't give exact directions but the three falls I got were all on roads that are to your left, and before the pavement ends, as you drive down Monument Rd, which turns off of Hwy 136. I found them by driving with my windows open and listening for falls.
